On Saturday the Oregon state medical examiner’s office ruled that Chris Harper-Mercer, the shooter who killed nine people and injured more than a dozen others at Roseburg's Umpqua Community College last Thursday, died by his own hand and not as the result of a shootout with police, as some initially surmised. Despite being heavily armed, the 26-year-old apparently turned one of his weapons on himself rather than engage the police in a firefight
