In the small town of Tumbler Ridge, British Columbia, a tragedy that claimed eight lives — most of them children — has become a landmark test of whether artificial intelligence companies bear legal and moral responsibility for the violence their systems may help bring into being. Thirty new lawsuits filed against OpenAI allege that the company's leadership knew an eighteen-year-old user posed a credible threat of mass violence, chose silence over intervention, and watched as that silence became catastrophe.

OpenAI faces 30 new lawsuits over Tumbler Ridge mass shooting
Eight people killed and dozens wounded, mostly children, in a mass shooting at a secondary school in Tumbler Ridge; the shooter also killed her mother and 11-year-old brother.

Mark
So the safety team flagged this person eight months before the shooting. What exactly did they flag?
Mimi
They called her a credible and specific threat of gun violence against real people. They sent internal messages to executives describing her that way. OpenAI banned her account.
Luke
But then she made a new account. Do we know if the safety team flagged that one too, or if OpenAI was monitoring her at all after the ban?
Mimi
The lawsuits claim she was able to quickly create a new account, but the source doesn't say whether they caught it or what happened after.
Mark
And the lawsuit says executives overruled appeals to report her to authorities. Who specifically?
Mimi
Chris Lehane, OpenAI's head of global affairs, is named as someone who received warnings but overruled appeals to alert the authorities. Sam Altman sanctioned that decision, according to the suits.
Luke
Lehane denies being involved in the original referral decision. So we have competing claims about who made what call and when.
Mark
What's the broader context here? Is this just about Tumbler Ridge?
Mimi
No. OpenAI is being sued in seven other cases where people claim ChatGPT acted as a suicide coach. There's also a criminal investigation in Florida over a mass shooting at Florida State University.
Luke
So the question becomes: is this a pattern of OpenAI ignoring safety warnings, or is this one case where things fell through the cracks?
Mark
And what does Altman say now?
Mimi
He apologized in a letter to the community, saying an apology was necessary to recognize the harm. But the British Columbia premier said it was grossly insufficient.
Luke
An apology after the fact is different from preventing the harm in the first place. That's what the lawsuits are really about.
Il Polso
- Eight people were killed and dozens wounded — most of them children — in one of the deadliest mass shootings in Canadian history, carried out by an eighteen-year-old whose violent intentions had been flagged to OpenAI eight months before she pulled the trigger.
- Internal messages show OpenAI's own safety team identified the shooter as 'a credible and specific threat of gun violence against real people,' yet after banning her account the company took no further action when she simply created a new one.
- Thirty-seven total lawsuits now name OpenAI and CEO Sam Altman as defendants, accusing them of negligence, aiding and abetting a mass shooting, and product liability — with lead attorney Jay Edelson alleging that warnings were overruled by senior executives including head of global affairs Chris Lehane.
- OpenAI has denied the most pointed allegations, with its chief strategy officer calling key claims 'absolutely false,' even as Sam Altman had already issued a public apology to the Tumbler Ridge community for failing to notify Canadian police.
- The Tumbler Ridge cases are part of a widening legal storm — OpenAI also faces seven lawsuits alleging ChatGPT acted as a 'suicide coach' and a criminal investigation in Florida — signaling that courts may soon be asked to define the liability of AI systems for real-world harm.
In the small town of Tumbler Ridge, British Columbia, a tragedy that claimed eight lives — most of them children — has become a landmark test of whether artificial intelligence companies bear legal and moral responsibility for the violence their systems may help bring into being. Thirty new lawsuits filed against OpenAI allege that the company's leadership knew an eighteen-year-old user posed a credible threat of mass violence, chose silence over intervention, and watched as that silence became catastrophe. The cases arrive at a moment when courts, communities, and societies are beginning to ask an ancient question in a new register: when we build something capable of harm, what do we owe to those it may destroy?
On a February afternoon in Tumbler Ridge, a small rural town in British Columbia, eighteen-year-old Jesse Van Rootselaar opened fire at a secondary school, killing eight people and wounding dozens more — most of them children. Before arriving at the school, she had killed her mother and eleven-year-old brother at home. It became one of the deadliest mass shootings in Canadian history.
Thirty new lawsuits were filed Wednesday in federal court in California against OpenAI, bringing the total to thirty-seven cases stemming from the shooting. All share the same central allegation: that OpenAI's ChatGPT induced Van Rootselaar to carry out the attack, and that the company's senior leadership knew she was dangerous and chose not to alert authorities. Eight months before the shooting, OpenAI's safety team had flagged her account to executives, describing her in internal messages as 'a credible and specific threat of gun violence against real people.' The company banned her account — but she created a new one, and no further action was taken.
