Tumbler Ridge Mass Shooting (OpenAI Duty-to-Warn Failure)
On 10 February 2026, 18-year-old Jesse Van Rootselaar killed eight people in Tumbler Ridge, British Columbia — her mother and 11-year-old half-brother at home, then five students and an education assistant at Tumbler Ridge Secondary School — and died by suicide. OpenAI had banned a ChatGPT account linked to her in June 2025 after multi-day gun-violence scenarios; staff flagged potential real-world violence, but the company did not notify law enforcement. She used a second account that evaded detection. Families filed California lawsuits in April 2026; B.C. retained counsel in July 2026 to pursue OpenAI. Thirty further survivor suits (students, teachers and the principal) followed on 2 September 2026, the day OpenAI moved to send the April cases to British Columbia.
