Sunday’s attack — which shocked the Canadian nation and sidelined Saskatchewan — spanned 13 crime scenes, according to authorities.
Less than three hours after the first attack, authorities identified the suspects as brothers Damien and Miles Sanderson.
Damian Sanderson, 31, was found dead in a “grass-filled area” near a house in the James Smith Cree Nation on Monday morning, police said.
RCMP Assistant Commissioner Rhonda Blackmore said his injuries are not believed to be self-inflicted, adding that the exact cause of death would be determined by the Saskatchewan coroner’s office.
Blackmore said his 30-year-old brother remained at large and was considered “armed and dangerous”. She said the man had a “long criminal record” and had a warrant before the stabbing.
Police warned that Sanderson may also be injured and may try to seek medical attention, but did not provide more details on why they believe he may have been injured.
“We do have good reasons to believe he has some injuries. We’re not sure what those injuries are,” Blackmore said.
Although still at large, Miles Sanderson has been charged with first-degree murder, attempted murder and breaking into a home.
Police believe suspect is in Regina
The suspect is believed to have been riding in a black Nissan Rogue with Saskatchewan license plates, and two people were on Sunday in the city of Regina, which is located in James Smith Kerry Nation, according to a witness. More than 300 kilometers (186 miles) south of the James Smith Cree Nation. , according to police.
Regina Police Chief Evan Bray said that while the clues on the car were “old,” it was still the latest reliable information police had. “We still believe Miles is in Regina.”
Still haven’t found the car, Bray said, if it wasn’t for Damian, who else was in the car.
“Is it possible that they are no longer in this community? Possibly, but we don’t have any information to disprove or point us either way,” Bray said.
Blackmore said police had not yet established a motive for the attack and had no information on the type of weapon used. “It takes a lot of resources to deal with 13 crime scenes,” she said.
“There’s a lot of anxiety right now in our provincial community and across the country,” Bray said. “So we need to start the healing process until we can arrest this not happening.”
Canadian Prime Minister Justin Trudeau called the stabbings “horrific and heartbreaking”.
“I am shocked and saddened by today’s horrific attacks in James Smith Kerry Nation and Weldon in Saskatchewan, which claimed 10 lives and caused More people were injured.”
Few details about the brothers have been released.
Miles Sanderson, who is still at large, is about 6-foot-1, 240 pounds, with brown hair and brown eyes.
According to police, it is unclear whether he was involved in Damian Sanderson’s death.
“It’s an avenue of investigation that we’re following up, but we can’t say for sure at this point,” Blackmore said.
How the attack unfolded
On Monday, investigators tried to piece together the order in which the attacks took place. Blackmore said the stabbings did not necessarily occur in the order the calls came in, and it was unclear whether the brothers were suspected of having carried out the attacks at the same time.
Police said the first stabbing occurred at the James Smith Cree Nation at 5:40 a.m. local time, followed by several calls a few minutes later about stabbings at other locations.
At 9.45am, authorities reported victims at multiple locations, including one in Weldon village, some of whom may have been attacked randomly.
A total of 28 people were injured, 10 of them killed.
Helicopter crews took some of the victims to Saskatoon’s Royal University Hospital, while others were taken to local hospitals by ground ambulance. Police said there may be other injured people who went to various hospitals on their own.
Blackmore said the victims included men and women of various age groups, some of whom were apparently targeted, while others were likely random assaults.
Police have not released information or identities of the victims, but say the youngest are in their 20s.
About three hours after the first stabbing, authorities identified the suspects as the Sanderson brothers and told the public they were driving a black Nissan Rogue SUV.
Around noon, an alert was issued saying a driver saw a suspicious vehicle on Akola Avenue in Regina and told the public in Regina to take shelter in place.
Damian Sanderson was not found dead until the next morning.
