Lawsuits Filed in San Francisco
Seven suits were filed in federal court in San Francisco by relatives of victims and injured survivors of the Tumbler Ridge school attack. The complaints allege OpenAI and CEO Sam Altman ignored internal warnings that the shooter posed a credible threat eight months before the February 10, 2026 shooting. Plaintiffs seek damages and a court order requiring law-enforcement referrals.
Background of the February 10, 2026 Attack
Eighteen-year-old Jesse Van Rootselaar entered a secondary school in Tumbler Ridge, British Columbia, after killing her mother and half-brother at home. At the school she killed five students, a teaching assistant, and then herself. The attack left nine dead and about 27 injured.
Key Figures and Organizations
- Sam Altman – CEO, OpenAI
- Jesse Van Rootselaar – shooter
- Jay Edelson – lead plaintiff attorney
- OpenAI safety team – flagged shooter’s account
- Tim Marple – former OpenAI employee, now at Maiden Labs
- David Eby – Premier of British Columbia
Data and Statistics
Fatalities: nine, including the shooter. Injured: approximately 27, including 12-year-old survivor Maya Gebala. The shooter’s ChatGPT account was flagged in June 2025 for “gun-violence activity and planning.” OpenAI’s pending IPO is projected near $1 trillion.
Official Statements and Responses
OpenAI reiterated a zero-tolerance stance on using its tools for violence and announced safeguards, including better distress detection, mental-health referrals, and stricter escalation of threats. Altman apologized for not notifying law enforcement and pledged cooperation with authorities.
Criticism and Opposition
Tim Marple, a former OpenAI safety-team member, called the decision not to involve police “incompetence and greed.” Eric Goldman warned that regulation could curb free speech and questioned whether civil lawsuits are the proper tool for AI harms.
On-the-Ground Accounts
12-year-old survivor Maya Gebala was shot three times and remains in intensive care after four brain surgeries. A vigil featured a carved wooden memorial listing victims’ names, reflecting local mourning.
Conflicting Reports and Gaps
OpenAI’s internal memo says the flagged account did not meet its threshold for referral, while plaintiffs say the safety team recommended notification and leadership overruled it. The company has not released the full logs, leaving the content undisclosed.
