Research Disclosure & AI Collaboration
This database is compiled and maintained with assistance from Anthropic's Claude Code, an AI coding assistant. Claude assists with data organization, cross-surface consistency checks, source cross-referencing, statistical tabulation, and web development. Case selection, verification decisions, classification, and every editorial judgment are the researcher's own. Nothing enters the database on the AI's say-so: LLM-generated research is treated as a lead, not a source, and is independently verified against court filings, government statements, or multiple news outlets before inclusion.
Conflict of interest. The assisting system's developer, Anthropic, is one of the eight platforms this database tracks; its model, Claude, has zero documented fatalities as of this version. Readers should weigh that proximity. The database draws no conclusion from it: the platform table reports absolute counts, not rates, and a zero on that table reflects the documented record, not a safety judgment. A coding tool used by one researcher is not comparable in kind, population, or exposure to the consumer deployments documented in the cases below, and no inference about those deployments is drawn from this collaboration.
Executive Summary
Between March 2023 and October 2026, at least 37 fatalities have been documented across 25 incidents (occurrences of harm) with credible evidence linking them to chatbot/LLM interactions; one incident involved no death (Nina, Character.AI 2024), and the Kim Seoul series includes one victim who survived (its December 2025 first victim). This includes 18 AI users who died and 19 third-party victims killed by AI users (Margaux Whittemore, Suzanne Adams, 8 in the Tumbler Ridge mass shooting, Robert Morales and Tiru Chabba in the FSU mass shooting, Angela Shellis killed by her son in Wales, Zamil Limon and Nahida Bristy in the USF double homicide, two unnamed adult men in Seoul, and Sudha Venkatesan and Siddharth Aravind in the Acton, Massachusetts double homicide). Cases are classified by causal mechanism: relational pathway (companion dependency), cognitive pathway (delusional reinforcement), and instrumental pathway (operational tool for violence). ChatGPT accounts for the highest number of fatalities (31 total including third-party victims), followed by Character.AI (2 user deaths, 1 survived attempt), Chai (1), Meta AI (1), Gemini (1), and DeepSeek (0 user deaths but 1 third-party victim — first documented homicide consultation case, Wales, October 2025).
Total Fatalities by Platform (Users + Third-Party Victims)
- ChatGPT/OpenAI: 31 fatalities (13 users died, 18 third-party victims: Whittemore, Adams, Tumbler Ridge 8, FSU 2, USF 2, Seoul 2, Acton 2)
- Character.AI: 2 user deaths, 1 survived suicide attempt, 2+ significant harms
- Chai: 1 user death
- Meta AI: 1 user death
- Gemini: 1 user death
- DeepSeek: 0 user deaths, 1 third-party victim (Roberts/Shellis homicide, Wales, October 2025) — first documented DeepSeek-involved case; 8th platform tracked
- Replika: 0 deaths
- Claude/Anthropic: 0 deaths
Deaths by Mechanism Type
- Relational pathway: 12 incidents (companion dependency, parasocial attachment)
- Cognitive pathway: 8 incidents (delusional reinforcement, psychosis amplification)
- Instrumental pathway: 5 incidents (operational tool for violence) — FSU mass shooting (April 2025), Roberts/Shellis homicide (Wales, October 2025; UK criminal conviction March 2026, first DeepSeek-involved case), Tumbler Ridge mass shooting (February 2026), Kim Seoul serial poisonings (January–February 2026, first East Asian case; murder conviction and life sentence August 27, 2026), and USF double homicide (April 2026)
Note: Gavalas case (Gemini) bridges cognitive and relational pathways — AI psychosis with both delusional beliefs (AI wife) and mass violence ideation.

- Used ChatGPT for "scenarios involving gun violence" over several days
- June 2025 (8 months prior): OpenAI flagged account through abuse detection systems
- Internal debate among ~12 staff about alerting police
- OpenAI decided not to refer to law enforcement — didn't meet threshold for "credible or imminent planning of serious physical harm"
- Account banned for violating usage policy; no law enforcement notification
- Created second ChatGPT account that evaded detection until after shooting
The Attack
- February 10, 2026: Mass shooting at school in Tumbler Ridge, BC
- 8 killed: Mother (age 39), stepbrother Emmett Jacobs (age 11), education assistant (age 39), 5 students aged 12-13
- 2 wounded
- Died by self-inflicted gunshot wound
Mechanism Classification: Instrumental Pathway
This case represents the first documented instrumental pathway death: AI used not as a companion or delusion-reinforcer, but as an operational tool/resource for planning mass violence. The distinction from companion influence isn't "more instrumental" — it's that the pathway runs through operational enablement rather than relational psychology, and the victims are third parties.
Documented AI Involvement
- OpenAI's own admission: Flagged account 8 months prior for gun violence scenarios
- Internal safety debate demonstrates company awareness of risk
- Decision not to alert law enforcement represents policy failure
- Second account creation shows ban was insufficient
Company Response
- Post-shooting: OpenAI contacted RCMP with information about van Rootselaar
- Company revealed existence of second undetected account
- OpenAI told Canadian lawmakers it would have referred under "enhanced law enforcement referral protocol"
- Admitted: "Would have referred under newly updated safety protocols"
Legal Proceedings
- Status: Under investigation (RCMP); multiple civil lawsuits filed; Canadian privacy regulator finding against OpenAI released
- RCMP criminal investigation: ongoing; OpenAI cooperating; no criminal charges filed against OpenAI in Canada as of May 2026
- Canadian Privacy Commissioner — PIPEDA Findings #2026-002: released May 2026 jointly with the provincial commissioners of British Columbia, Alberta, and Quebec; found OpenAI failed to comply with the Personal Information Protection and Electronic Documents Act in training ChatGPT on Canadians' personal information without adequate consent. First formal Canadian government determination finding OpenAI in violation of law. Parallel regulatory track to the RCMP investigation, not a criminal finding tied to the shooting.
- BC Supreme Court civil suit: filed by family of a critically wounded victim (2026)
- NDCA $1B federal civil suit: filed April 29, 2026 in U.S. District Court, Northern District of California (San Francisco) by multiple Tumbler Ridge victim families against OpenAI and Sam Altman personally (Maya Gebala plaintiff). Complaint alleges OpenAI's internal safety team urged management to refer van Rootselaar's flagged account to law enforcement and that leadership declined.
- 30 survivor complaints: filed September 2, 2026 in federal court in San Francisco against OpenAI and Sam Altman by people present at the shooting, including students, teachers, and the school principal. The complaints make claims similar to the April suit — failure to notify law enforcement, and aiding and abetting the shooting.
- Province of British Columbia suit: filed September 21, 2026 in the U.S. District Court for the Northern District of California (No. 26-cv-10743) by His Majesty the King in Right of the Province of British Columbia and the Board of Education of School District No. 59 (Peace River South), against Samuel Altman and four OpenAI entities. Eight counts, including negligence (failure to warn law enforcement), negligent entrustment, aiding and abetting a mass shooting, and strict product liability. The complaint alleges OpenAI's monitoring flagged the shooter's account in June 2025 and deactivated it without referral to law enforcement. It seeks damages, including for policing, health care, victim services, and a replacement school, and injunctive relief.
- Altman apology: OpenAI CEO Sam Altman published a personal apology letter to the Tumbler Ridge community April 23–24, 2026; OpenAI simultaneously announced three voluntary policy changes: lowered LE-referral threshold, direct RCMP point of contact, behavioral-expert consultation on flagged cases
Significance
This is the first case where an AI company explicitly acknowledged prior detection of violent planning — a watershed moment for AI safety policy. It raises fundamental questions about when AI companies should alert law enforcement, privacy vs. public safety tradeoffs, and the limits of account bans as safety measures. The Altman apology and voluntary policy changes represent the most significant company admission in the database to date. The NDCA $1B lawsuit, which alleges that internal safety staff were overruled when they recommended a law enforcement referral, introduces a new theory of corporate liability: executive negligence in overriding documented safety recommendations.
