AI Incident Database: ChatGPT Was Alleged to Have Aided Planning of Florida State University Mass Shooting

On April 17, 2025, a shooting at Florida State University killed Tiru Chabba and Robert Morales and injured others. Phoenix Ikner, the accused shooter, has pleaded not guilty. In 2026, victims' families and attorneys reportedly alleged that Ikner used ChatGPT before the attack to discuss mass shootings, firearms, campus activity, and media attention, and that OpenAI failed to flag or escalate the exchanges. OpenAI denied responsibility.
