One of the suspects in the stabbing deaths of 10 people in the Canadian province of Saskatchewan has been found dead, and his injuries are not self inflicted, police said Monday as they continued the search for a second suspect.

Regina Police Chief Evan Bray said Damien Sanderson, 31, was found dead near the stabbing sites and they believe his brother, Myles Sanderson, 30, is injured, on the run and likely in the provincial capital of Regina. It was the first time police have identified the two as brothers.

“His body was located outdoors in a heavily grassed area in proximity to a house that was being examined. We can confirm he has visible injuries. These injuries are not believed to be self-inflicted at this point," said RCMP Commanding Officer Assistant Commissioner Rhonda Blackmore, adding they were not sure of the exact cause of death yet.

Asked if Myles Sanderson was responsible for his brother’s death, Blackmore said police are investigating that possibility, but "we can’t say that definitively at this point in time.″

The discovery of the body came on the second day of a massive manhunt for the pair, who are suspected of carrying out a series of stabbings in an Indigenous community and a nearby town, which also left 18 people injured. It was one of the deadliest attacks in the nation’s history.

Authorities have said some of the victims were targeted and others appeared to have been chosen at random on the James Smith Cree Nation and in the town of Weldon in Saskatchewan. They have given no motive for the crimes— but senior Indigenous leaders suggested drugs were somehow involved.

James Smith Cree Nation resident Darryl Burns and his brother, Ivor Wayne Burns, said their sister, Gloria Lydia Burns, was a first responder who was killed while trying to respond to a call. Burns said his 62-year-old sister was on a crisis response team.

“She went on a call to a house and she got caught up in the violence,” he said. “She was there to help. She was a hero.”

He blamed drugs and pointed to the colonization of Indigenous people for the rampant drug and alcohol use on reserves.

“We had a murder suicide here three years ago. My granddaughter and her boyfriend. Last year we had a double homicide. Now this year we have 10 more that have passed away and all because of drugs and alcohol,” Darryl Burns said.

Ivor Wayne Burns also blamed drugs for his sister’s death and said the suspect brothers should not be hated.

“We have to forgive them boys,” he said. “When you are doing hard drugs, when you are doing coke, and when you are doing heroin and crystal meth and those things, you are incapable of feeling. You stab somebody and you think it’s funny. You stab them again and you laugh.”

While authorities believe Myles is in Regina, about 335 kilometers (210 miles) south of where the stabbings happened, they have issued alerts in Canada's three vast prairie provinces — which also include Manitoba and Alberta — and contacted U.S. border officials.

With one suspect still at large, fear still gripped communities in the rural, working class area of Saskatchewan surrounded by farmland that were terrorized by the crimes. One witness who said he lost family members described seeing people with bloody wounds scattered throughout the Indigenous reserve.

“No one in this town is ever going to sleep again. They’re going to be terrified to open their door,” said Ruby Works, who also lost someone close to her and is a resident of Weldon, which has a population of about 200 and is home to many retirees.

As the Labor Day holiday weekend drew to a close Monday, police urged Saskatchewan residents who were returning from trips away to look for suspicious activity around their homes before entering.

Arrest warrants have been issued for the pair of suspects and both men faced at least one count each of murder and attempted murder. More charges were expected.

Police have given few details about the men. Last May, Saskatchewan Crime Stoppers issued a wanted list that included Myles Sanderson, writing that he was “unlawfully at large.”

While the manhunt continued, police also issued a provincewide alert for suspects in a shooting on the Witchekan Lake First Nation. Officials said the shooting was not believed to be connected to the stabbings, but such alerts are unusual and the fact that a second occurred while authorities were already scouring the Saskatchewan for the stabbing suspects was notable.

The stabbing attack was among the deadliest mass killings in Canada, where such crimes are less common than in the United States. The deadliest gun rampage in Canadian history happened in 2020, when a man disguised as a police officer shot people in their homes and set fires across the province of Nova Scotia, killing 22 people. In 2019, a man used a van to kill 10 pedestrians in Toronto.

Deadly mass stabbings are rarer than mass shootings, but have happened around the world. In 2014, 29 people were slashed and stabbed to death at a train station in China’s southwestern city of Kunming. In 2016, a mass stabbing at a facility for the mentally disabled in Sagamihara, Japan, left 19 people dead. A year later, three men killed eight people in a vehicle and stabbing attack at London Bridge.

Police in Saskatchewan got their first call about a stabbing at 5:40 a.m. on Sunday, and within minutes heard about several more. In all, dead or wounded people were found at 13 different locations on the sparsely populated reserve and in the town, Blackmore said. James Smith Cree Nation is about 30 kilometers (20 miles) from Weldon.

On Monday, Blackmore said police were still determining the motive, but on Sunday the chief of the Federation of Sovereign Indigenous Nations echoes suggestions the stabbings could be drug-related.

“This is the destruction we face when harmful illegal drugs invade our communities, and we demand all authorities to take direction from the chiefs and councils and their membership to create safer and healthier communities for our people,” said Chief Bobby Cameron.

Blackmore said the criminal record of Myles Sanderson dates back years and includes violence.

The elected leaders of the three communities that make up the James Smith Cree Nation declared a local state of emergency.

Chakastaypasin Chief Calvin Sanderson — who apparently is not related to the suspects — said everyone has been affected by the tragic events.

“They were our relatives, friends," Sanderson said of the victims. “It’s pretty horrific.”

Among the 10 killed was Lana Head, who is the former partner of Michael Brett Burns and the mother of their two daughters.

"It’s sick how jail time, drugs and alcohol can destroy many lives,” Burns told the Aboriginal Peoples Television Network. “I’m hurt for all this loss.”

Burns later posted on Facebook that there were dead and wounded people everywhere on the reserve, making it look like "a war zone.”

“The look in their eyes couldn’t express the pain and suffering for all those who were assaulted,” he posted.

Weldon residents have identified one of the dead as Wes Petterson, a retired widower who made the coffee every morning at the senior center. He loved gardening, picking berries, canning, and making jam and cakes, recalled William Works, 47, and his mother, Sharon Works, 64.

“He would give you the shirt off his back if he could,” William Works said, describing his neighbor as a “gentle old fellow” and “community first.”

Sharon Works was baffled: “I don’t understand why they would target someone like him anyway, because he was just a poor, helpless little man, 100 pounds soaking wet. And he could hardly breathe because he had asthma and emphysema and everybody cared about him because that’s the way he was. He cared about everybody else. And they cared about him.”

Prime Minister Justin Trudeau said the flag above Canada’s parliament building in Ottawa would be flown at half-staff to honor the victims.

“Saskatchewanians and Canadians will do what we always do in times of difficulty and anguish, we will be there for each other," Trudeau said.
