Two Virginia Tech students have been found murdered in a campground near the school, bringing fresh horror to a campus already rocked by tragedy, the Roanoke Times reports. Police have found no murder weapon, motive or suspect. They believe an attacker shot the sophomore couple in a "random act of brutal violence." Virginia Tech was the scene in 2007 of the massacre of 32 students and teachers. Earlier this year a student was beheaded by a male friend.
