Thirty new lawsuits tied to the Tumbler Ridge shooting accuse OpenAI of failing to act on warning signs before the deadly 2026 attack.
Tumbler Ridge Shooting: 30 New Lawsuits Hit OpenAI
The legal fallout from the Tumbler Ridge school shooting is growing.
Thirty new lawsuits have been filed against OpenAI in the United States by students, teachers and school staff who survived the deadly attack in northern British Columbia.
The cases add to seven earlier lawsuits. Together, they bring the number of claims linked to the shooting to 37. The new cases also raise a serious question: did OpenAI have enough warning to act before the tragedy?
Lawsuits target OpenAI and Sam Altman
The latest complaints were filed in a California federal court.
The plaintiffs accuse OpenAI and CEO Sam Altman of failing to respond properly to warning signs linked to the shooter’s use of ChatGPT.
They also allege that the company helped create conditions that allowed the attack to happen.
Importantly, these are allegations. They have not been proven in court.
The new lawsuits go further than the earlier cases. They accuse OpenAI of aiding and abetting the shooting, along with claims involving negligence and product liability.
What happened in Tumbler Ridge?
The attack took place on Feb. 10, 2026, in Tumbler Ridge, B.C.
Eight people died in the shooting. The victims included five children and an educator at Tumbler Ridge Secondary School.
The attacker, 18-year-old Jesse Van Rootselaar, also killed her mother and half-brother before the school attack. She later died from a self-inflicted gunshot wound, according to police.
The tragedy shocked the small northern B.C. community and drew national attention.
Now, months later, the legal battle is putting the role of artificial intelligence under a fresh spotlight.
Questions over ChatGPT warnings
OpenAI has said an account linked to Van Rootselaar was identified months before the shooting.
The company said the account was banned after activity broke its rules. However, OpenAI decided not to refer the user to police because it did not believe the activity showed an imminent and credible threat of serious physical harm.
The plaintiffs challenge that decision.
According to the lawsuits, OpenAI employees had raised concerns about conversations involving violence and had urged the company to contact Canadian law enforcement. Instead, the original account was closed. The lawsuits claim the user later returned through another account.
That decision now sits at the centre of the legal fight.
Survivors join the legal action
The latest plaintiffs include students, teachers and a school principal.
Some were inside the school during the attack but were not physically injured.
Their lawsuits describe the lasting impact of the shooting. They also argue that OpenAI should have taken stronger steps after its systems detected troubling activity.
For the survivors, the issue is not only what happened on Feb. 10. It is also what the company knew before that day and how it responded.
OpenAI rejects key claims
OpenAI has pushed back against the allegations.
The company’s chief strategy officer, Jason Kwon, has disputed claims that its safety teams ignored the risk or that company leaders put other interests ahead of public safety.
OpenAI has also said its approach to serious threats has changed since the Tumbler Ridge tragedy.
The company has strengthened its safety measures and said it would now report similar activity when it meets the relevant threshold. CEO Sam Altman also apologized to the Tumbler Ridge community.
Still, the lawsuits could force the company to answer difficult questions about how its safety systems worked before the shooting.
B.C. is also pursuing action
The legal pressure is not limited to victims and survivors.
In July, the B.C. government said it had retained legal counsel to pursue action against OpenAI.
Attorney General Niki Sharma said the province wanted to hold the company and its decision-makers accountable over the alleged failure to alert law enforcement before the attack.
As a result, OpenAI now faces legal scrutiny from several directions.
A wider test for AI safety
The Tumbler Ridge cases could become an important test for the growing AI industry.
At their heart is a difficult question: when an AI company detects troubling conversations, when should it involve police?
There is no simple answer.
Companies must protect users’ privacy. At the same time, they must respond when technology may be linked to a real-world threat.
The lawsuits will now test where that line should be drawn.
For Tumbler Ridge survivors and families, however, the issue is deeply personal.
They want answers about what happened before the shooting, why warnings did not lead to police contact and whether stronger action could have changed the outcome.
Those questions will now move from public debate into the courtroom.
