STORY: Burns, 62, a member of the community's crisis response team, was killed responding to a call for assistance at the James Smith Cree Nation.

"She passed away doing her job," Darryl Burns told Reuters.

Darryl Burns and his brother Ivor Wayne Burns, as well as others in the community, believe the stabbings might have been related to drugs and alcohol. Police have not identified drugs or alcohol as a factor.

Brothers Damien and Myles Sanderson are suspected of murdering 10 people and wounding 18 in a stabbing rampage that devastated an indigenous community in Saskatchewan on Sunday, in a country unaccustomed to outbreaks of mass violence.

Canadian police on Monday found one of the suspects in a mass stabbing spree dead while the other suspect, his brother, was still on the run and may be injured, officials said.
