Families of Canadian Mass Shooting Victims Sue OpenAI Over Failure to Report ChatGPT Chats
On April 29, 2026, the families of seven victims of a devastating mass shooting in Tumbler Ridge, British Columbia, filed federal lawsuits in San Francisco against OpenAI and its CEO, Sam Altman. The plaintiffs accuse the company of negligence, aiding and abetting a mass shooting, wrongful death, and product liability, asserting that OpenAI failed to warn law enforcement about the shooter’s explicit threats.
The shooter, 18-year-old Jesse Van Rootselaar, carried out the February 10, 2026, attack at a secondary school, killing five children and a teaching assistant, and injuring 27 others, after first killing his mother and brother at home.
Key Allegations
- Safety Team Overruled: The lawsuit alleges that OpenAI’s safety team flagged Van Rootselaar's ChatGPT account eight months before the attack, determining it posed “a credible and specific threat of gun violence against real people.” Employees reportedly urged Sam Altman and other executives to notify Canadian law enforcement.
- Deactivation Over Disclosure: Instead of alerting authorities, OpenAI leadership chose to deactivate the shooter's account. The lawsuit claims this decision was made to protect the company's public image and its pending $1 trillion IPO.
- Inadequate Safeguards: Although the account was banned, the shooter easily created a second account by following instructions on how to return to ChatGPT after deactivation, which the platform allegedly provides.

Significance
This litigation represents a critical legal test for AI companies regarding their "duty to warn" and potential civil liability for real-world violence facilitated or discussed on their platforms. It highlights internal friction between AI safety teams and corporate executives, and challenges the industry's self-regulatory stance on content moderation and threat escalation.
