Police in the Saskatchewan city of Saskatoon had been searching for Myles Sanderson since May, when he stopped meeting his parole officer after serving a sentence for assault, robbery, mischief and uttering threats, CBC News reported.
DRUGS AND ALCOHOL BLAMED
Ivor Wayne Burns of James Smith Cree Nation said three of the victims - his sister Gloria Lydia Burns, a woman and a 14-year-old boy - died at a single location.
However police told a press conference on Monday that the youngest victim was born in 1999.
Gloria Burns, a member of the community's crisis response team, was killed when she attended an emergency call.
"This tragedy that happened here on our land, it's all because of drugs and alcohol," said Burns, adding that the involvement of drugs in the killings was discussed at a community meeting on Monday.
"The drug problem we have here is rampant. It's gone out of control," Burns said.
His comments echoed those on Sunday of Chief Bobby Cameron of the Federation of Sovereign Indigenous Nations, who connected the killings with drugs.
Although police have not identified drugs or alcohol as a factor, Burns said the men responsible for the killings are band members and were high at the time of the crimes. Band is a term used to refer to certain First Nations communities in Canada.
Prime Minister Justin Trudeau called the attacks "shocking and heartbreaking" and said he had spoken with the leadership of the James Smith Cree Nation and Saskatchewan Premier Scott Moe to pledge his government's support.
"The federal government will be there with the resources necessary right now in this time of crisis but also we'll continue to work as partners in the weeks, months and years to come through grieving and healing," Trudeau said at the Ottawa airport, before flying to Vancouver for a meeting of Liberal ministers.
In an unrelated incident that has further rattled the province, police in Saskatchewan said on Monday they were investigating reports of a shooting on Witchekan Lake First Nation and warned the public that several armed suspects were on the loose.
