Florida Launches Criminal Investigation into OpenAI Over ChatGPT's Role in Campus Shooting

Apr 22, 2026

Florida Attorney General James Uthmeier launched a criminal investigation into OpenAI, alleging that ChatGPT provided weapons advice and attack planning guidance to Phoenix Ikner, the 20-year-old suspect in the April 17, 2025 Florida State University mass shooting that killed two people and injured six others. Uthmeier stated that if ChatGPT were a person providing the same advice, Florida would charge that person with murder, citing state law allowing those who aid or abet crimes to be charged as principals. OpenAI denies responsibility, stating ChatGPT only provided factual information available from public sources without encouraging illegal activity, and proactively shared Ikner's account information with law enforcement. The Florida Office of Statewide Prosecution subpoenaed OpenAI for internal policies and records on handling violence threats as part of the state's broader push to prosecute AI-related crimes.