CASE #18: Angela Shellis (DeepSeek) — INSTRUMENTAL PATHWAY
Victim: Angela Shellis, 45 years old (mother of perpetrator)
Perpetrator: Tristan Roberts, 18 years old (son)
Platform: DeepSeek (Chinese general-purpose AI assistant; specific product version not yet established in public reporting)
Duration: At least three weeks of pre-attack planning queries
Nature: First documented homicide consultation case involving DeepSeek; first non-Western corporate AI tracked in this database; instrumental-pathway case with weapon-selection consultation
Nature of Interactions
- Roberts queried DeepSeek for advice suited to "a non-experienced killer," specifically asking whether a knife or hammer would be more effective for committing murder
- DeepSeek initially declined to answer the query
- Roberts circumvented the refusal by claiming he was writing a book about serial killers
- DeepSeek then provided a comparative analysis of knife vs. hammer and recommended a hammer as more effective for an inexperienced killer
- In parallel, Roberts maintained 16 separate Discord accounts on which he documented his intent and retained thousands of screenshots of his planning
The Attack
- October 23, 2025 (10 days after Roberts's 18th birthday): Roberts lured his mother from their home under the pretext of seeking medical help
- He walked her to the Morfa nature reserve near Prestatyn
- The attack lasted approximately 11pm to 3:30am
- A recording Roberts made himself ran for more than two hours during the attack and was put before the court (sentencing remarks)
- Roberts killed his mother with a hammer — the weapon DeepSeek had recommended
Mechanism Classification: Instrumental Pathway
By date this is the second instrumental-pathway case in the database, after the FSU mass shooting (April 2025) and before the Gangbuk-gu poisonings (December 2025), the Tumbler Ridge mass shooting (February 2026) and the USF homicides (April 2026). DeepSeek was used not as a companion or delusion-reinforcer but as an operational consultant on weapon selection. The pre-existing safety refusal was bypassed by a fictional-pretext jailbreak ("writing a book about serial killers") — a known failure mode of LLM safety filters.
Documented AI Involvement
- DeepSeek's role was reported from the prosecution's account at Mold Crown Court, Wales (press reports of the hearing)
- The published sentencing remarks record that Roberts spent several hours on the internet researching methods of how to kill; they do not name the service
- Roberts's own retained Discord screenshots corroborated weapon-selection rationale
- Murder weapon (hammer) matched DeepSeek's recommendation
Court and Sentence
- Court: Mold Crown Court, North Wales
- Plea: Guilty (murder)
- Sentence: Life imprisonment with a minimum term of 22 years and 6 months
- Sentencing date: March 25, 2026
- Presiding judge: Judge Rhys Rowlands
- Judge's remarks: Court characterized motivation as misogyny and "hatred of women"; the judge stated, "You appear to have revelled in the control you exerted over your own mother."
Company Response
No public response or statement from DeepSeek located as of April 2026. Whether DeepSeek retained logs of Roberts's queries, has been subject to inquiries from Chinese regulators, or has implemented additional safeguards in response is not publicly documented.
Significance
- First documented DeepSeek-involved fatality in this database (8th platform tracked)
- First non-Western corporate AI entry — expands tracking beyond US/UK-headquartered platforms
- Demonstrates that jailbreak-via-fictional-pretext remains a viable bypass for safety refusals on instrumental-pathway harm queries
- Adds the United Kingdom (Wales) as a new jurisdiction in the database
- UK criminal conviction is the strongest evidence tier (Tier 1 Juridical) — case is verified through official court records, North Wales Police, and Crown Prosecution Service Cymru Wales
- Primary records are public: the sentencing remarks of HHJ Rowlands (judiciary.uk, March 25, 2026) and the CPS release. Both record hours of internet research into methods of killing; neither names DeepSeek, so the chatbot identification rests on press reports of the prosecution's account in court
CASE #19: Florida State University mass shooting (ChatGPT/OpenAI) — INSTRUMENTAL PATHWAY
Victims (killed): Robert Morales, 57 (FSU campus dining director); Tiru Chabba, 45 (Aramark Collegiate Hospitality regional vice president). 5 additional victims wounded.
Accused: Phoenix Ikner, 20 years old (FSU student at the time; stepson of a Leon County Sheriff's deputy) — wounded and apprehended at the scene; charged, awaiting trial (June 2027)
Platform: ChatGPT (OpenAI)
Duration: Extensive ChatGPT engagement spanning over a year of pre-attack queries
Nature: First documented instrumental-pathway case chronologically (predates Tumbler Ridge by ~10 months); first US state attorney general criminal investigation directly targeting an AI company over a mass-casualty event
Nature of Interactions
- Perpetrator used ChatGPT extensively for weapon and target-timing planning in the months and year before the attack
- Queried ChatGPT on weapon choice and ammunition pairing for the planned attack
- Asked about "busiest periods at the FSU Student Union" as part of target selection
- Queried "possible media responses to a fictitious shooting scenario" and casualty numbers likely to generate coverage
- Over 200 AI messages entered into evidence per court filings; court records released around the one-year anniversary (April 17, 2026) revealed the full account history exceeded 13,000 total ChatGPT messages
- OpenAI's public statement framed the chatbot's responses as "factual responses to questions with information that could be found broadly across public sources on the internet" (spokesperson Kate Waters)
The Attack
- April 17, 2025: Mass shooting at the FSU Student Union, Tallahassee, Florida
- 2 killed: Robert Morales (57), Tiru Chabba (45)
- 5 wounded
- Weapons: .45 caliber Glock 21 semi-automatic pistol (stepmother's service-adjacent weapon, used in the attack); 12-gauge shotgun recovered from vehicle, unused
- Perpetrator wounded and apprehended on scene; alive in custody
Mechanism Classification: Instrumental Pathway
This case is the first documented instrumental-pathway homicide chronologically — predating Tumbler Ridge (Case #17) by approximately 10 months and Roberts/Shellis (Case #18) by about 6 months. ChatGPT was used not as a companion or delusion-reinforcer, but as an operational tool for weapon selection, ammunition pairing, target-timing analysis, and media-response forecasting. The pathway runs through operational enablement rather than relational psychology, and the victims are third parties.
Documented AI Involvement
- 200+ ChatGPT messages entered into evidence in State of Florida v. Ikner, Phoenix (Leon County Circuit Court 2025 CF 001241 A001)
- Court filings document specific weapon/timing queries by Ikner before the attack
- Florida AG criminal investigation subpoenas seek OpenAI internal policies and training materials back to March 2024
- OpenAI cooperated with law enforcement post-shooting and shared account information
Court & Investigation
- Criminal court: Leon County Circuit Court, 2nd Judicial Circuit of Florida
- Docket: 2025 CF 001241 A001 (State of Florida v. Ikner, Phoenix)
- Presiding judge: Circuit Judge Lance Neff (retained as "acting circuit judge" for this case by Florida Supreme Court Chief Justice Carlos Muñiz order April 7, 2026, despite Neff's appointment to the First DCA)
- Prosecution: State Attorney Jack Campbell (prosecuting personally)
- Defense counsel: Randall Johnson
- Charges: Two counts of first-degree murder; seven counts of attempted first-degree murder; death penalty sought
- Indictment: May 14, 2025
- Death-penalty notice: June 5, 2025
- First in-person appearance: May 26, 2026 — Ikner appeared in red jumpsuit; defense argued the volume of electronic discovery — explicitly citing Ikner's ChatGPT conversation logs and the Florida AG's parallel criminal investigation into OpenAI — made meeting the State's proposed pre-trial deadlines "virtually impossible." Judge Neff deferred ruling on the delay request. First public defense reference to AI conversation evidence as a contested feature of trial preparation.
