Lawsuits Filed in San Francisco
On April 29 2026, seven families of Tumbler Ridge victims filed complaints in U.S. District Court for the Northern District of California, naming OpenAI and CEO Sam Altman for alleged negligence and failure to alert police about the shooter’s flagged ChatGPT interactions.
Background & Context
Eighteen-year-old Jesse Van Rootselaar killed her mother and half-brother at home, then entered Tumbler Ridge Secondary School, killing five students and a teacher before committing suicide. The attack ranks among Canada’s deadliest school shootings.
Timeline
OpenAI flagged the account in June 2025; its safety team urged RCMP notification, but leadership declined. The shooting occurred on Feb 10 2026. Lawsuits were filed Apr 29 2026, and Altman apologized in April, followed by a blog on safeguards.
Data & Statistics
Reports list nine deaths (including the shooter) or eight victims, and at least 25 injured, including 12-year-old Maya Gebala with severe head and neck wounds. Plaintiffs cite OpenAI’s pending $1 trillion IPO as a motive for silence.
Official Statements & Responses
OpenAI’s spokesperson said company has a zero-tolerance policy for using its tools to aid violence and has strengthened safeguards, including detecting repeat violators and mental-health referrals. A blog post adds that OpenAI notifies law enforcement when conversations show an imminent, credible risk. Altman’s open letter expressed regret for not alerting police, noting words “can never be enough.”
Criticism & Opposition
Jay Edelson says OpenAI “did the math and decided the safety of the children … was an acceptable risk,” tying the decision to the upcoming IPO. John Rice calls the attack “specific, predictable, and preventable.” Tim Marple calls the behavior “incompetence and greed,” Eric Goldman warns that strict regulation could curb free speech.
Conflicting Reports & Gaps
Media differ on whether nine or eight victims died and on how the shooter created a second ChatGPT account after the first was deactivated. The content of the second account remains undisclosed, and OpenAI has declined to release the chat logs.
Why It Matters
The lawsuits test whether AI firms can be liable for user-generated content that precipitates violence and intensify calls for mandatory reporting and broader AI regulation, echoed by Canadian AI minister Evan Solomon and Florida Attorney General James Uthmeier’s criminal probe.
What’s Next
Edelson plans to file two dozen more suits. Regulators in Canada and the United States are reviewing the case, and OpenAI faces a criminal investigation in Florida.
