B.C. Sues OpenAI Over Tumbler Ridge School Shooting Warning
British Columbia alleges OpenAI failed to warn police about ChatGPT conversations linked to the Tumbler Ridge school shooting.

British Columbia has sued OpenAI and chief executive Sam Altman in California, accusing the company of failing to warn police about violent ChatGPT conversations linked to the Tumbler Ridge school shooting. The province says the February attack might have been prevented if OpenAI had referred the user’s activity to law enforcement.
OpenAI says it remains committed to working with governments and police, but the lawsuit argues that the company’s internal safety process identified warning signs and still failed to trigger an alert. The Guardian reported that the lawsuit was filed in San Francisco federal court on Monday, September 21. It seeks damages for recovery costs and an order requiring changes to how OpenAI handles conversations that could lead to violence.
The case sets up a direct conflict over who should decide when violent online behavior crosses the threshold for police intervention: OpenAI’s safety teams, or public authorities operating under legal standards outside the company.
British Columbia targets OpenAI’s reporting decision
The province’s lawsuit says OpenAI’s safety team flagged the shooter’s conversations about gun violence in June 2025. According to the claim, members of that team recommended contacting police, but Altman and other senior OpenAI leaders overruled the recommendation.
OpenAI deactivated the account, but the user was able to create another account and continue using the platform, the lawsuit says. British Columbia argues that the company had information that could have helped investigators intervene before the attack and did not pass it on.
The lawsuit also alleges that Altman later apologized to the Tumbler Ridge community and promised reforms, but did not follow through despite efforts by the province’s attorney general to engage with the company.
Nine people were killed in the Tumbler Ridge shooting
The attack took place on February 10, 2026, in Tumbler Ridge, a small community in northeastern British Columbia. The Guardian reported that nine people, primarily children, were killed in the school shooting.
Police details cited in the report said the 18-year-old shooter first killed her mother and stepbrother at home, then killed an educational assistant and five students aged 12 and 13 at her former school before dying by suicide. The school victims therefore included six people: one educational assistant and five students.
The provincial government says it is absorbing costs tied to the attack, including mental-health services and the replacement of the school building. The damaged school is being demolished, adding a physical reconstruction bill to the longer-term costs borne by the community.
British Columbia’s lawsuit follows more than 30 cases brought in California by family members of victims and others affected by the shooting. Those cases accuse OpenAI of failing to act on information that could have helped prevent the attack.
OpenAI says the case involves an “unspeakable tragedy”
Drew Pusateri, an OpenAI spokesperson, described the shooting as an “unspeakable tragedy” and said the company remains committed to working with government and law-enforcement officials.
“OpenAI remains committed to working collaboratively with government and law enforcement officials, and continuing to advance our ongoing safety work.”

OpenAI has denied the broader claims in litigation over ChatGPT and violence. The company says its systems are trained to refuse requests that could meaningfully enable violence and that it notifies law enforcement when conversations indicate an imminent and credible risk of harm to others.
After a Wall Street Journal investigation examined the Tumbler Ridge account, OpenAI said its systems had identified misuse connected to violent activity. The company also said the conversations did not meet its internal criteria for reporting to police.
The lawsuit asks a court to impose new safeguards
British Columbia is not seeking only compensation. Its complaint asks the court to direct OpenAI to change how it manages conversations that may signal planned violence, placing the company’s internal reporting standards under judicial scrutiny.
The province’s action also arrives as OpenAI faces other lawsuits involving alleged harms linked to ChatGPT. In June, Florida sued the company over claims that its platform exposed children to safety risks, including information useful to school shooters and guidance related to self-harm. OpenAI has denied those allegations.
The California case will now test whether a province can hold a US-based AI company financially responsible for the consequences of a decision not to contact police about a user’s activity. The immediate dispute concerns OpenAI’s warning process, the Tumbler Ridge victims, and the costs of replacing a school where nine people were killed in the shooting.