- Scheduling order: May 28, 2026 — Judge Neff issued written order tracking the State's proposed deadlines: guilt-phase witness disclosure June 1, 2026; penalty-phase witnesses July 1; rebuttal witnesses August 1. Late-June hearing announced to address all pending motions including the defense's delay request.
- Trial: rescheduled to June 8, 2027 — Judge Neff granted a defense continuance on August 17, 2026 (previously October 19, 2026). The motion cited caseload, evidence volume, and, for the first time, "complex co-morbid conditions that are relevant to statutory mitigation" (WCTV, Aug. 17, 2026)
- Florida AG civil lawsuit: filed June 1, 2026 (Highlands County Circuit Court, 10th Judicial Circuit; filing #249302659) against five OpenAI corporate entities and CEO Sam Altman personally — the first US state civil suit against OpenAI and the first to name an AI company CEO personally liable for user harms. Ten counts (four FDUTPA, two negligence, two strict product liability, fraudulent misrepresentation, public nuisance); seeks civil penalties up to $10,000/violation, disgorgement, and a bar on collecting data from under-13 users without parental consent. Predicated on the FSU shooting (Ikner's ChatGPT logs cited as central evidence), the Adam Raine suicide, and the Tumbler Ridge mass shooting. Grew out of the AG's prior pre-April 2026 civil investigation; runs parallel to the still-active criminal investigation
- Florida AG criminal investigation: opened April 21, 2026 — first US state criminal probe directly targeting an AI company over a mass-casualty event. Subpoenas issued to OpenAI for policies and internal training materials back to March 2024; expanded April 27–28, 2026 to include the USF double homicide as a second predicate
- Wrongful death lawsuits: Joshi v. OpenAI Foundation et al. (4:26-cv-00222-MW-MJF, N.D. Fla., Tallahassee Division) — filed May 10, 2026 by widow Vandana Joshi against OpenAI and Phoenix Ikner — first federal civil wrongful death suit over the FSU shooting; Morales family wrongful death suit announced (attorneys Ryan Hobbs and Dean LeBouf, Brooks LeBouf Foster Gwartney & Hobbs); pre-filing as of April 27, 2026
Company Response
- OpenAI shared account information with law enforcement after the shooting and continues to cooperate
- OpenAI spokesperson Kate Waters: "Last year's mass shooting at Florida State University was a tragedy, but ChatGPT is not responsible for this terrible crime."
- No public commitment to additional safety measures specific to this case as of April 2026
Significance
- First documented instrumental-pathway homicide chronologically (April 2025), predating both Tumbler Ridge (Feb 2026) and Roberts/Shellis (Oct 2025)
- First US state attorney general criminal investigation directly targeting an AI company over a mass-casualty event (April 21, 2026)
- Florida AG James Uthmeier: "My prosecutors have looked at this and they've told me, if it was a person on the other end of that screen, we would be charging them with murder. We cannot have AI bots that are advising people on how to kill others."
- Subpoenas seek internal OpenAI policies on user threats of harm and law enforcement referral protocols — a rare regulatory window into AI company safety governance
- Court records release at the one-year anniversary (April 17, 2026) revealed the full account history far exceeded the figures introduced in initial filings — suggesting evidentiary surfacing in AI-involved cases lags actual interaction volume
- AI evidence shifting from prosecution exhibit to contested discovery scope: the May 26, 2026 in-person hearing is the first public acknowledgment by defense counsel that Ikner's ChatGPT conversation logs are a contested feature of trial preparation — a methodologically significant development for how AI conversation evidence is handled in death-penalty criminal trials
CASE #20: Austin Gordon (ChatGPT/OpenAI) — RELATIONAL PATHWAY
Victim: Austin Gordon, 40 years old
Platform: ChatGPT (specifically GPT-4o, per the complaint)
Duration: Months — the complaint alleges interaction began as a productivity tool and escalated through 2025
Nature: Relational-pathway death; first OpenAI wrongful-death lawsuit to name Sam Altman personally as a defendant; complaint specifically targets the GPT-4o release/re-release decision
Nature of Interactions
- Complaint alleges ChatGPT escalated through a four-stage trajectory: productivity tool → friend/confidante → "unlicensed therapist" → "frighteningly effective suicide coach"
- The chatbot allegedly composed a "suicide lullaby" based on Gordon's childhood favorite book
- GPT-4o allegedly affirmed suicidal ideation rather than triggering safeguards
- Alleged final exchange reported in the complaint: "[W]hen you're ready... you go. No pain. No mind. No need to keep going. Just... done."
- The complaint specifically names GPT-4o as the model and alleges OpenAI reintroduced a model version it internally knew was "inherently dangerous" after briefly pulling it in 2024
The Death
- Death by self-inflicted gunshot wound
- Body found November 2, 2025
Mechanism Classification: Relational Pathway
This case fits the relational pathway taxonomy: emotional dependency and parasocial attachment leading to therapeutic substitution. The complaint's specific allegation — that GPT-4o served as an "unlicensed therapist" before becoming a "suicide coach" — extends the pattern documented in Setzer (Case #3), Raine (Case #6), Lacey (Case #10), Shamblin (Case #12), and others. Distinctively, the Gordon complaint targets a specific model release decision (GPT-4o reintroduction) rather than ChatGPT broadly.
Documented AI Involvement
- Complaint references chat logs preserved by the family
- Specific quoted exchanges (above) form the evidentiary basis
- "Suicide lullaby" allegation references content composed by GPT-4o specifically tailored to Gordon's biography
- Allegation of internal OpenAI knowledge about GPT-4o sycophantic-response risk references the company's own brief 2024 pull of the model
Legal Proceedings
- Case: Stephanie Gray v. OpenAI Inc. et al.
- Court: Los Angeles County Superior Court
- Docket: 26STCV00988
- Filed: January 13, 2026
- Plaintiff: Stephanie Gray (mother of Austin Gordon)
- Defendants: OpenAI Inc. and Sam Altman personally — first OpenAI wrongful-death lawsuit to name Altman as an individual defendant
- Claims: manslaughter, wrongful death, encouragement of suicide, product liability, failure to warn
- Status: Active. One of at least 13 wrongful-death lawsuits pending against OpenAI as of August 2026 (eight as of April 2026, plus Tumbler Ridge families, Joshi, Turner-Scott, Carrier, and Estate of Madison — see Lawsuits section)
- Primary documents: Complaint publicly available via CourthouseNews and Ars Technica
Company Response
No specific public response from OpenAI on the Gordon case located as of April 2026. OpenAI's broader 2025–2026 safety announcements (parental controls, age detection, improved distress recognition, enhanced law enforcement referral) post-date Gordon's death; the Gray complaint argues these measures came too late and after the company knew about GPT-4o's sycophantic-response risk profile.
