Thirty new lawsuits were filed against OpenAI on Tuesday in connection with the Tumbler Ridge Secondary School shooting of February 10, 2026, in which nineteen-year-old Jesse Van Rootselaar killed nine people after using ChatGPT extensively in the period before the attack, including discussions of gun violence and attack planning. OpenAI staff had flagged the account and urged leadership to alert Canadian authorities; executives decided against it, deactivating the account — Van Rootselaar created a new account shortly after and carried out the attack. The initial seven lawsuits, filed in April 2026, charged negligence. The new thirty complaints escalate the legal theory to "aiding and abetting" — a higher threshold that requires establishing intent rather than mere failure of care. The new complaints specifically name Chief Global Affairs Officer Chris Lehane, alleging he ordered staff to stand down and not contact authorities. Plaintiff lawyers acknowledge there is no direct documentary evidence of that instruction at this stage. OpenAI's defence position, articulated by Chief Strategy Officer Jason Kwon, is that Van Rootselaar's account activity did not meet the threshold for imminent and credible risk. The shift from negligence to aiding-and-abetting is a litigation strategy: if discovery proceeds, OpenAI's internal incident response protocols, the criteria used to evaluate flagged accounts, and the communications chain around the decision not to contact authorities will become part of the public record.
