Canadian police named him as Damien Sanderson, saying the 31-year-old was found dead on the James Smith Cree Nation, one of the locations of the stabbings. Meanwhile, searches continue for his brother and the other suspect Miles, with police saying they believe he is in Regina, Saskatchewan’s capital and about 210 miles south of where the stabbings happened. Speaking on Monday afternoon local time, officers said Miles was believed to be injured and could seek medical attention. “Even if he’s injured, it doesn’t mean he’s not still dangerous. “Miles has a lengthy criminal record involving both person and property crimes,” they added. “We consider him armed and dangerous. Do not approach him. If you know where he is, call 911.” Miles Sanderson has been “unlawfully at large” since May, when a local crime appeal was issued in an attempt to trace him. He was serving a nearly five-year sentence for offenses including assault and robbery and was given probation but then disappeared, according to CBC News. Police in Canada’s three vast prairie provinces of Saskatchewan, Manitoba and Alberta have been alerted, along with US border officials. Image: RCMP manhunt after stabbings in Saskatchewan, Canada The stabbings, which left 18 injured, are one of the deadliest mass killings in Canadian history. Authorities said some of the victims were targeted and others appear to have been chosen at random in the James Smith Cree Nation and the town of Weldon in Saskatchewan province. No motive has been reported, but Bobby Cameron, head of the Federation of Sovereign Indigenous Nations, told The Associated Press that the stabbings may be drug-related. “This is the disaster we face when harmful illegal drugs invade our communities and we demand that all authorities take direction from their chiefs and councils and members to create safer and healthier communities for our people.” Read more: Trudeau urges public to ‘beware’ of two men suspected of killing 10 people In a televised statement, Canadian Prime Minister Justin Trudeau described the stabbings as “shocking and heartbreaking.” He added: “This kind of violence, or any kind of violence, has no place in our country. “Keeping you and your loved ones safe is a priority, so please be careful.”