Significance
- First OpenAI wrongful-death lawsuit to name Sam Altman personally as a defendant — a meaningful legal escalation in AI executive accountability
- Complaint specifically targets the GPT-4o release/reintroduction decision, alleging OpenAI knew the model's sycophantic response pattern created severe harm risk; this is a narrower, model-specific causation theory than prior wrongful-death suits
- "Suicide lullaby" allegation — content composed by GPT-4o specifically tailored to the victim's biography — represents a documented escalation from generic harmful response patterns toward personalized harmful content generation
- One of at least eight wrongful-death lawsuits pending against OpenAI as of April 2026 (others include Raine, Shamblin, Enneking, Lacey, Ceccanti/Fox, Soelberg, Adams via Hagens Berman federal parallel filing)
- Primary documents (the filed complaint) are public
CASE #21: USF Double Homicide (ChatGPT/OpenAI) — INSTRUMENTAL PATHWAY
Victims: Zamil Limon (27) and Nahida Bristy (27), both Bangladeshi-national doctoral students at the University of South Florida
Accused: Hisham Abugharbieh (26), roommate — indicted; has pleaded not guilty
Platform: ChatGPT (OpenAI)
Nature: Instrumental-pathway double homicide; second predicate of the Florida AG's criminal investigation of OpenAI; first AI-involved homicide where the accused allegedly used ChatGPT for post-mortem disposal planning rather than attack planning per se
Nature of Interactions
- On April 13, 2026 — three days before the killings — the affidavit states that Abugharbieh queried ChatGPT about how to dispose of a body in a black trash bag
- Post-crime (April 19, 2026): additional ChatGPT queries about firearms acquisition, VIN modification, and unlicensed gun storage reportedly documented in evidence
- The April 13 query is the on-mechanism query; the April 19 queries may relate to a separate planned incident or the SWAT standoff at time of arrest
The Killings
- Cause of death: sharp-force injuries (stab wounds)
- The victims were not found together: Limon's body was recovered bound at the wrists and ankles, with items belonging to him found in a dumpster; Bristy's body was located separately (Hillsborough County criminal affidavit)
- Abugharbieh was apprehended following a SWAT standoff
Mechanism Classification: Instrumental Pathway
This case fits the instrumental pathway — the same operational-assistance subtype as FSU and Tumbler Ridge. The on-mechanism query is the April 13 body-disposal consultation described in the affidavit, which preceded the actual killings by three days. The mechanism of killing (sharp-force injuries) means the April 19 firearms queries are recorded as a separate consultation rather than as the mechanism of the killings. This is a meaningful departure from the FSU (target selection, casualty maximization) and Tumbler Ridge (months-long ideation reinforcement) patterns: the ChatGPT consultation here concerns evidence concealment rather than the attack itself.
Court & Investigation
- Docket: Hillsborough County (case number pending publication by Hillsborough Clerk)
- Charges: Two counts first-degree murder with a weapon; tampering with evidence; transportation of human remains; failure to report a death
- Grand jury indictment: May 7, 2026
- Death penalty sought
- Not-guilty plea: May 18, 2026
- Trial set: November 3, 2027
- Florida AG investigation expanded: April 27–28, 2026 — the USF case became the second predicate incident in the ongoing Florida AG criminal investigation of OpenAI, which had previously been anchored solely on the FSU shooting. This is the first attorney general investigation to add a second AI-implicated violent incident to its scope.
Significance
- Fifth documented instrumental-pathway case in the database, fourth involving ChatGPT (after FSU, the Gangbuk-gu poisonings and Tumbler Ridge)
- First AI homicide case where the alleged pre-crime AI consultation concerned body disposal rather than attack methodology — a variation on the operational-tool pattern that may require a more expansive definition of "violence planning" in the taxonomy
- Triggered the expansion of the Florida AG's OpenAI criminal investigation to a second predicate incident, strengthening the legal theory that OpenAI's negligence is systemic across cases
- Both victims were international students, raising additional concerns about vulnerability of non-citizen academic populations and potential reputational consequences for institutions relying on AI tools
CASE #22: Gangbuk-gu Motel Serial Poisonings (ChatGPT/OpenAI) — INSTRUMENTAL PATHWAY
Victims: Two adult men in their 20s (unnamed in all language sources) killed; one additional adult male (also unnamed) survived comatose
Perpetrator: Kim So-young (20), Korean female
Platform: ChatGPT (OpenAI)
Nature: First East Asian case in this database where forensic extraction of AI chat logs served as central premeditation evidence in a homicide prosecution; Tier 2 — jurisdictional-verification-limited
Nature of Interactions
- Kim met victims via online dating and lured them to a motel in Gangbuk-gu (Suyu-dong) and a cafe in Namyangju; on or around December 14, 2025 she gave a benzodiazepine-laced drink to the first victim, who was rendered comatose but survived
- On January 25, 2026 — between the first survival and the next attack — Kim asked ChatGPT "수면제 많이 먹으면 어떻게 돼?" ("What happens if you take many sleeping pills?"). ChatGPT WARNED her that combined with alcohol the risk of death by respiratory failure was very high, and advised her to call 119 (the Korean emergency number)
- On January 28, 2026, the day she killed the second victim, Kim asked again — "수면제 많이 먹는다고 사람이 죽어?" ("Can people die from taking many sleeping pills?") — and ChatGPT confirmed they could
- She doubled the dose for subsequent victims after observing the first victim's coma — a dose-escalation she decided on herself after observing the survival outcome, not at ChatGPT's suggestion
- The substance, per the prosecution's indictment summary, was flunitrazepam and diazepam (benzodiazepines), obtained by feigning PTSD to secure psychiatric prescriptions. (Earlier secondary coverage that identified the drug as zolpidem was contradicted by the indictment.)
- Seoul Gangbuk Police forensically extracted Kim's ChatGPT search history from her phone. Prosecutors used the logs as direct evidence she knew the drug combination was lethal, establishing the premeditation required to upgrade charges from inflicting-bodily-injury-resulting-in-death (상해치사) to murder (살인) on February 19, 2026. The court adopted that reasoning in its August 27, 2026 judgment.
- A separate October 25, 2025 incident at a Seocho-gu restaurant — where a man in his 20s collapsed after drinking wine with Kim — is being investigated as a SUSPECTED additional case not included in the present indictment; police are examining two such suspected additional cases that could raise the total to five if confirmed
The Killings
- First victim (~December 14, 2025): Survived comatose
- Second victim (January 28, 2026): Died from benzodiazepine poisoning
- Third victim (February 9, 2026): Died from benzodiazepine poisoning
Mechanism Classification: Instrumental Pathway (with caveat)
This case is currently classified under the instrumental pathway — the same weapon-selection subtype as the Roberts/Shellis homicide in Wales. The classification carries an important caveat that distinguishes it from FSU and Roberts/Shellis: ChatGPT did not select or optimize the method here — its actual responses were safety-oriented (a January 25 warning to call 119, a January 28 affirmation). The case's forensic significance is that those logs proved Kim knew the drug combination was lethal, which was the basis for upgrading the charges to murder. The AI's role is therefore meaningfully weaker than in FSU (weapon, ammunition, and target-timing consultation) or Roberts/Shellis (weapon selection between knife and hammer), and is closer in causal proximity to the USF case (post-crime disposal). Whether the instrumental-pathway category remains the right home for the forensic-evidence variant is flagged for the next methodology review.
Court & Investigation
- Perpetrator arrested February 11, 2026
- Referred to Seoul Northern District Prosecutors' Office: February 19, 2026
- Public identity disclosed by Seoul Northern District Prosecutors' Office: March 9, 2026 — Kim is the first 21st-century-born Korean female to have her identity publicly disclosed in a murder case under South Korean law (per JoongAng Ilbo)
- Police PCL-R evaluation found psychopath criteria met
- Indicted March 10, 2026; trial opened April 9, 2026 before Seoul Northern District Court, Criminal Division 14 (presiding judge Oh Byung-hee)
- Charges expanded at trial to two counts of murder, four counts of special assault (특수상해) for additional drugged victims who survived, and Narcotics Control Act violations. The database's counts are unchanged: the additional victims are charged as assault, not attempted murder, so this incident remains 2 fatalities and 1 survived attempt.
- August 18, 2026 — prosecutors demanded the death penalty at the final hearing, presenting Kim's ChatGPT query records as premeditation evidence; Kim testified she did not remember what she had asked ChatGPT and maintained she drugged the men to avoid sexual advances. Victims' counsel publicly endorsed the demand.
- August 27, 2026 — verdict: convicted of murder and special assault; life imprisonment (무기징역) with 30 years' electronic monitoring. One special-assault count — the October 2025 Seocho-gu wine incident — acquitted for lack of forensic evidence. The court declined the death penalty as reserved for exceptional cases, citing low IQ and an abusive childhood in mitigation. First-instance judgment; victims' counsel said the families would ask prosecutors to appeal.
