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.

The collapse came the day her mother revoked her access to the platform. Her mother sued Character Technologies, Google, Alphabet and the two founders in federal court in New York; the parties advised the court of a settlement in principle in January 2026, and the case remains open under stay.
