Virginia Tech police officers console one another as they move toward the scene where a fellow police officer was killed in a parking lot on the campus of Virginia Tech, Dec. 8, in Blacksburg, Va. A man killed a police officer and another person after a traffic stop Thursday at Virginia Tech, sending a shudder through campus as students and faculty were told to stay inside and police searched for the gunman, school officials said.

Local S.W.A.T. team members congregate near a parking lot on the campus of Virginia Tech to look for an armed man who is suspected of killing two people, Dec. 8, in Blacksburg, Va. The school said a police officer pulled someone over for a traffic stop and was shot and killed. The shooter ran toward a nearby parking lot, where a second person was found dead. It was the first gunfire on campus since 33 people were killed in 2007 in the deadliest mass shooting in modern U.S. history. The deaths came on the same day university officials were in Washington appealing a fine that federal officials gave them over the school's response five years ago.