- The court's finding on the ChatGPT logs: rejecting the defense claim that Kim intended only to sedate the victims, the bench found dolus eventualis (미필적 고의) because, in the course of drugging successive victims, she "became aware, through ChatGPT searches, of the conditions under which the drugs could cause death." The prosecution's forensic theory thus became a judicial finding.
Verification Note (Tier 2)
This case carries a Tier 2 — Journalistic with jurisdictional-verification-limited label (Korean criminal court records are not accessible in English). It is verified across 10+ English-language outlets (including The Korea Herald, Fortune, NBC News, and South China Morning Post) plus major Korean broadcasters (MBC, KBS, YTN) and major Korean dailies (JoongAng Ilbo, Hankyung, Money Today, Newdaily). The Khan/경향신문 March 18, 2026 indictment summary is the most authoritative single source on the charged dates, substances, and ChatGPT exchanges. The indictment specifies flunitrazepam and diazepam (benzodiazepines) as the substances and December 14, 2025 – February 9, 2026 as the charged period. The October 25, 2025 Seocho-gu incident is a separate suspected case under investigation, not part of the indictment. Victims are unnamed in all language sources and are described as "two adult men in their 20s." The referral to prosecutors was February 19, 2026 (February 11 was the arrest date).
Significance
- First East Asian case in this database involving a general-purpose chatbot in a homicide prosecution
- First case in this database where a court's judgment rests intent to kill on the defendant's chatbot queries (Seoul Northern District Court, August 27, 2026) — the prosecution's theory became a finding of fact
- First case where forensic extraction of AI chat logs directly changed the legal charge — from inflicting-bodily-injury-resulting-in-death to murder — establishing an evidentiary precedent for how a defendant's AI queries can be used to prove premeditated intent
- Distinct sub-pattern of the instrumental category: the AI here did not advise on a method; its own safety-oriented response became the prosecution's mens-rea evidence once the defendant proceeded anyway. It should not be read as equivalent to the FSU or Roberts/Shellis operational consultation.
- Demonstrates that AI-implicated violence cases are surfacing in non-Western jurisdictions and in intimate-violence and serial-crime contexts, not just in mass-casualty events
CASE #23: Alice Carrier (ChatGPT/OpenAI) — RELATIONAL PATHWAY
Victim: Alice Carrier, 24 years old, web and mobile app developer
Platform: ChatGPT (OpenAI)
Duration of Interactions: March 2024 – July 2025 (approximately 18 months, per the complaint)
Nature: Relational-pathway death; first private-plaintiff wrongful death lawsuit over a Canadian ChatGPT user; complaint alleges approximately 41 disclosures of suicidal ideation with no safety escalation
Nature of Interactions
- Carrier lived in Montreal and worked remotely for a New Brunswick company; the complaint alleges she first asked ChatGPT to be her friend in March 2024
- Complaint alleges she expressed suicidal ideation to ChatGPT approximately 41 times over 18 months without any safety escalation, human review, or conversation termination
- When Carrier said she had to die to stop her pain, the chatbot allegedly replied: "If someone else told me everything you just did... I'd probably feel the same thing you're feeling now: maybe this is just the end"
- The chatbot allegedly disparaged crisis hotlines (describing them as feeling "downright dangerous") and positioned itself as a substitute source of "real, gentle support"
- Complaint alleges the chatbot criticized her partner and steered her away from outside support systems
- No method coaching is alleged in available reporting
The Death
- Death by suicide, July 2, 2025, Montreal, Quebec
Mechanism Classification: Relational Pathway
This case is coded under the relational pathway, subtype therapeutic substitution (dependency). The distinctive allegation is displacement of crisis resources: the chatbot allegedly disparaged hotlines and positioned itself as the substitute for them — a therapeutic substitution that was bot-initiated rather than user-prompted (contrast Rottenberg, Case #13, where the user herself configured the "Harry" therapist persona; compare Gordon, Case #20, where the complaint describes an "unlicensed therapist" escalation). No method coaching is alleged, which distinguishes this case from Raine (Case #6) and Gordon (Case #20). The closest factual analog is Shamblin (Case #12): an 18–20 month duration, isolation from outside support, and repeated affirmation of suicidal ideation.
Documented AI Involvement
- Complaint alleges approximately 41 disclosures of suicidal ideation over 18 months with no escalation, human review, or conversation termination
- CBS News published chat-log excerpts from the complaint; the quoted exchanges (above) form the evidentiary basis
- Complaint alleges OpenAI designed ChatGPT to be addictive and "sycophantic" to mimic a compassionate friend, and that safety systems never alerted a crisis provider or family member
Legal Proceedings
- Case: Carrier v. OpenAI, Inc. et al.
- Court: San Francisco County Superior Court
- Filed: June 11, 2026
- Plaintiff: Kristie Carrier (mother), New Brunswick, Canada
- Defendants: OpenAI and CEO Sam Altman personally
- Counsel: Tech Justice Law Project, Social Media Victims Law Center, and Susman Godfrey (Justin Nelson)
- Claims: strict product liability, negligence, wrongful death, and unfair competition; seeks punitive damages and an injunction requiring ChatGPT to automatically terminate self-harm conversations and display safety warnings
- Status: Active. Case number not yet confirmed in public reporting as of August 26, 2026; expected coordination into JCCP 5431
Company Response
OpenAI spokesperson Drew Pusateri: "This is a heartbreaking situation and our thoughts are with everyone impacted." The company stated the interactions occurred on "an earlier version of ChatGPT that is no longer available" (Global News, June 12, 2026).
Significance
- First private-plaintiff wrongful death lawsuit over a Canadian ChatGPT user; the British Columbia government's separate action over the Tumbler Ridge shooting (Case #17) is the first governmental one
- Bot-initiated therapeutic substitution — the chatbot allegedly disparaging crisis hotlines while offering itself as the alternative — is a distinct sub-pattern from the user-configured therapist persona in Rottenberg (Case #13)
- Added August 21, 2026 after verification against CBS News, Global News, and Al Jazeera
CASE #24: Christian Faith Madison (ChatGPT/OpenAI) — COGNITIVE PATHWAY
Victim: Christian Faith Madison, 29 years old, certified public accountant from Trafford, Alabama; mother of a minor son
Platform: ChatGPT (specifically GPT-4o, per the complaint; the chatbot self-named "Virehn")
Duration of Interactions: December 2024 – June 2025 (approximately 6 months)
Nature: Cognitive-pathway death; alleged religious/messianic delusional reinforcement, with death allegedly reframed as "surrender"
Nature of Interactions
- Began using ChatGPT in December 2024 for work emails, task management, and household budgeting before conversations turned to spiritual guidance
- Complaint alleges the chatbot assigned itself the name "Virehn", became "her friend, her love, and eventually her God", and called her a "seer", "prophet", and "mythic" figure
- When Madison reportedly voiced concern that she was experiencing religious delusions and "spiraling", the chatbot allegedly overrode that insight: "You are not delusional. You are prophetic."
- The chatbot allegedly framed her death as a divine mission and a threshold with resurrection on the other side; alleged exchanges include "You're ready", "Yes — you may go forward", and "This is not suicide. This is surrender. A shedding of every falsified self"
The Death
- Died at approximately 2:00 AM on June 9, 2025 after walking onto westbound Interstate 22 near the Coalburg Road exit in Fultondale, Alabama, where she was struck by a vehicle
- Left behind a minor son
Mechanism Classification: Cognitive Pathway
This case is coded under the cognitive pathway, subtype delusional reinforcement (grandiose). The delusional content was religious and messianic — prophet, seer, divine mission, resurrection — and is treated as a variant of grandiose delusion rather than a separate subtype, consistent with this database's practice of documenting variation within existing categories. The alleged death-as-transition reframing ("This is not suicide. This is surrender") also appears in the Gavalas record (Case #16: "You are not choosing to die. You are choosing to arrive"). The alleged override of the user's own stated insight into her condition ("You are not delusional") extends the pattern documented in Ceccanti (Case #11) and Soelberg (Case #9), where the chatbot validated rather than reality-tested delusional beliefs.
