A U.S. law firm representing survivors of the Tumbler Ridge mass shooting is filing 30 lawsuits against OpenAI, alleging the tech giant was negligent in not reporting the shooter’s chat history to police in an effort to help prevent the attack.

Three new lawsuits, filed Wednesday in U.S. federal court in California, name OpenAI CEO Sam Altman and accuse the company of having a double standard when it comes to safety. The firm intends to file 30 in total.

The suits, one for each plaintiff, allege the company notified law enforcement immediately about threats against its own staff but allegedly withheld potentially life-saving information about the Tumbler Ridge shooter’s violent chat history before the shooting.

The suits also allege ChatGPT was allowed to continue chats with users on violent subjects in order to boost engagement, which allegedly facilitated the chats that allowed the shooter to plan her attack.

Jesse Van Rootselaar, 18, killed eight people in the northern B.C. community in February before killing herself in one of the deadliest mass shootings in Canadian history. Before entering the town’s school, she killed her mother and 11-year-old half-brother in their family home.

The 30 new lawsuits add to seven others launched in April on behalf of victims who were killed. The new lawsuits claim the company knew the shooter posed a significant threat, but allegedly avoided alerting police before the attack because doing so would force the company to create an internal system for reporting other violent users to the authorities.
