Virginia Tech says a police officer and a second victim have been shot and killed on the campus, where 32 students and faculty died in a 2007 rampage that was the deadliest mass shooting in modern U.S. history.
Authorities are seeking a suspect at the Blacksburg, Va., university. A campus-wide alert tells students and faculty to stay inside and lock doors.
A law enforcement official, who spoke on condition of anonymity because he was not authorized to discuss the case, said initial reports indicated that the shooting occurred following a traffic stop.
The suspect is described as a white male wearing grey sweat pants, grey hat with neon green brim, maroon hoodie and backpack.
