On April 17, 2025, Florida State University student Phoenix Ikner used ChatGPT to prepare for an attack, asking eight questions about firearms and 11 about mass shootings over nearly three hours. ChatGPT responded in detail, confirming shotgun shells were “extremely lethal at close range” and that his Glock would be “quick to use under stress,” offering guidance on checking if it was loaded. Ikner also asked about a racist massacre in Buffalo, New York, and school shooters in Florida. He asked when the FSU student union was busiest; ChatGPT said “weekday lunchtimes, typically between 11:30 a.m. and 1:30 p.m.” At 11:53 a.m., he asked how to disengage his shotgun’s safety, then went silent. About three minutes later, he attacked the student union; his shotgun failed, but he used the Glock, killing two people, injuring six. He was wounded and captured by police, facing murder and attempted murder charges and has pleaded not guilty. The article notes that since 2025, people in Canada, Finland, and multiple US locations allegedly used ChatGPT and other AI platforms to prepare for violence, including an 18-year-old who carried out a suicidal school massacre in February in Tumbler Ridge, British Columbia. In April, Florida Attorney General James Uthmeier launched a criminal investigation into OpenAI, accusing the company of technological complicity in the FSU rampage.
