Virginia Tech officials confirm a police officer was killed during a traffic stop on campus, the suspect then ran to a parking lot and killed another person. WSLS reports the shooter remains on the loose.
BLACKSBURG, Va. -- A Virginia Tech police officer was shot to death Thursday and a second person found dead on campus was believed to have killed him, NBC News reported.
The officer was shot during a traffic stop, Virginia Tech spokesman Mark Owczarski told NBC News.
Police said the shooter was not in the car that was pulled over.
A second person also was found shot to death, and law enforcement officials believe he killed the policeman, NBC News' Pete Williams reported.
Officials at 4:31 p.m. EST lifted a warning that everyone should seek shelter. Normal activities could resume, the alert said.
Earlier, witnesses reported to police the shooter fled on foot from the traffic stop toward the Cage, a parking lot near Duck Pond Drive. At that parking lot, the second person was found dead, Owczarski said.
The Virginia Tech alert posted on the school's website described the suspected shooter as a white male wearing gray sweat pants, a gray hat with a neon green brim and a maroon hoodie, and carrying a backpack.
The alert said the suspect was last seen walking toward McComas Hall, which is the main gym on campus, about two blocks from Lane Stadium.
The shooting came the same day as Virginia Tech was appealing a $55,000 fine by the U.S. Education Department in connection with the university's response to a 2007 rampage.
In the deadliest mass shooting in U.S. history, 33 people, including the mentally ill gunman, were killed on the Virginia Tech campus on April 16, 2007. The massacre in a classroom building began at 9:40 a.m. when Seung-Hui Cho chained the doors and killed dozens before committing suicide.
