Canadian police converged on the James Smith Cree Nation on Tuesday, drawn back to the area by possible sightings of the man wanted in a stabbing spree that killed 10 people, but the suspect remained at large in the third day of an intense manhunt.

CBC News reported a heavy police presence on the indigenous reserve in Saskatchewan, about 320 kilometers north of the provincial capital of Regina, where Sunday's bloodshed shocked a country largely unaccustomed to deadly bouts of mass violence.

Hours later, however, the Royal Canadian Mounted Police (RCMP) said its "investigation has determined" the suspect, Myles Sanderson, 30, "is not located in the community" of the reserve and that authorities were continuing to search for him.
