ROSTHERN, Saskatchewan (AP) — The final suspect in a stabbing rampage that killed 10 people in and around a Canadian Indigenous reserve died after his car was run off the road by police Wednesday following a three-day manhunt, officials said.

Myles Sanderson, 32, was caught on a highway near the town of Rosthern in the province of Saskatchewan as officers responded to a report of a stolen vehicle being driven by a man armed with a knife, the Royal Canadian Mounted Police said.

Officers forced Sanderson’s vehicle off the road and into a ditch, Assistant Commissioner Rhonda Blackmore, commander of the RCMP in Saskatchewan, said at a news conference.

She said Sanderson went into medical distress after the was arrested. She said emergency medical personnel took him to a hospital, where he was pronounced dead.

Blackmore gave no details on the cause of death. “I can’t speak to the specific manner of death,” she said.

But an official, who spoke on condition of anonymity, earlier said Sanderson died of self-inflicted injuries, without giving any further details.

Video and photos from the scene showed a white SUV off to the side of the road with police cars all around. Air bags had deployed in the SUV. Some photos and video taken from a distance appeared to show Sanderson being frisked.

His death came two days after the body of his brother, 30-year-old Damien Sanderson, was found in a field near the scene of their rampage, which also wounded 18 people. Police are investigating whether Myles Sanderson killed his brother.

Blackmore said that with both men dead, authorities will find it hard to figure out what set off the rampage.

“Now that Myles is deceased we may never have an understanding of that motivation,” she said.

But she started off her remarks that the news conference by stressing that people in Saskatchewan can rest easier.

“This evening our province breathing a collective sigh of relief,” Blackmore said.

Later, she added: “I hope that this brings them closure. I hope they can rest easy knowing that Myles Sanderson is no longer a threat to them.”

Some family members of the victims arrived at the scene Wednesday, including Brian Burns, whose wife and son were killed.

“Now we can start to heal. The healing begins today, now,” he said.

The stabbing rampage raised questions of why Myles Sanderson — an ex-con with 59 convictions and a long history of shocking violence — was out on the streets in the first place.

He was released by a parole board in February while serving a sentence of over four years on charges that included assault and robbery. But he had been wanted by police since May, apparently for violating the terms of his release, though the details were not immediately clear.

His long and lurid rap sheet also showed that seven years ago, he attacked and stabbed one of the victims killed in the weekend rampage, according to court records.

Canadian Public Safety Minister Marco Mendicino said there will be an investigation into the parole board’s assessment of Sanderson.

“I want to know the reasons behind the decision” to release him, Mendicino said. “I’m extremely concerned with what occurred here. A community has been left reeling.”

Investigators have not given a motive for the bloodshed.

The Saskatchewan Coroner’s Service said nine of those killed were from the James Smith Cree Nation: Thomas Burns, 23; Carol Burns, 46; Gregory Burns, 28; Lydia Gloria Burns, 61; Bonnie Burns, 48; Earl Burns, 66; Lana Head, 49; Christian Head, 54; and Robert Sanderson, 49, One was from Weldon, 78-year-old Wesley Patterson.

Authorities would not say how the victims might be related.

Mark Arcand said his half sister Bonnie and her son Gregory were killed.

“Her son was lying there already deceased. My sister went out and tried to help her son, and she was stabbed two times, and she died right beside him,” he said. “Right outside of her home she was killed by senseless acts. She was protecting her son. She was protecting three little boys. This is why she is a hero.”

Arcand rushed to the reserve the morning of the rampage. After that, he said, “I woke up in the middle of the night just screaming and yelling. What I saw that day I can’t get out of my head.”

As for what set off the violence, Arcand said: “We’re all looking for those same answers. We don’t know what happened. Maybe we’ll never know. That’s the hardest part of this.”

Court documents said Sanderson attacked his in-laws Earl Burns and Joyce Burns in 2015, knifing Earl Burns repeatedly and wounding Joyce Burns. He later pleaded guilty to assault and threatening Earl Burns’ life.

Many of Sanderson’s crimes were committed when he was intoxicated, according to court records. He told parole officials at one point that substance use made him out of his mind. Records showed he repeatedly violated court orders barring him from drinking or using drugs.

Many of Canada’s Indigenous communities are plagued by drugs and alcohol.

“The drug problem and the alcohol problem on these reserves is way out of hand,” said Ivor Wayne Burns, whose sister was killed in the weekend attacks. “We have dead people, and we asked before for something to be done.”

Myles Sanderson’s childhood was marked by violence, neglect and substance abuse, court records show. Sanderson, who is Indigenous and was raised on the Cree reserve, population 1,900, started drinking and smoking marijuana at around 12, and cocaine followed soon after.

In 2017, he barged into his ex-girlfriend’s home, punched a hole in the door of a bathroom while his two children were hiding in a bathtub and threw a cement block at a vehicle parked outside, according to parole documents.

He got into a fight a few days later at a store, threatening to kill an employee and burn down his parents’ home, documents said.

That November he threatened an accomplice into robbing a fast-food restaurant by clubbing him with a gun and stomping on his head. He then stood watch during the holdup.

In 2018, he stabbed two men with a fork while drinking and beat someone unconscious.

When he was released in February, the parole board set conditions on his contact with his partner and children and also said he should not enter into relationships with women without written permission from his parole officer.

In granting Sanderson “statutory release,” parole authorities said: “It is the Board’s opinion that you will not present an undue risk to society.”

Canadian law grants prisoners statutory release after they serve two-thirds of their sentence. But the parole board can impose conditions on that freedom, and inmates who violate them — as Sanderson did more than once — can be ordered back to prison.

Sharna Sugarman, who was organizing a GoFundMe for the victims, questioned the parole board for releasing him and wondered why Sanderson was still on the loose so many months after he was deemed “unlawfully at large.”

“That’s just egregious to me,” said Sugarman, a counselor who counted one of the stabbing victims as a client. “If they claim that they’ve been looking for him, well, you weren’t looking that hard.”
