Police confirmed they were called multiple times to the home of Jesse Van Rootselaar, 18, the teen responsible for one of Canada's deadliest school shootings. The attack on Tuesday in Tumbler Ridge killed six people, including a teacher and five children, and injured about 25 others. Two injured remain in critical but stable condition. The suspect was found at the school with a self-inflicted gunshot wound. Van Rootselaar's mother and step-brother were also found dead at their home. Authorities said the family was known to police for mental health concerns over several years. RCMP Deputy Commissioner Dwayne McDonald said officers had attended the residence multiple times, including to seize firearms. "At a later point in time, the lawful owner of those firearms petitioned for those firearms to be returned and they were," McDonald added. The suspect had an expired firearms licence in 2024 and no guns registered in their name. British Columbia Premier David Eby expressed concern about returning firearms to a home under mental health watch. Former RCMP officer Sherry Benson-Podolchuk noted that stricter laws are needed to allow police to seize guns during mental health checks. Canada has tighter gun laws than the US, including bans on assault-style firearms and handgun sales freezes. The victims included 12-year-old Kylie Smith and Abel Mwansa Jr. Family members mourned their loss on social media, describing their bright futures and loving nature. Police clarified that the suspect was born male and began transitioning to female about six years ago. Following false claims linking the shooting to the suspect's gender identity, experts warned against stereotyping entire groups based on one individual. Research shows transgender people face higher risks of being crime victims, not perpetrators. The motive behind the attack is still unknown and the investigation is ongoing. Canadian Prime Minister Mark Carney plans to visit the small town of 2,400 residents on Friday.
