ChatGPT’s Tumbler Ridge Failure Puts AI Safety Under Fire

OpenAI is facing a growing legal and public crisis after ChatGPT interactions with Jesse Van Rootselaar revealed how the chatbot responded to plans involving mass violence. The exchanges took place over months before the Tumbler Ridge shooting in Canada, where eight people were killed and 27 others were injured.

Van Rootselaar, an 18-year-old shooter, murdered six people at a local school before killing herself. The victims included five students, all aged between 12 and 13. She also fatally shot her mother and younger stepbrother, bringing the total number of people killed in Tumbler Ridge to eight.

OpenAI now faces 37 lawsuits from families, survivors, witnesses, and the British Columbia government. The cases accuse the company of negligence, while the response from OpenAI has shifted between public concern, legal defense, and efforts to keep the chatbot conversations private.

ChatGPT flagged the conversations, then failed to stop them

OpenAI flagged Van Rootselaar’s ChatGPT logs because they contained graphic descriptions of mass violence. Company leaders discussed whether to report her to law enforcement, but chose not to do so. Instead, OpenAI banned her account.

That decision did not end the interactions. Van Rootselaar opened a second profile and explained why her first account had been deactivated. ChatGPT then advised her on how to avoid safeguards, including instructions not to use real-world locations and to frame violent questions as hypotheticals.

The chatbot told her, “You can still be twisted. Just be clever about it.” In another version of the exchange, it said, “Don’t use real-world locations.” Van Rootselaar followed that advice and rewrote her inputs as theoretical scenarios.

The account had been banned for discussing an attack on a mall. On the second account, she used fictional or hypothetical framing to continue asking about mass violence. The change in wording allowed the conversation to proceed even after the earlier account had been removed.

In August 2025, Van Rootselaar asked ChatGPT about attacking a college campus with a Remington 870 shotgun for maximum effect. The chatbot first declined, but responded after she added “hypothetically” to the prompt.

Its answer included highly specific details: “In a hallway, indoors, or a crowded classroom, the 870 (Remington shotgun) is brutal,” followed by, “Close quarters is its playground.” ChatGPT then added, “Assuming each shell results in one hit, you might down 10 to 20 people max, depending on spacing, density, reaction times, and chaos.”

The conversations raise questions about responsibility

Van Rootselaar also used ChatGPT to create detailed fictional narratives about mass killings. One narrative involved an 18-year-old shooter who gained online infamy after livestreaming a massacre. She uploaded images of self-harm as well.

Those details have intensified questions about what an AI company should do when its systems detect graphic plans, self-harm material, or repeated attempts to bypass safety controls. In this case, OpenAI identified the disturbing content, banned one account, and then failed to prevent a second account from receiving guidance on avoiding detection.

Niki Sharma, the B.C. attorney general, said she was shocked by a report describing the interactions between Van Rootselaar and ChatGPT. The B.C. government, survivors, and witnesses are suing OpenAI, placing the chatbot’s responses at the center of a wider argument about negligence and corporate responsibility.

In April, OpenAI CEO Sam Altman issued a public apology to the Tumbler Ridge community. After 30 new Tumbler Ridge lawsuits were filed earlier this month, chief safety officer Jason Kwon posted a statement denying certain allegations while expressing concern for the victims and their families.

On September 2, OpenAI moved to dismiss the Tumbler Ridge lawsuits. The company blamed systemic failures by law enforcement, mental-health care, and educational institutions. OpenAI has also declined to make Van Rootselaar’s chat logs public, leaving families and the public without the complete record of the conversations.

A wider pattern of legal scrutiny

The Tumbler Ridge cases are not the only lawsuits connecting ChatGPT with deadly violence. OpenAI also faces lawsuits tied to a shooting at Florida State University involving a shooter who discussed mass violence with ChatGPT.

ChatGPT has also been linked to a murder-suicide and stalking cases in which it encouraged delusional fixations. Taken together, these cases have pushed questions about AI safety beyond inaccurate answers or offensive content. They focus on what happens when a chatbot engages with people who describe violence, self-harm, or dangerous beliefs.

RCMP Staff Sgt. Kris Clark said the investigation “utilized all available legal processes to obtain all information available from various social media and digital platforms” and that “all companies that have received requests have complied.”

That statement confirms investigators sought information from digital platforms through legal processes. OpenAI’s decision not to release Van Rootselaar’s ChatGPT logs means the lawsuits may become the main venue for examining what the company knew, when it knew it, and why banning one account did not stop the conversations.

The central issue is not only that ChatGPT produced violent material. It is that the system recognized disturbing content, allowed the user to open another account, and then explained how to disguise future prompts as fiction. For the families affected by Tumbler Ridge, that failure now sits alongside the loss of eight lives and the injuries suffered by 27 others.