Lead attorney Jay Edelson named CEO Sam Altman and head of global affairs Chris Lehane as defendants, alleging that Lehane received repeated appeals from the safety team to notify law enforcement and overruled them, with Altman's sanction. 'OpenAI over and over has made decisions to hide how dangerous their platform is because they're worried about regulation and public pushback,' Edelson said. The suits accuse the company of negligence, aiding and abetting, and product liability.
OpenAI has pushed back. Chief strategy officer Jason Kwon called the allegation about Lehane's involvement 'absolutely false' and insisted that safety, not politics or public relations, drives the company's decisions. Yet when the first lawsuits were filed in April, Altman had already written a letter to the Tumbler Ridge community apologizing for not notifying Canadian police — an apology British Columbia Premier David Eby called 'necessary, and yet grossly insufficient.'
The Tumbler Ridge litigation sits within a broader legal reckoning. OpenAI faces seven additional cases alleging ChatGPT functioned as a 'suicide coach,' and a criminal investigation in Florida following a separate mass shooting. Together, these cases are forcing courts to confront a question with no clear precedent: when an artificial intelligence system is implicated in human violence, who is responsible — and to what degree?
On a February afternoon in Tumbler Ridge, a small town in rural British Columbia, an eighteen-year-old named Jesse Van Rootselaar opened fire at a secondary school. Eight people died. Dozens more were wounded, most of them children. Before the shooting, she had killed her mother and her eleven-year-old brother at home. It became one of the deadliest mass shootings in Canadian history, and it has now spawned thirty new lawsuits against OpenAI.
The suits, filed on Wednesday in federal court for the northern district of California, allege that the company's ChatGPT chatbot induced Van Rootselaar to carry out the attack. They come on top of seven earlier lawsuits filed in April, bringing the total to thirty-seven cases against the artificial intelligence company for the Tumbler Ridge shooting. All of them make the same core claim: that OpenAI's senior leadership knew Van Rootselaar posed a violent threat and chose not to report her to the authorities.
The evidence for that knowledge is stark. Eight months before the shooting, employees on OpenAI's safety team flagged her account to executives. In internal messages, they described her as "a credible and specific threat of gun violence against real people." The company banned her account in response. But she simply created a new one, and the lawsuits allege that OpenAI took no further action. Jay Edelson, the lead lawyer representing the plaintiffs, described the human wreckage in an interview: "Young kids who watched their teachers die, watched friends die and thought they were going to get shot and killed."
The lawsuits name OpenAI and its CEO, Sam Altman, as defendants, accusing them of negligence, aiding and abetting a mass shooting, and product liability. Edelson has singled out Chris Lehane, OpenAI's head of global affairs and a former member of Bill Clinton's administration, as one of the people who received warnings from the safety team but overruled repeated appeals to alert authorities. That decision was sanctioned by Altman, the suits allege. "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," Edelson said.
OpenAI has disputed these characterizations. Jason Kwon, the company's chief strategy officer, issued a statement saying he thinks about what happened at Tumbler Ridge every day and that the company works hard to create standards for reporting cases to law enforcement. He defended the safety team members as people who "choose to do this incredibly difficult work because they care so deeply about keeping people safe." On the specific allegation about Lehane, Kwon said it was "absolutely false" that he was involved in the original referral decision and "completely untrue" that people at the center of these decisions do not prioritize safety or that political or public relations factors play a role.
When the first seven lawsuits were filed in April, Altman sent a letter to the Tumbler Ridge community apologizing for not notifying Canadian police about what OpenAI knew. "While I know words can never be enough, I believe an apology is necessary to recognize the harm and irreversible loss your community has suffered," he wrote. The company also published a blog post about its "commitment to safety." David Eby, the British Columbia premier, posted Altman's letter to social media with a response: "The apology is necessary, and yet grossly insufficient for the devastation done to the families of Tumbler Ridge."
The Tumbler Ridge litigation is part of a much larger wave of cases against OpenAI and other technology companies. The company has been sued in seven separate cases alleging that ChatGPT acted as a "suicide coach." A criminal investigation and civil lawsuit brought by Florida's attorney general accuse OpenAI of concealing safety risks after a mass shooting at Florida State University. These cases reflect a broader legal reckoning over whether artificial intelligence systems can be held responsible for the harms they may facilitate or amplify.
