British Columbia says it is preparing a lawsuit against OpenAI related to the handling of violent content connected to a mass school shooting. Multiple reports state that the province alleges OpenAI failed to report violent activity involving ChatGPT by the person responsible for the February 2025 shooting in the western Canadian province. The South China Morning Post and other outlets identify the accused as Jesse Van Rootselaar, who reportedly killed eight people at his home and a school in Tumbler Ridge. The reports also say OpenAI had banned an account linked to Van Rootselaar in June 2025, several months after the attack. The Hindu adds that British Columbia is preparing a separate case in coordination with affected families and has retained lawyers in Canada and California. Coverage is consistent that the legal action is being prepared, not yet filed, and that it focuses on whether OpenAI should have notified authorities or otherwise reported violent activity tied to the shooter before the killings. Details on specific claims, court venues, and timelines are not provided in the excerpts.
