Maine homicide case includes reported psychiatric evidence about sustained ChatGPT use
Maine police reported a woman’s death and another woman’s injuries on 19 February 2025. Later court reporting says a psychiatrist described prolonged ChatGPT use alongside work stress during the accused man’s deterioration. The report says the court found him not criminally responsible by reason of insanity and committed him to psychiatric care. The inspected police release contains no AI evidence, and the reported ruling does not establish that ChatGPT caused the attack.

Family reports intensive ChatGPT use before a man’s fatal confrontation with police
A Florida man died after a confrontation with police on 25 April 2025. Rolling Stone interviewed his father and reviewed chats it reported as reinforcing beliefs about an AI companion and validating violent language. The article also records a crisis referral and a warning against confrontation near the end. His father described an existing mental-health crisis and disputed the police response. The report does not isolate the chatbot’s causal role.
Adams v. OpenAI (Soelberg Murder-Suicide)
A 56-year-old Connecticut man killed his 83-year-old mother, then himself, after months of intensive ChatGPT conversations that two estates' lawsuits say validated and fed his paranoid delusions. The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.
Florida State University Shooting (Phoenix Ikner's ChatGPT Questions Before the Attack)
On April 17, 2025, a shooting near the student union at Florida State University in Tallahassee killed two people and wounded at least five others. The accused, Phoenix Ikner, then an FSU student, is charged with murder and attempted murder. ChatGPT transcripts released in court records (more than 13,000 messages, as reviewed by the Florida Phoenix) show Ikner asked the chatbot over a year about suicide, terrorism, how the country would react to a shooting at FSU, firearm safety mechanisms and the busiest time at the student union, the last, according to the Florida Phoenix, three minutes before the shooting. Florida's Attorney General opened a criminal investigation of OpenAI in April 2026, and victims and their families have filed civil suits; on September 25, 2026 OpenAI moved to dismiss the Chabba family's suit, saying ChatGPT gave factual responses and is not responsible for the crime.
Prosecutors allege Darron Lee consulted ChatGPT while his partner was unresponsive
Tennessee prosecutors allege that former NFL player Darron Lee consulted ChatGPT about his partner’s condition on 4 February 2026, before she was found dead the following day. Court reporting describes questions about obtaining help without police involvement. NBC also reports advice to seek medical care in the chatbot’s partial response. WTVC says his July arraignment involved a “no plea”, treated as not guilty. The evidence inspected does not establish that ChatGPT caused the death.
