Jesse Van Rootselaar (August 4, 2007 – February 10, 2026),[41][42] also known as Jesse Strang,[43][44][45] was identified as the shooter by RCMP deputy commissioner Dwayne McDonald,[18] after initially being described by the RCMP as "a female in a dress with brown hair".[46][47] McDonald stated that Van Rootselaar was a trans woman.[18][48] Van Rootselaar had dropped out of school about four years prior;[49] McDonald disclosed that there was no information that suggested she was bullied at school.[50][51] Van Rootselaar and her siblings had been the subject of custody disputes between their parents, and had moved between Newfoundland and Labrador and Western Canada multiple times between 2010 and 2015.[52] Van Rootselaar's father said that Jesse never used the Van Rootselaar name, and that he had not been part of Jesse's life "due to decisions by Jesse's mother."[53]
Van Rootselaar's YouTube profile picture featured a female anime character and rifle set against a pink-and-white-striped background.[54] Her TikTok account, which used the same profile image as the YouTube account, featured multiple reposted videos of a transgender mass shooter who killed six people at a Christian school in Nashville in 2023.[54]
Van Rootselaar additionally described trying to "burn [her] house down after using psychedelic mushrooms, and regularly took DMT – another powerful hallucinogenic drug."[55] The mother of one of the victims, who was also friends with the shooter's family, confirmed that Jesse had "tried to light a mattress on fire 'and burn the house down.'"
Obviously, the information is subject to change (as Wiki info often can be)
...but a lot to unpack here. The fact that Jesse (if Wiki is true) was repeatedly posting TikTok content about the Tennessee mass shooter (who was Trans, and left behind a manifesto explaining their reasons for the shooting that were ideologically motivated), should have been a red flag.
Sounds like there was a dispute about something between the parents.
If the mother was that hands-off that they were allowing their child to drop out of school at age 14, and evidently let them play with guns despite having a pretty apparent mental health problem and an affinity for psychedelic drugs that detached them from reality
It's the part of this that nobody wants to talk about out of fear of getting cancelled, but the reality is that gender dysphoria seems to go hand-in-hand with some other pretty serious mental illnesses.
The rates of schizophrenia and other severe personality disorders are nearly 50 times higher in people aged 10-17 who identify as non-conforming vs their cisgender counterparts.
By trying to eliminate the pathology aspect in efforts to "normalize" to spare peoples' feelings, it's caused society (and the medical profession) to overlook certain things and perhaps prescribe the wrong approach.
Given that huge contrast in personality disorder rates, prudence would dictate that if a young person presents with the "I feel like I should have been born as the other sex, and its got me all messed up in the head", a responsible practitioner would first try to assess if it's a legitimate case of gender dysphoria as a stand-alone issue, or is it one of the other aforementioned disorders causing gender dysphoria.
There used to be a little higher of a bar to clear, the fact that so many young people are identifying this way now vs. 20 years ago (and how high the rates of personality disorders are among them) could be an indicator that situations what would've been appropriately diagnosed as a personality disorder (and treated with meds) are now just being immediately chalked up as "They're trans, that's all there is to it, everyone just needs to affirm that starting ASAP, no more questions allowed" is leaving underlying conditions undiagnosed and untreated.
There are cases in the medial literature that used to be studied and reported on before it was considered "off-limits" to ask about
Here's one from the NIH:
The authors present clear pattern of gender identity variations coinciding solely with psychotic episodes during schizoaffective disorder, bipolar type. The authors postulate that gender dysphoria can co-occur with other psychiatric disorders and may correspond with acute psychosis. The distinction is critical to make to ensure accurate diagnoses regarding whether gender dysphoria is a symptom of psychotic illness, or if there is a longer-standing concern as to the patient’s gender identity and assignment.
In this case report, the patient will be referred to without using pronouns given fluctuations in pronouns over time. A Hispanic person, assigned male at birth (AMAB), identified as female upon admission. The patient denied any significant or contributing past medical history. The patient had a past psychiatric history of schizoaffective disorder, bipolar type, and presented involuntarily to the psychiatric inpatient unit for bizarre behavior and hallucinations for the past three months. Per the patient’s mother’s report, the patient had been refusing to eat, was easily agitated, and was exhibiting signs of mania.
