For a few hours this afternoon, the Virginia Tech campus in Blacksburg, Va., was on lockdown after two people, including a campus officer, were killed.
The school advised everyone on campus to "seek shelter or stay where you are," as police launched an all-out search for the gunman whom they described as a "white male" wearing "gray sweat pants, gray hat [with] neon green brim [and a] maroon hoodie..."
The university was the site of a mass shooting in April 2007, during which a student killed 32 other people before taking his own life.
Shortly before 5 p.m. ET., authorities said the situation on campus had been resolved. The AP reported the second person found dead was the shooter. During a press conference Sgt. Bob Carpentieri, of the Virginia State Police, said he could not confirm that report, but that "investigators feel confident they've identified the" shooter and they've recovered a weapon.
Charles Steger, the university's president, called the incident a "wanton act of violence." Steger said it was a "tremendous tragedy" that has been "very traumatic."
"It brings back some difficult memories of the past," said Steger.
According to police, the shooting happened after a police officer made a routine traffic stop at a school parking lot. Carpentieri said the shooter was apparently not the driver of the car, but instead a third person who walked up and shot the officer.
Dean Jessenger, chief of police for Virginia Tech, said that witnesses saw the suspect flee toward the location of a parking garage. Police responded and that's where police found the second body.
