Canada’s largest manhunt extended into its third day on Tuesday with hundreds of officers searching for the lone surviving suspect in a stabbing spree that killed 10 people on Sunday, roiling a country where mass violence is rare. Myles Sanderson, 30, remained on the loose and possibly injured, police said, after they found his brother Damien Sanderson, 31, dead in a grassy area of the James Smith Cree Nation in Saskatchewan on Monday. 

The brothers are suspected of murdering 10 people and wounding 18 more in a stabbing rampage that devastated an indigenous community in one of the deadliest attacks in Canada’s modern history. Police said some of the victims appeared to have been targeted, while others were apparently random.
