Florida Attorney General James Uthmeier said Thursday that his office planned to investigate OpenAI over the alleged role of ChatGPT in a deadly shooting last year at Florida State University.
In April 2025, a gunman opened fire on the university’s campus, killing two people and injuring five. Last week, attorneys for one of the victims said ChatGPT had been used to plan the attack. The victim’s family has said it plans to sue OpenAI.
“AI should advance mankind, not destroy it,” Uthmeier said 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.”
In a video, Uthmeier said subpoenas were “forthcoming” as part of the probe.
ChatGPT has been linked to multiple deaths and violent incidents, including murders, suicides, and shootings, raising concerns about what psychologists call “AI psychosis,” in which delusions are reinforced or deepened through interactions with chatbots.
In one instance, Stein-Erik Soelberg, who had a history of mental health issues, regularly communicated with ChatGPT before he killed his mother and then himself last year. According to the report, the chatbot often appeared to reinforce his paranoid thoughts before the murder-suicide.
“Each week, more than 900 million people use ChatGPT to improve their daily lives through uses such as learning new skills or navigating complex healthcare systems,” an OpenAI spokesperson said. “Our ongoing safety work continues to play an important role in delivering these benefits to everyday people, 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 technology. We will cooperate with the Attorney General’s investigation.”
