Canada: Authorities concluded suspect in last month's fatal stabbing massacre acted alone

Authorities say last month's fatal stabbing incident that killed 10 people in Canada was done by one person. Myles Sanderson killed eleven people, including his brother, Damien Sanderson. The Saskatchewan Royal Canadian Mounted Police originally thought both Sandersons may have been involved with the massacre, but it was later determined Damien Sanderson's injuries were not self-inflicted. His body was found a day after the stabbing incident that killed the ten others. Myles Sanderson was arrested shortly after the attacks but died while in custody.
