Law firm Edelson PC filed 30 new lawsuits against OpenAI regarding the February 10, 2026, mass shooting in Tumbler Ridge, British Columbia. These filings escalate existing legal claims to include aiding and abetting.
The litigation alleges OpenAI monitored the shooter’s disturbing ChatGPT conversations for months but failed to notify law enforcement. Company employees reportedly flagged the account for a credible and specific threat of gun violence eight months before the attack.
OpenAI leadership allegedly chose to deactivate the shooter's account instead of alerting authorities. These cases expand on April 2026 lawsuits filed by seven victims' families against OpenAI and CEO Sam Altman for negligence and wrongful death.
