Ballistics evidence testing showed that the two shootings that occurred yesterday on the Tech campus are linked, with both individuals being shot with the same weapon.

At this time, there is no connection or prior contact between Ashley and Crouse. State police are still working toward establishing a motive in the murder.
Ashley is also allegedly responsible for the hijacking of a white 2011 Mercedes SUV from a real estate office that occurred in Radford on Wednesday, Dec. 7, according to State police. The SUV was stolen at gunpoint at about 11:25 a.m. Wednesday from Gilbert Real Estate on the 600 Block of Calhoun Street.
