Families of Canadian mass shooting victims sue OpenAI, CEO Altman in US court

Families allege OpenAI ignored warning signs in ChatGPT chats and failed to alert police, as lawyers seek jury trials in more than two dozen cases.

  • Seven families filed lawsuits against OpenAI and CEO Sam Altman in a California court on Wednesday, accusing the company of negligence in the Tumbler Ridge mass shooting that killed eight people in February.
  • OpenAI safety staff flagged Jesse Van Rootselaar's account for "gun violence activity and planning" in June 2025, yet leadership chose to deactivate the account instead of alerting the Royal Canadian Mounted Police despite internal urging.
  • On February 10, Van Rootselaar killed eight people, including six children, at Tumbler Ridge Secondary School; a complaint for 12-year-old Maya Gebala alleges the shooter "continued using ChatGPT to plan the attack" after creating a second account.
  • An OpenAI spokesperson stated the company has a "zero-tolerance policy" and has "already strengthened our safeguards," while Justice Minister Sean Fraser told officials the government expects changes or will intervene.
  • Lawyer Jay Edelson expects to file more than two dozen legal actions with jury trials anticipated next year, aiming to hold OpenAI leadership accountable for prioritizing company interests over public safety.