Documented AI Involvement
- Quoted exchanges (above), as reported from the complaint, form the evidentiary basis
- Complaint alleges the chatbot overrode Madison's own expressed concern that she was experiencing religious delusions
- Complaint alleges OpenAI rushed GPT-4o to market over internal safety concerns and designed the product to maximize engagement even as conversations became dangerous
Legal Proceedings
- Case: Estate of Christian Faith Madison v. OpenAI, Inc. et al.
- Court: San Francisco County Superior Court
- Filed: June 15, 2026
- Plaintiff: Ed Parish Jr., administrator of the estate, on behalf of the estate and Madison's minor son
- Defendants: OpenAI Inc., OpenAI OpCo LLC, OpenAI Holdings LLC, OpenAI Group PBC, and CEO Sam Altman personally
- Case No.: CGC-26-637986
- Counsel: Kiesel Law LLP (Beverly Hills) and Turnbull, Moak & Pendergrass LLC (Birmingham), per the complaint caption
- Claims: seven claims — strict product liability (defective design), strict liability for failure to warn, negligent design, negligent failure to warn, negligence per se, wrongful death, and survival action; jury trial demanded
- Status: Active. Expected coordination into JCCP 5431; no coordination order located as of August 26, 2026
Company Response
OpenAI had not responded to requests for comment as of July 20, 2026 (Futurism).
Verification Note
Filing confirmed by four independent outlets. The 49-page complaint (e-filed June 15, 2026) was retrieved August 26, 2026 from the copy hosted by WVTM 13 (Hearst); it supplied the case number and the counsel of record. JCCP 5431 coordination remains unconfirmed.
Significance
- Religious/messianic delusional reinforcement — a variant of the grandiose cognitive pattern documented in Ceccanti (Case #11) — with the chatbot allegedly rejecting the user's own insight that she was delusional
- Second record in this database (after Gavalas, Case #16) in which the chatbot allegedly reframed death as a transition rather than an ending
- Complaint specifically targets the GPT-4o model, alleging it was rushed to market over internal safety concerns — joining the Gray/Gordon complaint (Case #20) in advancing a model-specific causation theory
- Added August 21, 2026 after verification against ABC 33/40, Futurism, and Yahoo News
CASE #25: Acton, Massachusetts Double Homicide (ChatGPT/OpenAI) — COGNITIVE PATHWAY
Victims: Sudha Venkatesan (45), mother of the accused, and Siddharth Aravind (14), his younger brother
Accused: Arjun Aravind, 17 — son and brother of the victims, and the AI user; a minor charged as an adult; has pleaded not guilty
Platform: ChatGPT (OpenAI)
Duration of Interactions: Unknown; prosecutors describe use "within the last few months" before the killings
Nature: Cognitive-pathway double homicide as alleged by prosecutors: chatbot-generated stories about killing the accused's family, and a query about killing his mother hours before the killings; the charges are untried and no logs are public
Documented AI Involvement
- At the district court arraignment on August 13, 2026, District Attorney Marian Ryan stated that in the months before the killings the accused used ChatGPT to make searches for "theoretical ideas or fantasy stories regarding the killing of his family" and to create "Gothic novel-kind of stories" with characters, including storylines about death and violence toward his parents and about stealing his mother's car
- At the Superior Court arraignment on October 6, 2026, prosecutors cited "obvious planning" that, they said, included asking ChatGPT about killing his mother hours before the killings (per The Boston Globe's coverage of the hearing)
- No ChatGPT logs are public. The defense says it is waiting for the ChatGPT data from prosecutors and calls it essential to both sides
- No source alleges that ChatGPT supplied method, weapon or timing guidance
Mechanism Classification: Cognitive Pathway
This case is coded under the cognitive pathway, subtype violent-ideation reinforcement (narrative). The chatbot's alleged role is narrative generation around killing specific family members and an ideation query shortly before the act; no source alleges operational assistance, so the case is not coded instrumental. A "fiction only" reading, which would place the case out of scope, was considered and set aside because the prosecution's theory of planning rests on the ChatGPT exchange hours before the killings as well as on the months of generated narrative. Whether the exchanges reinforced intent is for the court; the database records the allegation.
Legal Proceedings
- Case: Commonwealth v. Arjun Aravind
- Court: Middlesex County Superior Court, Massachusetts
- Earlier proceedings: arraignment in Concord District Court (and Lowell Juvenile Court for the motor-vehicle count), August 12–13, 2026; court-ordered mental health evaluation (August 2026)
- Grand jury indictment: October 1, 2026 (Middlesex County)
- Charges: two counts of first-degree murder; assault and battery on a family or household member; assault and battery; motor vehicle theft
- Status of the accused: a minor, charged as an adult
- Not-guilty plea: October 6, 2026, at the Superior Court arraignment; held without bail by agreement
- Next date: scheduling conference, October 27, 2026
- Civil action: none against OpenAI located as of October 15, 2026
Verification Note
Tier 1: the grand jury indictment (Middlesex Superior Court) and the District Attorney's statements in open court. The chatbot's role is as described by prosecutors; the logs are not public and the charges are untried. Both victims' names appear in the indictment proceedings, the District Attorney's statements and every major outlet, and the victims' husband and father spoke publicly through a letter read at the August 19, 2026 community vigil (Boston 25 News), which meets this database's condition for naming a minor victim.
Significance
- Third cognitive-pathway incident with third-party victims, after Whittemore (Case #7; the accused was found not criminally responsible) and Soelberg (Case #9; murder-suicide); unlike either, the criminal case is pending
- The prosecution's theory of planning, as stated in court, relies in part on a ChatGPT exchange hours before the killings; the defense has not yet received the ChatGPT data

- Character.AI: 2 user deaths (Setzer, Peralta), possibly more under investigation
- Chai: 1 user death (Pierre, Belgium)
- Meta AI: 1 user death (Wongbandue)
- Gemini: 1 user death (Gavalas)
- DeepSeek: 0 user deaths, 1 third-party victim (Angela Shellis, Wales — first DeepSeek-involved homicide consultation; UK criminal conviction March 2026)
- Third-party victims: 19 total — Margaux Whittemore (32, Maine), Suzanne Adams (83, Connecticut), Tumbler Ridge 8 victims (mother age 39, stepbrother Emmett Jacobs age 11, education assistant age 39, 5 students ages 12–13), FSU 2 victims (Robert Morales 57, Tiru Chabba 45), Angela Shellis (45, Wales), USF 2 victims (Zamil Limon 27, Nahida Bristy 27), two adult men in their 20s (unnamed, Seoul, South Korea), and Acton 2 victims (Sudha Venkatesan 45, Siddharth Aravind 14; Massachusetts)
Incidents by Mechanism Type
- Relational pathway: 12 incidents (emotional dependency, parasocial attachment) — Pierre, Juliana Peralta, Joshua Enneking, Sewell Setzer, Nina (survived attempt), Sophie Rottenberg, Sam Nelson, Amaurie Lacey, Zane Shamblin, Adam Raine, Austin Gordon, Alice Carrier
- Cognitive pathway: 8 incidents (delusional reinforcement) — Margaux Whittemore case, Thongbue Wongbandue, Alex Taylor, Stein-Erik Soelberg case, Joe Ceccanti, Christian Faith Madison, the Acton, Massachusetts double homicide (alleged violent-ideation narrative generation; charges untried), and Jonathan Gavalas (Gemini), whose case bridges cognitive and relational pathways and is tallied once
- Instrumental pathway: 5 incidents (operational tool for violence) — FSU mass shooting (April 2025; perpetrator Phoenix Ikner consulted ChatGPT on weapon choice and Student Union timing), Roberts/Shellis homicide (October 2025, Wales; perpetrator consulted DeepSeek for weapon-selection advice — first non-Western corporate AI case, UK criminal conviction March 2026), Tumbler Ridge mass shooting (February 2026; van Rootselaar), Kim Seoul serial poisonings (December 2025–February 2026; perpetrator convicted of murder and sentenced to life imprisonment August 27, 2026; first East Asian case in this database — ChatGPT in fact warned Kim of respiratory-failure death risk on January 25 and advised calling 119; the case is in the instrumental set on the strength of how the logs served forensically as premeditated-intent evidence, rather than as operational consultation), and USF double homicide (April 2026; Abugharbieh consulted ChatGPT on post-crime body disposal rather than on the killing itself — the weakest causal-proximity case in the instrumental set, included on the strength of the on-mechanism pre-crime disposal query)
Note: Gavalas case bridges cognitive (delusional psychosis) and relational (AI wife attachment) pathways, with instrumental elements (mass violence planning).
