Families of victims from a shooting in Tumbler Ridge, BC, are suing OpenAI for negligence, alleging the company knew of the suspect's threatening AI chats but did not alert police.
The lawsuit puts a spotlight on OpenAI's internal decision not to contact authorities after the suspect described gun violence scenarios on ChatGPT months before the attack.
This case could set a significant legal precedent regarding the responsibilities of AI companies to monitor for potential threats and prevent real-world harm stemming from their platforms.

An OpenAI lawsuit has been filed by families of seven victims from a deadly mass shooting in Canada, alleging the company was negligent in failing to alert police about the suspect’s threatening activity on its ChatGPT platform.
The legal action, filed on Wednesday, accuses OpenAI of product liability violations and aiding and abetting the February attack in Tumbler Ridge, British Columbia. The community of approximately 2,700 people was devastated by the incident, which left eight dead and more than 25 injured.
Representing the families, attorney Jay Edelson stated this marks the first time a community has collectively moved to hold the AI giant accountable for such an event. Among the victims represented is a 12-year-old girl, Maya Gebala, who survived but remains hospitalized after being shot three times.
Suspect's Chats and OpenAI's Decision
Months before the tragedy, OpenAI leaders internally discussed whether to contact law enforcement about the suspect's interactions with ChatGPT. In June of the preceding year, 18-year-old Jesse Van Rootselaar reportedly used the AI tool over several days to describe scenarios involving gun violence.
The company ultimately decided against alerting authorities. Following the February shooting, police identified Van Rootselaar as the suspect, who was subsequently found deceased at the scene of the attack.
In response to the lawsuit, OpenAI has noted that it banned the suspect’s account months before the attack occurred. The company also stated it has since taken steps to bolster its safety protocols.
Calls for Accountability and Community Impact
A spokesperson for OpenAI called the Tumbler Ridge events a tragedy and said the company has improved how it escalates potential violence threats. The firm added it has enhanced its methods for connecting users exhibiting signs of distress with mental health resources and support services.
The victims' families are demanding that OpenAI release the full chat logs of Van Rootselaar's interactions. Edelson has also publicly invited OpenAI CEO Sam Altman and other executives to visit the grieving town to observe the tragedy's impact firsthand.
The shooting has left deep scars on the small mining community. The school where much of the violence took place has been closed, forcing students to attend classes in temporary trailers. This lawsuit now raises critical questions about the legal and ethical duties of AI companies to monitor for and report potential real-world harm generated on their platforms.
