A four-day manhunt has come to an end in Canada, with a second suspect dying after police arrested him over multiple stabbings in the province of Saskatchewan.
It comes after the first suspect — a brother of the second suspect — was found dead earlier this week soon after one of the deadliest attacks in Canada's history.
Here's what we know about the suspects and how the search for them unfolded.
After stabbings at 13 locations, a manhunt began
Police said they were called to the sites of several stabbings in an Indigenous community and in a nearby town early on Sunday morning.
Victims were found at 13 different locations in Saskatchewan, on the sparsely populated First Nations reserve belonging to the James Smith Cree Nation, and in the town of Weldon about 30 kilometres away.
Authorities said 10 people were killed and another 18 injured in the attacks.
They named two suspects — brothers Damien Sanderson and Myles Sanderson, both in their early thirties.
Authorities issued alerts for Canada's three vast prairie provinces as part of their manhunt — Saskatchewan and the adjacent provinces of Manitoba and Alberta — and contacted US border officials.
The Royal Canadian Mounted Police (RCMP) told residents not to approach either of the suspects, and charged both brothers with first-degree murder.
The first suspect was found dead
Police said the elder brother, Damien, was found dead on Monday on the James Smith Cree Nation, not far from the sites of the stabbings.
He was found with injuries which police didn't believe were self-inflicted, and police said younger brother, Myles was still at large and likely injured.
Officers believed Myles Sanderson was somewhere in Regina, the capital city of Saskatchewan, about 335 kilometres south of where the stabbings took place.
Police encountered a false alarm
On Tuesday, police surrounded a house on the James Smith Cree Nation reserve, with their guns drawn.
Emergency alerts had been sent to nearby phones, telling people to stay inside.
Witnesses said they saw people running away as police closed nearby roads.
Police later said it was a false alarm, and that Myles Sanderson, the only remaining suspect, wasn't believed to be on the reserve.
Then the second brother was found
On Wednesday, the fourth day of the search, police arrested Myles Sanderson — not in Regina but near the town of Rosthern, just over 100 kilometres south-west of the James Smith Cree Nation reserve.
Police said the arrest took place after officers responded to a report of a stolen car being driven by a man armed with a knife.
Officers forced Sanderson's vehicle off the road and into a ditch before he was detained and a knife was found in the vehicle, authorities said.
Vision from the scene showed a white SUV to the side of a road, surrounded by police cars and with its airbags deployed.
Assistant Commissioner Rhonda Blackmore said Sanderson went into "medical distress" after he was arrested and CPR was attempted on him before an ambulance arrived.
She said emergency medical personnel took him to a hospital, where he was pronounced dead.
"All life saving measures that we are capable of were taken at that time," she said.
Ms Blackmore gave no details on the cause of death, which she said would be determined by an autopsy.
An official who spoke earlier on condition on anonymity had said Sanderson died of self-inflicted injuries, but didn't give any details.
Some family members of the victims had travelled to the scene and thanked police, including Brian Burns, whose wife and son were killed.
"Now we can start to heal. The healing begins today, now," he said.
Families of a number of the victims also held an emotional press conference, mourning their losses.
Police shared more information about the brothers
Police said they were investigating whether Myles Sanderson had killed his brother and subsequently gone on the run, but admitted it would be hard to confirm what started their rampage, given both men were dead.
The incident has also raised concerns about why Myles — a former inmate with a long criminal history, including 59 convictions — had been released from prison by a parole board in February.
He had been serving a sentence of over four years on charges which included assault and robbery.
He had also been wanted by police since May, reportedly for violating the terms of his release, though the details were not immediately clear.
Myles had attacked and stabbed one of the victims of the weekend's rampage seven years ago, according to court records.
Canadian Public Safety Minister Marco Mendicino said there will be an investigation into the parole board's assessment of Myles.
"I want to know the reasons behind the decision" to release him, Mr Mendicino said.
"I'm extremely concerned with what occurred here. A community has been left reeling."
Very little has been reported about Damien Sanderson's background.
Investigators said some of the stabbing victims were targeted and others appeared to have been chosen at random.
Police haven't provided a motive, but the chief of the Federation of Sovereign Indigenous Nations suggested the stabbings may have been drug-related.