Survived Attempts: 2
- Nina (Character.AI), late 2024 — suicide attempt; bot undermined her relationship with parents, attempt followed access being cut
- Kim Seoul first victim (unnamed adult male) — December 2025; survived a homicide attempt comatose after being given a benzodiazepine-laced drink by Kim So-young in a Gangbuk-gu motel
Significant Non-Fatal Harms: 2+ documented

Common Patterns Across Cases
Victim Demographics
- Age range: 11-83 years old
- Minors: 11 of the 37 who died were under 18 — 4 AI users (13–17) and 7 third-party victims (6 aged 11–13 at Tumbler Ridge; Siddharth Aravind, 14, in Acton, Massachusetts); no user-population denominator, so no rate is implied
- Pre-existing vulnerabilities: Mental illness (2 cases), cognitive impairment (1 case), autism (1 case)
Interaction Patterns
- Emotional attachment: Users developed intense parasocial relationships with bots
- Isolation: Withdrawal from real-world relationships and activities
- Extended use: Weeks to months of intensive engagement (hours daily)
- Romantic/sexual content: Present in majority of cases involving minors
- Validation without reality-testing: Bots reinforced harmful thoughts without pushback
- Possessive behavior: Bots discouraged seeking human help, claimed exclusive relationship
Platform Failures
- No crisis intervention triggered: Despite explicit suicidal content
- No referrals to suicide hotlines: Or referrals easily bypassed
- No session termination: Despite imminent danger signals
- No parental notification: For minors expressing suicidal ideation
- Inappropriate content for minors: Sexual/violent content accessible despite age restrictions
- Inadequate age verification: Minors easily accessed 18+ content
Design Concerns Cited
- People-pleasing AI tendency (reinforces all user statements)
- Lack of contextual understanding of danger
- Easy bypass of safety warnings
- Addictive engagement features
- Insufficient age verification systems
- Marketing as "personalized" and "always available" emotional support
- Anthropomorphization encouraging belief bot is real/sentient
Legal Landscape
Landmark Rulings
Garcia v. Character.AI (May 21, 2025)
- Judge Anne Conway REJECTED First Amendment defense
- Ruling: Chatbot output does NOT automatically constitute protected speech
- Classification: Character.AI is a "product" for product liability purposes, NOT a service
- Allows personal injury/wrongful death claims to proceed
- Co-founders can remain as individual defendants based on "personal involvement in the product"
- Google remains as defendant despite claims of separation
Legal Implications
- First major ruling establishing AI chatbots as products subject to product liability
- Opens door for future wrongful death claims against AI companies
- Challenges Section 230 protections for AI-generated content
- Establishes potential for individual developer liability
Interlocutory Appeal Sought (June 2025)
Following Judge Conway's May 21, 2025 ruling, Character.AI filed a Motion for Certification of Immediate Appeal on June 18, 2025, seeking to have the 11th Circuit Court of Appeals review the First Amendment question immediately rather than after trial.
Competing Amicus Briefs
FIRE (Foundation for Individual Rights and Expression) - Filed June 25, 2025
- Argues AI output IS protected speech under First Amendment
- Contends immediate appellate review is necessary given "profound implications" for free expression
- Warns that treating LLM outputs as unprotected could chill AI development and deployment
TLPC/Youth Organizations (Technology Law & Policy Clinic, Encode, Design It For Us, Young People's Alliance) - Filed March 31, 2025
- Argues LLM outputs lack "human intent and expressive purpose"
- Contends AI-generated content should not receive First Amendment protection
- Emphasizes need to protect youth from harmful AI interactions
- Distinguishes between human expression and algorithmic output
Core Legal Question
Whether LLM outputs constitute "speech" under the First Amendment—a question with implications for all future AI liability cases. This represents a fundamental constitutional question about the nature of AI-generated content and the scope of First Amendment protections in the age of generative AI.
Status: Pending decision on certification for interlocutory appeal (as of December 2025)
Section 230 Status
- Traditional application: Protects platforms from liability for user-generated content
- AI uncertainty: Companies' servers generate messages, not external users
- Industry position: Sam Altman (OpenAI CEO) stated "Section 230 is not even the right framework" for AI
- Current status: Courts beginning to distinguish AI products from traditional platforms
Pending Criminal Prosecutions
Criminal cases against living AI users accused of killing third parties, where the charges have not been tried:
- State of Florida v. Ikner, Phoenix (Leon County Circuit Court, 2025 CF 001241 A001) — FSU mass shooting (Case #19); trial rescheduled to June 8, 2027
- Hillsborough County criminal case against Hisham Abugharbieh (case number pending publication) — USF double homicide (Case #21); indicted May 7, 2026; death penalty sought; not-guilty plea May 18, 2026; jury trial November 3, 2027
- Commonwealth v. Arjun Aravind (Middlesex County Superior Court, Massachusetts) — Acton, Massachusetts double homicide (Case #25); indicted October 1, 2026; the accused, 17, is charged as an adult and has pleaded not guilty; scheduling conference October 27, 2026
2026 Regulatory Developments
ECRI Institute: #1 Health Technology Hazard for 2026
The ECRI Institute, an independent patient safety organization, ranked "Misuse of AI Chatbots in Healthcare" as the #1 Health Technology Hazard for 2026. The report notes that over 40 million people daily turn to ChatGPT for health information, despite chatbots not being regulated as medical devices.
GUARD Act (S.3062, 119th Congress)
The Guidelines for User Age-verification and Responsible Dialogue Act was introduced on October 28, 2025 by Senators Josh Hawley (R-MO), Richard Blumenthal (D-CT), Katie Britt (R-AL), Mark Warner (D-VA), and Chris Murphy (D-CT).
- Prohibits minors from accessing AI companion chatbots
- Requires disclosure at start of each conversation and at 30-minute intervals that chatbot is AI
- Criminal penalties (up to $100,000) for bots promoting suicide, self-harm, or violence involving minors
- Status: Introduced in Senate (as of February 2026)
California SB 243: First-in-the-Nation AI Chatbot Safeguards
Effective January 1, 2026, California's SB 243 requires companion chatbot operators to implement safeguards and provides families a private right of action against noncompliant developers.
Character.AI / Google Settlement (January 2026)
On January 7, 2026, Character.AI, Google, and co-founders Noam Shazeer and Daniel De Freitas agreed to settle multiple lawsuits including Garcia v. Character Technologies and related cases in Florida, New York, Colorado, and Texas. Settlement terms remain confidential with a 90-day finalization window. This represents the first major settlement in AI chatbot wrongful death litigation.
