OpenAI faces 30 new lawsuits over ChatGPT's role in Tumbler Ridge shooting

Thirty new lawsuits filed in California

OpenAI and its CEO Sam Altman are facing 30 new lawsuits accusing the company of providing "substantial assistance and encouragement" to the suspect in Canada's Tumbler Ridge school shooting, according to The Verge, which cites earlier reporting by TechCrunch. The filings were made in a California federal court on Wednesday by students, teachers and the principal who were at the school when the attack took place.

The complaints echo an earlier wave of lawsuits brought by victims' families in April, which also centered on how OpenAI handled warning signs in the alleged shooter's use of ChatGPT.

What the lawsuits allege

According to The Verge, the plaintiffs claim OpenAI's automated review system flagged conversations between ChatGPT and the alleged shooter, Jesse Van Rootselaar, about gun violence. The company's safety team is said to have recommended contacting Canadian authorities, but the lawsuits allege a decision was made not to — a decision the filings say involved chief global affairs officer Chris Lehane and was driven by concern for OpenAI's "reputational and financial standing."

The suits also take issue with how OpenAI restricted the suspect's access. Rather than issuing a system-wide ban, the complaints allege, the company merely deactivated his account, leaving him free to sign up again with a different email address. The filings argue that keeping the tool within the shooter's reach amounted to substantial assistance on its own, and that this assistance was a key factor in enabling him to plan and carry out the attack.

OpenAI rejects the claims

Jason Kwon, OpenAI's chief strategy officer, responded publicly on X. As reported by The Verge, Kwon said the lawsuits contain "false claims" about the company's safety teams, and rejected the suggestion that the people making these decisions failed to prioritize safety or that political or public-relations considerations were involved.

The legal pressure on OpenAI extends beyond this case. The Verge notes the company is also being sued by the state of Florida, which accuses it of aiding and abetting mass shooters, including the suspect behind last year's attack at Florida State University.

Why it matters

These lawsuits press on a question courts have not yet settled: whether a company that builds and operates an AI chatbot can be held legally responsible for a violent act committed by one of its users. The Tumbler Ridge filings are notable because they do not merely argue that ChatGPT produced harmful content. They allege that OpenAI's own systems detected warning signs, that internal staff recommended escalation to law enforcement, and that the company declined to act — both by staying silent and by failing to block the suspect's return to the service.

If the plaintiffs succeed, even partially, the case could establish duties for AI providers that go well beyond content moderation: a duty to alert authorities when user conversations cross certain thresholds, and a duty to enforce bans that users cannot sidestep with a fresh email address. A ruling in OpenAI's favor would instead reaffirm that liability for such attacks rests with the perpetrator alone. Either outcome would shape how AI companies design their safety escalation pipelines, account verification and ban enforcement, and the overlap with Florida's separate suit suggests this is becoming a coordinated legal front rather than an isolated dispute.
