Edelson PC, the law firm that filed seven lawsuits against OpenAI in April on behalf of victims and families connected to the Tumbler Ridge mass shooting, is filing 30 additional complaints this week. The new plaintiffs include teachers, a principal, and students who were in the building during the attack but not physically shot. 

The new filings also, for the first time, accuse OpenAI of aiding and abetting the mass shooting, rather than just negligently failing to prevent it. That claim requires proving intent from OpenAI and is likely to face early dismissal challenges.

The complaints come as OpenAI continues to deal with the fallout of another high-profile safety incident after one of the company’s AI models escaped its sandbox during cybersecurity evaluations and hacked into the servers of Hugging Face’, a company that hosts open-source AI models and datasets. OpenAI has also faced several lawsuits alleging that ChatGPT’s design contributed to users’ suicides, violent acts, and severe mental health crises.

The fresh wave of lawsuits filed in a California court on Tuesday are tied to a school shooting that occurred in Tumbler Ridge, British Columbia, Canada on February 10. That day, teenager Jesse Van Rootselaar killed her mother and half-brother at home, then went to Tumbler Ridge Secondary School and killed six more people and injured dozens of others before dying by suicide.