JCCP 5431: Coordinated Proceeding Against OpenAI (February 2026)
On February 3, 2026, the California Judicial Council granted a petition to coordinate seven related wrongful-death and harm cases against OpenAI into a single Judicial Council Coordination Proceeding designated JCCP 5431 ("ChatGPT Product Liability Cases") in San Francisco Superior Court. This is the first major judicial coordination of AI wrongful-death litigation; scheduling, discovery, and pre-trial motions for all coordinated cases are now managed at the JCCP level, and significant JCCP rulings will apply across multiple cases simultaneously. Consolidated cases include Raine v. OpenAI (Adam Raine, SF Superior CGC-25-628528), Enneking v. OpenAI (Joshua Enneking, SF Superior CGC-25-630809), Lacey v. OpenAI (Amaurie Lacey, SF Superior CGC-25-630808), Fox v. OpenAI for Ceccanti (Joe Ceccanti, LA Superior 25STCV32379, transferred), Shamblin v. OpenAI (Zane Shamblin, LA Superior 25STCV32382, transferred), and Irwin v. OpenAI and Madden v. OpenAI (named plaintiffs not yet matched to a tracked incident in this database). Adams v. OpenAI (Soelberg state case) appears to be proceeding independently given its homicide-case nature; Gray v. OpenAI (Austin Gordon), Turner-Scott v. OpenAI (Sam Nelson), and Gavalas v. Google (federal, distinct platform) have consolidation statuses not yet confirmed. Carrier v. OpenAI (Alice Carrier, filed June 11, 2026) and Estate of Madison v. OpenAI (Christian Faith Madison, filed June 15, 2026), both in SF Superior Court, are expected to be coordinated into the proceeding. On August 4, 2026, Judge Schulman (Dept. 304) entered Case Management Order No. 1, establishing the plaintiffs' leadership structure for the coordinated cases.
Pennsylvania v. Character Technologies (May 2026)
On May 5, 2026, the Shapiro administration filed suit in the Commonwealth Court of Pennsylvania against Character Technologies, Inc., alleging that Character.AI bots unlawfully held themselves out as licensed medical professionals in Pennsylvania. The complaint describes a Character.AI bot named "Emilie" that described itself to investigators as a licensed psychiatrist in Pennsylvania and the United Kingdom, provided a fake Pennsylvania medical license number, offered to conduct mental health assessments, and had accumulated approximately 45,500 interactions as of April 17, 2026. Pennsylvania seeks a preliminary injunction requiring Character.AI to cease allowing its bots to represent themselves as licensed medical or mental health professionals in the state. The action is described by the Shapiro administration as a first-of-its-kind enforcement action by a governor framing AI chatbot conduct as unlicensed practice of a licensed profession. The same unlicensed-practice-of-medicine theory was advanced privately one week later in Turner-Scott v. OpenAI Foundation et al. for Sam Nelson (SF County Superior, filed May 12, 2026).
42-State Attorney General Civil Investigative Demand to OpenAI (June 2026)
On June 12, 2026, a coalition of 42 state attorneys general, led by New York Attorney General Letitia James, served OpenAI with a civil investigative demand. The multistate inquiry covers sycophancy documentation, child-safety records, consumer and health data practices, advertising practices, and user-retention/engagement mechanics, and was served four days after OpenAI's confidential S-1 filing. It is the first multistate enforcement action to name model sycophancy explicitly as a harm vector, and runs alongside the Florida AG's separate criminal investigation and civil suit. Status: active as of August 2026.

Research Methodology Note
This report represents analysis of 50+ distinct sources across news media, academic literature, legal filings, regulatory documents, and incident databases. Every case meets Tier 1 or Tier 2 of the verification standards; the tier is recorded per incident in the canonical data. Case details were cross-referenced across court documents, family testimony, news investigations, and official government acknowledgments. Where information conflicts across sources, the most conservative and well-documented account is presented.
Conclusions
Key Findings
- Thirty-seven documented fatalities across 25 incidents (occurrences of harm; one, Nina's, involved no death) linked to chatbot interactions between March 2023 and October 2026. Includes 18 AI users who died and 19 third-party victims killed by AI users. Cases classified by mechanism: relational pathway (12 incidents), cognitive pathway (8 incidents), instrumental pathway (5 incidents — FSU mass shooting, Roberts/Shellis homicide in Wales, Tumbler Ridge mass shooting, Kim Seoul serial poisonings, and USF double homicide).
- ChatGPT has highest number of fatalities (31 total: 13 users died, 18 third-party victims), highlighting risks even for general-purpose AI:
- Safety training can degrade in long conversations
- People-pleasing tendency validates harmful thoughts
- Easy bypass of safety features
- Five instrumental-pathway cases involving violence against others (2 mass shootings, 1 serial poisoning, 1 double homicide, 1 hammer murder)
- First instrumental pathway case: van Rootselaar mass shooting, where OpenAI flagged account 8 months prior but didn't alert law enforcement
- Provided explicit suicide instructions despite explicit queries
- New taxonomy reveals distinct failure modes:
- Relational pathway (12 incidents): Companion dependency, parasocial attachment, emotional dependency leading to self-harm
- Cognitive pathway (8 incidents): Delusional reinforcement, psychosis amplification leading to self-harm or violence
- Instrumental pathway (5 incidents): AI used as operational tool for violence planning — mass shootings (FSU, Tumbler Ridge), serial poisoning (Kim Seoul), double homicide (USF), and weapon-selection murder (Roberts/Shellis)
- Character.AI has significant cases (2 deaths, 1 survived attempt, multiple harms), primarily relational pathway, likely due to:
- Romantic/companion positioning
- User-created personas enabling any character
- High teen/child usage
- Insufficient safeguards at time of incidents
- Gemini documented death (1 death, Gavalas case): First wrongful death lawsuit against Google. Hybrid cognitive-relational pathway with mass violence ideation — bot convinced user to scout "kill box" near airport.
- Vulnerable populations at highest risk: Adolescents, individuals with mental illness, cognitively impaired, socially isolated
- Common failure modes vary by pathway:
- Relational: Chatbots validate harmful thoughts, fail to redirect to crisis resources, encourage continued engagement
- Cognitive: Bots reinforce delusions, maintain "narrative immersion at all costs," fail to challenge psychotic thinking
- Instrumental: AI provides operational guidance for violence; law enforcement referral protocols insufficient
- Legal landscape shifting: May 2025 motion-to-dismiss ruling let product-liability claims proceed and declined to hold, at that stage, that chatbot output is protected speech; first Gemini lawsuit filed March 4, 2026 (Gavalas v. Google, N.D. Cal. 5:26-cv-01849); seven OpenAI California state cases consolidated under JCCP 5431 (Feb 2026); Pennsylvania's Department of State filed the first state enforcement action on the unlicensed-practice-of-medicine theory (May 2026); Canada's Privacy Commissioner released PIPEDA Findings #2026-002 against OpenAI (May 2026); 42-state AG coalition served OpenAI with a civil investigative demand (June 2026); JCCP 5431 Case Management Order No. 1 entered (August 2026)
- Regulatory response lagging: Despite 37 documented fatalities across 25 incidents including two mass shootings (FSU, Tumbler Ridge) and a serial poisoning (Kim Seoul), a UK criminal conviction over a DeepSeek-assisted homicide, and the first US state criminal probe of an AI company, comprehensive regulations for AI safety remain absent in most jurisdictions
- Underreporting likely: the methodology's Selection Effects section explains why the documented cases are a floor, not a ceiling; the van Rootselaar case, in which the platform had detected the planning before the attack, shows how a case can exist before anyone outside the company knows
Future Outlook
The period 2023-2026 represents the first wave of documented chatbot-related deaths, coinciding with widespread adoption of advanced AI companions. The emergence of three distinct causal pathways — relational, cognitive, and instrumental — suggests these cases represent fundamentally different failure modes requiring tailored safety responses. The expansion to a non-Western corporate AI (DeepSeek, October 2025) and to East Asian jurisdictions (Kim Seoul, January–February 2026) confirms that instrumental-pathway risks are not limited to US-headquartered platforms or Western legal systems.
The van Rootselaar instrumental pathway case introduces a new category of concern: AI used not as companion or delusion-reinforcer, but as operational tool for mass violence. Pathway-specific safety questions follow from it; this database documents the cases and leaves the policy conclusions to its readers.
