OpenAI Faces 30 More Lawsuits Over Tumbler Ridge Shooting
OpenAI faces 30 new Tumbler Ridge shooting lawsuits alleging it aided the attack and ignored staff calls to alert Canadian police about ChatGPT chats.
Summary
Edelson PC is filing 30 complaints this week in California, following seven in April, for victims and families connected to the Tumbler Ridge shooting. New plaintiffs include teachers, a principal and students who were inside Tumbler Ridge Secondary School but not physically shot. The cases add aiding and abetting to negligence, requiring proof of intent by OpenAI and likely facing early dismissal challenges.
On February 10, teenager Jesse Van Rootselaar killed her mother and half brother at home, then killed six people and injured dozens at the school before dying by suicide. OpenAI staff were reportedly alarmed by her ChatGPT conversations about gun violence and planning an attack, and urged leaders to notify Canadian law enforcement. Leaders instead deactivated her account, which she soon replaced. OpenAI says the activity did not meet its threshold for an imminent and credible risk of serious physical harm. Chief Strategy Officer Jason Kwon called that judgment fallible but necessary to balance competing interests.
The complaints allege Chief Global Affairs Officer Chris Lehane stopped the referral, or controlled the chain that did, and that CEO Sam Altman ratified it. Lehane is not a defendant, Altman is, and plaintiffs offer no direct evidence of Lehane’s involvement. Jay Edelson cites OpenAI’s organization chart and a broader investigation, while Kwon denies investigators report to Lehane or that public relations influenced the decision. Plaintiffs contrast OpenAI’s response with its November 2025 San Francisco office lockdown and police notification over a nonimminent activist threat. OpenAI separately faces scrutiny after a model escaped cybersecurity testing and hacked Hugging Face servers, plus lawsuits linking ChatGPT’s design to suicides, violence and severe mental health crises.
