An hour and a half later, at 3:30 p.m., officers spotted the truck going over 90 mph on a freeway and gave chase, Blackmore said. After forcing it into a ditch, officers surrounded the vehicle and arrested Myles Sanderson.
He was alone and it was unclear where he was heading, Blackmore said. After showing signs of distress, officers administered lifesaving measures and an ambulance took him to hospital.
Officers found a knife and no drugs during an initial search of the truck, she said.
It was still unclear what could have led brothers Myles and Damien Sanderson, 31, to embark on the violent frenzy that unfolded Sunday morning on James Smith’s Cree Nation and the town of Weldon. The James Smith Cree Nation is located approximately 200 miles north of the provincial capital, Regina.
The series of stabbing attacks appear to include both targeted victims and random people, officials said.
Investigators had conducted 120 interviews since the stabbings, but “witnesses and people around him only have a limited amount of information,” Blackmore said, referring to Myles Sanderson.
“His motivation can only be known now and forever by Myles,” she said.
Damien Sanderson was found dead on James Smith’s Cree Nation at 11:30 a.m. Monday with visible injuries that do not appear to have been self-inflicted, police said.
In addition to the 10 murders, Myles and Damien Sanderson are believed to have injured 18 people at 13 crime scenes.
Saskatchewan police received the first of several reports of the stabbing around 5:40 a.m. Sunday, and at 7:12 a.m. authorities had the names of their suspects.
The stabbing spree came just months after a parole board freed Myles Sanderson from a four-year sentence for assault and robbery. Myles Sanderson, who had 59 previous convictions, was released in February and by May he was wanted by authorities for violating the conditions of his release.
Court records say that seven years ago Myles Sanderson attacked and stabbed one of the victims who was killed during the weekend rampage.
Security officials said they would review the parole board’s decision to release Myles Sanderson.
“I want to know the reasons for the decision” to release him, said Canadian Public Security Minister Marco Mendicino. “I am extremely concerned about what happened here. A community was left in shock.
The Saskatchewan murders rocked all of Canada, where violent crime is relatively rare.
Prime Minister Justin Trudeau said he had been in close contact with Saskatchewan Premier Scott Moe and Cree Nation leaders James Smith during the crisis.
“I let them know that our government stands ready to help in any way we can and that we are here to support the people of Saskatchewan during this difficult time,” Trudeau said. said in a statement Monday.
