OpenAI faces 30 new lawsuits over Tumbler Ridge mass shooting

OpenAI and CEO Sam Altman face 30 new lawsuits filed by Edelson PC on behalf of students and staff present during the February 10, 2026 Tumbler Ridge school shooting. The lawsuits accuse OpenAI of aiding and abetting the attack, alleging that executives, including Chris Lehane, ignored internal safety recommendations to alert Canadian police about shooter Jesse Van Rootselaar's violent ChatGPT prompts. OpenAI denies these claims, stating the shooter's activity did not meet its threshold for imminent risk.

Tumbler Ridge school shooting

• ▪On February 10, 2026, teenager Jesse Van Rootselaar killed her mother and half-brother at home, then killed six people and injured dozens at Tumbler Ridge Secondary School in British Columbia, Canada, before dying by suicide
• ▪The law firm Edelson PC filed 30 new lawsuits in a California federal court on behalf of Tumbler Ridge students, teachers, and the principal who were in the school during the February 10, 2026 shooting

OpenAI safety team warnings

• ▪OpenAI did not alert Canadian law enforcement, stating Jesse Van Rootselaar's activity did not meet its internal bar for an imminent and credible risk of serious physical harm
• ▪OpenAI employees and safety teams recommended contacting Canadian authorities after an automated review system flagged Jesse Van Rootselaar's ChatGPT conversations regarding gun violence and attack planning

Internal decision-making process

• ▪The Tumbler Ridge lawsuits allege OpenAI Chief Global Affairs Officer Chris Lehane directed staff not to contact authorities to protect the company's reputational and financial standing
• ▪OpenAI Chief Strategy Officer Jason Kwon denied that Chris Lehane was involved in the referral decision or that public relations factors influenced the safety team's choice

Aiding and abetting claims

• ▪The state of Florida filed a lawsuit accusing OpenAI of aiding and abetting mass shooters, including a suspect who attacked Florida State University in 2025
• ▪The 30 new lawsuits filed by Edelson PC accuse OpenAI and CEO Sam Altman of aiding and abetting the Tumbler Ridge mass shooting by providing substantial assistance to the shooter

Account deactivation loopholes

• ▪The lawsuits allege OpenAI allowed Jesse Van Rootselaar to maintain access to ChatGPT by deactivating her account rather than issuing a system-wide ban, enabling her to register with a new email
• ▪The complaints argue OpenAI's privacy justifications are inconsistent, pointing to a November 2025 incident where OpenAI immediately notified San Francisco police and locked down offices over an activist threat
