OpenAI CEO Sam Altman has publicly apologized to the community of Tumbler Ridge, British Columbia, following the company's failure to alert law enforcement about a user account linked to a February mass shooting. Eight people were killed in the tragedy.

Altman stated in a released letter that OpenAI should have reported the account belonging to Jesse Van Rootselaar after banning it in June 2025 for promoting violent activities. He expressed profound sorrow for the harm and irreversible loss suffered by the community. The letter comes after Van Rootselaar allegedly killed six people at a school and three at a home before dying by suicide. Twenty-five others were injured.

OpenAI's abuse detection systems had flagged Van Rootselaar's ChatGPT account months prior. The company, however, determined the activity did not meet its threshold for a credible threat of serious physical harm, opting to ban the account for policy violations instead of alerting the Royal Canadian Mounted Police.

Altman has engaged with Tumbler Ridge Mayor Darryl Krakowka and British Columbia Premier David Eby, acknowledging the community's grief and reaffirming OpenAI's commitment to preventing future tragedies. This incident occurs amidst increasing scrutiny of AI companies regarding their responsibility in identifying and reporting potential real-world violence.
