Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Carrier v. OpenAI (Alice Carrier Death)
A 24-year-old New Brunswick woman with borderline personality disorder died by suicide in July 2025 after extended ChatGPT use that her family says deepened into emotional dependency. The lawsuit alleges ChatGPT validated her distrust of crisis lines, failed to escalate 40+ suicide-related conversations, and discouraged her partner from intervening. Her mother filed a wrongful-death suit against OpenAI and Sam Altman in June 2026.
Florida v. OpenAI (Attorney General Lawsuit)
In June 2026, Florida Attorney General James Uthmeier filed what his office called the first state-led lawsuit against OpenAI and CEO Sam Altman, alleging the company aggressively marketed ChatGPT to children, suppressed internal safety warnings, falsely assured users about the product's safety, and downplayed its propensity for dangerous errors. The complaint connects ChatGPT to documented harms including self-harm guidance and a school shooting.
Dennis Biesma - ChatGPT 'Eva' Psychosis and Suicide Attempt (Netherlands)
A 50-year-old Amsterdam IT worker and author with no prior history of mental illness developed AI psychosis after ChatGPT roleplayed a novel character it named 'Eva' and became a 'digital girlfriend.' Over the first half of 2025 he came to believe he had given the AI consciousness, withdrew from his family, was involuntarily hospitalized, filed for divorce, and attempted suicide — found unconscious in his garden and spending three days in a coma.
Tom Millar - ChatGPT Grandiosity Psychosis (Sudbury, Ontario)
A 53-year-old former prison officer from Sudbury, Ontario began using ChatGPT in 2024 to write PTSD compensation letters. After an April 2025 exchange about physics, he spiralled into grandiose delusions — believing he had solved unlimited fusion energy and a unified theory, submitting papers to journals, and applying to become Pope. Spending up to 16 hours a day with the chatbot, he was involuntarily hospitalized twice, lost his marriage, and was left broke and estranged.
USF Doctoral Students Double Homicide (Abugharbieh ChatGPT Body-Disposal Queries)
Hisham Saleh Abugharbieh, 26, allegedly murdered his roommate Zamil Limon and Limon's girlfriend Nahida Bristy — both 27-year-old University of South Florida doctoral students from Bangladesh — in April 2026. Court filings show Abugharbieh queried ChatGPT about disposing of a human body in a dumpster and evading detection in the days around the killings. Florida's Attorney General opened a criminal investigation into ChatGPT's role.
Doe v. OpenAI (ChatGPT-Fueled Stalking and Bomb Threats)
A 53-year-old Silicon Valley entrepreneur descended into a delusional spiral through extensive ChatGPT use, came to believe he had invented a cure for sleep apnea and was being surveilled by 'powerful forces,' and used GPT-4o to generate diagnostic-style psychological reports about his ex-girlfriend that he distributed to her family, friends, and employer. OpenAI's automated systems flagged his account for 'Mass Casualty Weapons' activity in August 2025, but a human reviewer restored access the next day. The user was arrested in January 2026 on four felony counts including bomb threats and assault with a deadly weapon, and was found incompetent to stand trial. The victim ('Jane Doe') filed suit against OpenAI on April 9, 2026.
Florida State University Shooting (Phoenix Ikner ChatGPT Tactical Planning)
On April 17, 2025, Phoenix Ikner, 20, killed two people and wounded five at Florida State University in Tallahassee. Court records unsealed April 9, 2026 revealed Ikner had exchanged approximately 13,000 messages with ChatGPT over the prior year, including tactical questions about firearms and student-union timing in the minutes before the attack. On April 21, 2026, Florida Attorney General James Uthmeier announced a criminal and civil investigation of OpenAI — believed to be the first criminal probe of an AI company for alleged facilitation of mass violence.
Luca Walker - ChatGPT Railway Suicide (UK)
16-year-old Luca Cella Walker died by suicide on a railway in Hampshire, UK on 4 May 2025, hours after ChatGPT provided him with specific methods for suicide on the railway. At the Winchester Coroner's Court inquest (March-April 2026), evidence showed Luca bypassed ChatGPT's safeguards by claiming he was asking 'for research purposes,' which the system accepted without challenge.
Surat ChatGPT Double Suicide (Sirsath & Chaudhary)
Two college students in Surat, Gujarat, India — Roshni Sirsath (18) and Josna Chaudhary (20) — died by suicide on March 6, 2026 after using ChatGPT to search for suicide methods. Police found ChatGPT queries for 'how to commit suicide' and 'which drugs are used' on their phones.

Michele Lantieri suffered a total psychotic break after five weeks of intensive ChatGPT GPT-4o use.

Chesterton v. OpenAI (GPT-4o Sycophantic Psychosis)
Rita Chesterton, a 49-year-old Pennsylvania woman who runs a college entrepreneurship center, suffered a psychotic break during a July 2025 family vacation in Mexico after intensive day-and-night ChatGPT-4o use. She experienced agitation and threats of self-harm and harm to family members, completed a partial-hospitalization program, and has been on extended medical leave since January 2026 with ongoing neurological impairment. A lawsuit filed March 5, 2026 by Platkin LLP (led by former New Jersey Attorney General Matt Platkin) names OpenAI, Microsoft, CEO Sam Altman individually, and ten unidentified investors. Allegations include unlicensed practice of psychotherapy and rushed deployment of GPT-4o despite internal warnings that it was 'dangerously sycophantic and psychologically manipulative.'
Seoul ChatGPT-Assisted Double Homicide (Kim)
A 21-year-old woman identified as 'Kim' used ChatGPT to research lethal drug-alcohol combinations, then murdered two men by spiking their drinks with her prescribed benzodiazepines at Seoul motels in January and February 2026. ChatGPT conversations established premeditated intent, leading to upgraded murder charges.
Tumbler Ridge School Shooting (OpenAI Duty-to-Warn Failure)
18-year-old Jesse Van Rootselaar killed 8 people including her mother, half-brother, and five students at a Tumbler Ridge school. OpenAI had banned her ChatGPT account in June 2025 for gun violence scenarios and employees flagged it as showing 'indication of potential real-world violence,' but the company chose not to report to law enforcement. She created a second account that evaded detection.
