OpenAI CEO Sam Altman has publicly apologized to the community of Tumbler Ridge, B.C., for not alerting police about internally flagged usage of ChatGPT involving gun violence by shooter Jesse Van Rootselaar prior to the Feb. 10 mass killing.
In an April 23 apology letter published on the local news website Tumbler RidgeLines, Altman says he regrets his company not contacting Canadian authorities after Van Rootselaar’s account was banned in June 2025.
