Overview
- A U.S. law firm filed 30 new complaints on Wednesday that bring the total to about 37 separate suits in federal court in California and upgrade many claims from negligence to aiding-and-abetting.
- The suits say OpenAI’s automated systems flagged the shooter’s ChatGPT conversations in June 2025 and that an internal safety team recommended notifying Canadian police but leadership deactivated the account instead.
- Plaintiffs name senior figures including CEO Sam Altman and for the first time accuse Chris Lehane of overruling safety staff, while OpenAI denies the specific allegations about Lehane and defends its safety processes.
- Victims and survivors are demanding full production of the shooter’s chat logs, internal chain-of-command documents and injunctive relief to force operational changes at OpenAI.
- If courts allow the aiding-and-abetting theory to proceed it could broaden liability for AI companies, though that claim will face legal hurdles because it requires proof the company purposefully assisted the attacker.
