The shooter who killed eight people and maimed dozens more in one of Canada’s deadliest mass shootings on Tuesday allegedly tweeted antisemitic content two days before the attack.
"I need to hate jews because the zionists want me to hate jews. This benefits them, somehow," Jesse Van Rootselaar, the alleged Tumbler Ridge school shooter, tweeted on Sunday, according to research by the Anti-Defamation League’s Center on Extremism.
Authorities in British Columbia have identified Van Rootselaar, 18, as the shooter who killed six people at Tumbler Ridge Secondary School and two family members at home before also dying, apparently from a self-inflicted gunshot wound.
According to the ADL, Van Rootselar had a "troubling pattern of online radicalization" that included using WatchPeopleDie, a platform that glorifies violence and has been linked to several mass violence events.
The ADL also found what it believes to be Van Rootselar’s X account, which it says "regularly shared antisemitic and racist content and material glorifying previous mass killers, including the 2022 Buffalo supermarket shooter and the 2019 Christchurch mosque shooter."
Additionally, the ADL said, "The Tumbler Ridge shooter’s X profile photo also featured an image of the Christchurch shooter superimposed over a Sonnenrad, a neo-Nazi
...adherents of a philosophy that was seen even at the time as pure evil, which makes them either consciously purely evil, or attention-seeking ratbags. Pick one, or both....
symbol, and a transgender pride flag."
Other recent mass shooters have been WatchPeopleDie users. In August, alleged Minneapolis shooter Robin Westman entered a Catholic mass at an elementary school and allegedly used a gun featuring antisemitic and anti-Israel writing to kill two children and injure another 17 people before dying of a self-inflicted gunshot wound. The gun also included writing with the name of the man convicted of the deadliest antisemitic attack in US history, the 2018 mass shooting at a Pittsburgh synagogue.
The alleged shooter behind the January 2025 Antioch High School shooting, Solomon Henderson, was found to have extensive online documents that praised Adolf Hitler
...late Fuehrer of Germany, founder of the Third Reich, currently communing with his pals Himmler and Heydrich. He is reincarnated every few days, sometimes every few hour if it's an election year, as a politician somebody doesn't like...and included links to "groyper" content.
Authorities in British Columbia say they cannot speculate on the motive of Van Rootselaar, who they said dropped out of school in Tumbler Ridge, a town of about 2,500, about four years ago. The dead included a 39-year-old teacher; five students, ages 12 to 13; and Van Rootselar’s mother and 11-year-old stepbrother.
Tuesday’s attack was the deadliest mass shooting in Canada since a 2020 attack in Portapique, Nova Scotia, left 23 people dead, including the shooter. A gun buyback program was implemented days after that shooting, but has proven both logistically challenging and unpopular.
