Two people, including a campus police officer, were shot and killed on the campus of Virginia Tech U. just after noon on Thursday. The shooter has not yet been found.

The school posted an alert on www.VT.edu, confirming the deaths.

According to the school’s report, the incident started with a routine traffic stop in the parking lot near the Coliseum, the school’s basketball arena. During that traffic stop, the police officer was shot and killed.

Witnesses reported the shooter running away from the scene, toward another parking lot, near Duck Pond Drive. Police found a second person dead at that parking lot. Police have not made the identity of either of the victims public at this time.

The shooter is described as a white male wearing gray sweat pants, a gray hat with a neon green brim, a maroon hoodie and a backpack.

Virginia State Police have now taken over the investigation.

Virginia Tech has advised students and faculty to stay indoors in secure areas, and warned visitors not to come to campus. The school also canceled final exams scheduled for Friday.

There is a media briefing now scheduled for 4:30pm on campus.

The incident is a terrifying reminder of the 2007 shooting rampage on campus that left 33 people, including the shooter, dead. That was the deadliest shooting rampage in modern U.S. history.

In that case, Seung-Hui Cho chained the doors of a classroom building closed on April 16, 2007 and killed 32 people before committing suicide.
