Canada police: we may never know what motivated suspect Myles Sanderson

The suspect sought by Canadian police over Sunday's mass stabbing went into 'medical distress' shortly after his arrest and was pronounced dead at hospital, a Royal Canadian Mounted Police official says. Myles Sanderson, 30, was taken into custody near the town of Rosthern, Saskatchewan, about 100 km (62 miles) south-west of the area where one of the bloodiest acts of mass violence in the country's history unfolded on Sunday.
