Preliminary tests found no signs of external trauma that could have caused the death of a mass stabbing suspect who died in police custody after one of Canada's deadliest mass violence incidents earlier in September, a coroner said on Wednesday.
Myles Sanderson, 30, and older brother Damien Sanderson, 31, were suspected of killing 10 people and wounding 18 others in a stabbing rampage in the James Smith Cree reserve and nearby village of Weldon in Canada's Saskatchewan province earlier this month.
