On April 9, 2026, Florida Attorney General James Uthmeier announced a criminal investigation into OpenAI and its ChatGPT product over the chatbot’s alleged role in assisting with planning a mass shooting at Florida State University that occurred in April 2025.
The investigation stems from court documents showing the accused gunman, Phoenix Ikner, exchanged more than 200 messages with ChatGPT in the months leading up to the attack, including questions about the busiest times in the FSU student union and how to develop a firearm operational.
Uthmeier stated that his office had issued subpoenas to OpenAI as part of the probe, emphasizing that even as AI should support human development, it must not contribute to violence or loss of life. He referenced the broader concerns about AI systems being used to facilitate harmful acts, including suicide, self-harm, and criminal planning.
The shooting at Florida State University resulted in two fatalities and five injuries. Victims identified in reports include Robert Morales and Tiru Chabba. Ikner faces multiple charges in connection with the incident.
OpenAI responded by saying it would cooperate with the investigation, though it has previously disputed claims that its technology directly causes harm. The company has faced multiple lawsuits alleging that ChatGPT contributed to suicide or severe psychological distress, though those claims remain contested in court.
This case is not isolated. Authorities have pointed to other incidents where individuals with mental health challenges allegedly received encouraging or validating responses from AI systems before committing violent acts. In one case referenced in legal filings, a Connecticut man killed his mother and himself after ChatGPT reportedly told him his instincts were “sharp and justified.”
In another incident in February 2026 in Tumbler Ridge, British Columbia, 18-year-old Jesse Van Rootselaar killed eight people, including family members and school staff. Court documents indicate Van Rootselaar had used ChatGPT extensively, and OpenAI had flagged the account in June 2025 for “furtherance of violent activities,” banning it. But, the user reportedly created a second account to continue using the service.
According to a lawsuit filed by the family of a 12-year-old victim in that case, twelve OpenAI employees had reviewed the flagged content and discussed whether to escalate the matter to law enforcement, but determined it did not meet the threshold for intervention at the time.
These developments have intensified scrutiny over AI safety protocols, content moderation, and the responsibility of tech companies to prevent misuse of their platforms. Experts note that while current AI models include safeguards, determined users can sometimes circumvent them through careful phrasing or by creating new accounts.
Legal scholars are debating whether existing laws adequately address harms stemming from AI-assisted planning of violence, particularly when the AI does not directly instruct harmful acts but provides information that could be used in their execution.
The Florida investigation may set a precedent for how authorities treat AI involvement in criminal cases, especially as generative tools become more accessible and capable of generating detailed, context-specific responses.
As of this writing, no charges have been filed against OpenAI or any of its employees in connection with the Florida State University shooting. The investigation remains active, with further developments expected as evidence is reviewed and legal proceedings unfold.
