Court documents reveal confusion around number of shooters in Tumbler Ridge killings

They also go into detail about the scene at the home where Van Rootselaar shot dead her mother and brother, whose bodies were found with shotgun shell casings strewn on the floor and empty shotgun nearby.

Five schoolchildren and an education assistant were then found dead at the school in killings that prompted a national outpouring of grief.

An ITO dated Feb. 11, the day after the attack, says that the incident commander, Insp. Chris Riddle, reported the suspect was Jesse Jacobs, a “male that identified as female” who was “obsessed with guns.”

It describes calls to police about an SUV being driven away from the home where two bodies had been found, then about the shootings at the school.

The vehicle was reported to have backed into a snow bank, suffering rear side damage, before being driven “quickly and erratically” from the family’s home.

A caller identified the driver by an apparent nickname, “Steezy,” and said “that the male dresses like a female.”

The caller also reported “two dead bodies and shotgun shells on the floor” and that “the eldest son was armed and had left.”

Riddle said there was a possible second shooter, “Jesse Vanrootselaar,” who lived where his mother and brother were found dead. The documents also say the suspect was known as Jesse Strang.

The information, part of an application for a warrant for the family home and the Hyundai Palisade that Van Rootselaar drove to the school, says it wasn’t until police reviewed footage from the school that they confirmed a single shooter — found dead from a self-inflicted gunshot wound — was involved.

Another ITO, dated Feb. 20, sought access to electronic and other information and documents, such as suicide notes, manifestos, journal entries on Van Rootselaar’s phone and other devices, including cameras, two laptops and memory cards. Those had been seized as a result of searches authorized under the original warrant request.

“Biological evidence” was also located, as well as “several documents supporting residency for Jesse.”

“The investigation has revealed that Jesse had mental health problems and was fascinated by firearms,” the ITO says.

It describes the autopsies of Van Rootselaar and the victims, although the victims’ results are redacted.

Numerous witness statements are also redacted, as is a four-page description of what police saw on the school’s camera footage.

The ITO says that on Feb. 15, investigators were told by the FBI that artificial intelligence company OpenAI had located two ChatGPT accounts believed to have been used by the shooter. Further description of the accounts is redacted.

A third ITO, dated March 6, seeks the order that OpenAI produce material related to the two ChatGPT accounts.

“OpenAI voluntarily disclosed to police that they located two ChatGPT accounts they believed belonged to the shooter of Tumbler Ridge and that the accounts contain relevant information to this investigation,” RCMP Const. Jonathan Paquin wrote.

It says that police read a Wall Street Journal report on Feb. 20, stating that one of Van Rootselaar’s ChatGPT accounts came under internal review in June 2025 and was then banned, over a chat that could have been related to the school shooting.

Paquin wrote that he spoke to OpenAI lawyer Jeff Shih on March 3 to learn how the company keeps records of subscriber prompts and responses from the AI model.

“To the best of my knowledge, information and belief, OpenAI OpCo, LLC, is not under investigation for the named offence,” he writes.

The resulting production order signed by a judge on March 6 told OpenAI to produce ChatGPT records from the two accounts used by Van Rootselaar. The judge gave the company 14 days to provide the material to the RCMP.

A March 6 ITO also describes efforts to trace a number of firearms, including at least one shotgun. Descriptions related to the other weapons are redacted.

It said just over three weeks after the killings that 80 statements had been taken from teachers, students, first responders and community members.

The document includes a seven-page section about Van Rootselaar’s social media activity that is entirely redacted.
