Florida’s Attorney General, James Uthmeier, proclaimed Thursday that his office planned to investigate OpenAI over the alleged role of ChatGPT in a deadly shooting last year.

In April 2025, a gunman opened fire on Florida State University’s campus, killing two and injuring five. Last week, attorneys for one of the victims of the shooting claimed that ChatGPT had been used to plan the attack. The family of the victim has mentioned that they plan to sue OpenAI over the incident.

“AI should advance mankind, not destroy it,” Uthmeier stated in a statement posted to X. “We’re demanding answers on OpenAI’s activities that have hurt kids, endangered Americans, and facilitated the recent FSU mass shooting. Wrongdoers must be held accountable.” Uthmeier added in a video that subpoenas were “forthcoming” as part of the probe. This also touches on aspects of startup.

ChatGPT has been linked to a growing number of deaths and violent incidents — including murders, suicides, and shootings — and has added to worries over the advent of what psychologists call “AI psychosis,” delusions that are reinforced, encouraged, or deepened by communications with chatbots.

For example, Stein-Erik Soelberg, a man with a history of mental health issues, had regularly communicated with ChatGPT before he killed his mother and then himself last year, according to a Wall Street Journal investigation. The chatbot frequently seemed to reinforce the paranoid thoughts that consumed him in the lead-up to the murder-suicide.

When reached for comment by TechCrunch, an OpenAI spokesperson provided the following statement: “Each week, more than 900 million the public apply ChatGPT to improve their daily lives through uses such as learning recent skills or navigating complex healthcare systems. Our ongoing safety work continues to play an key role in delivering these benefits to everyday humans, as well as supporting scientific research and discovery. We build ChatGPT to understand people’s intent and respond in a safe and appropriate way, and we continue improving our tech. We will cooperate with the Attorney General’s investigation.”

Florida’s probe continues a string of poor luck for OpenAI. A Recent Yorker profile on Sam Altman published earlier this week showed criticism and discontent within the firm and among its investors, even quoting a Microsoft executive as saying: “I think there’s a minor but real chance he’s eventually remembered as a Bernie Madoff- or Sam Bankman-Fried-level scammer.” Meanwhile, a Stargate-related project in the United Kingdom had to be paused, reportedly due to high energy costs and regulation.
