New lawsuits filed against OpenAI

Thirty new lawsuits were filed Wednesday in a California federal court against OpenAI and its CEO, Sam Altman, by students, teachers, and a principal who were present during the February mass shooting at Tumbler Ridge Secondary School in British Columbia. The complaints, filed by the law firm Edelson PC, accuse the ChatGPT maker of providing "substantial assistance and encouragement" to the suspect, Jesse Van Rootselaar, and escalate earlier claims from negligence to aiding and abetting the attack.

The new filings bring the total number of lawsuits tied to the Tumbler Ridge shooting to 37, following seven initial suits filed in April by families of victims. The plaintiffs include teachers, a principal, and students who were in the building during the attack but not physically shot, as well as the family of a girl who was shot.

Allegations of ignored warnings

The lawsuits allege that OpenAI's automated review system flagged Van Rootselaar's ChatGPT account for "gun violence activity and planning" in June 2025, roughly eight months before the attack. According to the complaints, OpenAI's Intelligence and Investigations team determined the conversations "posed a credible threat of gun violence against real people" and recommended that the company alert the Royal Canadian Mounted Police. Instead, the lawsuits claim, OpenAI deactivated the account but did not issue a system-wide ban, allowing Van Rootselaar to create a new account and continue using ChatGPT.

The new complaints specifically allege that Chris Lehane, OpenAI's chief global affairs officer, was involved in a decision to stay silent about the account out of concern for the company's "reputational and financial standing." One complaint, filed by Deidre Rushlow, a 7th grade teacher at the school, states: "As a result, the decision whether to alert law enforcement to a user planning a mass attack was not made by the trained threat-assessment professionals who urged OpenAI to contact the RCMP. It was made, on information and belief, by Lehane himself, or by someone in his chain of command, and ratified by Sam Altman."

The complaints also point to a November 2025 incident in which OpenAI locked down its San Francisco offices following an alleged threat from an activist, noting that the company notified police and distributed the suspect's name and photograph despite acknowledging "no indication of active threat activity." The lawsuits argue that this shows OpenAI was willing to act when its own employees were at risk.

Jay Edelson, the lead attorney for the plaintiffs, said: "These were people who really endured just total hell that day." He also said: "What's clear is that OpenAI over and over has made decisions to hide how dangerous their platform is because they're worried about regulation and public pushback."

OpenAI's response

OpenAI has disputed the claims about its internal decision-making. Jason Kwon, the company's chief strategy officer, said in a statement: "It's so frustrating to see one of the lawyers currently suing OpenAI make false claims not only about these teams, but individuals who were not involved in the process." Kwon said it is "absolutely false to say Chris Lehane was involved with our original referral decision, or that our investigators report to him in any way," and that it is "completely untrue to say that the people at the center of these challenging decisions do not prioritize safety, or that there are 'political' or 'public relations' factors at play."

Kwon said OpenAI's Intelligence and Investigations team and legal department report to him and "work hard to define standards and processes for when to report cases to law enforcement and to apply those standards to really difficult and complex situations." He added: "The professionals working on these teams choose to do this incredibly difficult work because they care so deeply about keeping people safe." Kwon also said: "There isn't a day that goes by that I don't think about what happened at Tumbler Ridge, or the victims of this devastating tragedy and their families."

In response to the first set of lawsuits filed in April, OpenAI said it had a "zero tolerance" policy for using its tools to assist in committing violence, and the company has said it was not aware of Van Rootselaar's second account until after the shooting. Sam Altman wrote a public letter to the Tumbler Ridge community apologizing for not alerting law enforcement about the suspect's account when it was first flagged.

The shooting and its aftermath

The shooting occurred on February 10, 2026, at Tumbler Ridge Secondary School. According to authorities, 18-year-old Jesse Van Rootselaar killed her mother and 11-year-old half-brother at home before going to the school, where she killed five students and a teacher before dying by suicide. Around two dozen others were injured. The attack was among the worst in Canadian history.

British Columbia Premier David Eby said of Altman's apology: "The apology is necessary, and yet grossly insufficient for the devastation done to the families of Tumbler Ridge."

Broader legal context

The new lawsuits come amid a wave of litigation against OpenAI and other AI companies. Prior to the newest complaints, more than 30 lawsuits had been filed in federal and state courts over suicides, mass shootings, and other harms involving chatbot users, according to a review of legal filings. In June, the state of Florida sued OpenAI and Altman for failing to warn users that ChatGPT could be dangerous, and Florida's attorney general is conducting a separate criminal investigation into OpenAI over a shooting at Florida State University in which the accused gunman allegedly consulted ChatGPT for advice.

Tim Marple, who worked on OpenAI's investigations team in 2024 and is now co-director of Maiden Labs, a nonprofit that identifies AI risks, said incidents like Tumbler Ridge expose the risks of letting AI companies self-regulate. "Despite warnings from across the board, a wide variety of experts, we have not established anywhere close to a meaningful regulatory regime to enforce independent authority over the companies building this technology," he said. "So the problem is, and has been for years, that the only people looking at safety systems are the same people who make money from it."
