British Columbia sues OpenAI over Tumbler Ridge school shooting
The lawsuit claims OpenAI failed to warn authorities about the shooter's use of ChatGPT. Over 30 families have also filed separate suits. The case highlights growing legal scrutiny of AI's role in violence.

British Columbia has filed a lawsuit against OpenAI, alleging the company failed to alert local law enforcement that the shooter used ChatGPT to plan a mass shooting at a school in the province. The lawsuit, filed in San Francisco federal court, names OpenAI and its CEO, Sam Altman, as defendants. It seeks damages to cover the province’s recovery costs from the February attack and demands changes to how the company handles similar risks in the future.
The lawsuit follows a tragic incident in which Jesse Van Rootselaar, then 18, shot her mother and stepbrother at home before killing an educational assistant and five students aged 12 to 13 at her former school on February 10. Van Rootselaar later died by suicide. British Columbia’s attorney general, Niki Sharma, stated that in any other circumstance where a person aids, encourages, or conspires to commit a criminal offense or is criminally negligent, they can be investigated, prosecuted, and judged.
The province’s lawsuit comes after more than 30 family members of victims and others impacted by the attack filed separate lawsuits in California federal court. These suits accuse OpenAI of failing to take adequate measures to prevent the tragedy. The legal actions underscore a broader debate about the responsibilities of AI companies in mitigating risks associated with their platforms.
The case raises significant questions about the legal and ethical obligations of AI firms. If successful, the lawsuit could set a precedent for holding technology companies accountable for the misuse of their tools. It may also prompt regulatory changes, increase scrutiny of AI safety protocols, and influence how companies balance innovation with risk management. The outcome could have far-reaching implications for the AI industry and its relationship with law enforcement and the public.
The legal battle is expected to draw attention from courts, regulators, and the public, as it challenges the boundaries of liability for AI developers. The case may also influence future litigation involving AI and its role in criminal activities. As the trial progresses, the focus will remain on whether OpenAI’s actions—or inactions—constituted negligence in the face of a foreseeable risk.
