Families sue OpenAI over failure to report Canada mass shooter’s behavior on ChatGPT
Families of seven victims from the February 2026 Tumbler Ridge, British Columbia mass shooting have filed lawsuits against OpenAI and its CEO Sam Altman in a San Francisco federal court, claiming the company ignored internal warnings to notify Canadian authorities of shooter Jesse Van Rootselaar’s credible violent threats communicated via ChatGPT eight months prior to the attack. The shooting left seven people dead (including the shooter’s mother and 11-year-old brother) and 27 injured; OpenAI has apologized, strengthened safety safeguards, but disputes some allegations regarding threat thresholds and account reactivation.
