A Texas Tech student brought to the university's police station for a welfare check shot and killed an officer on Monday night.
Following the shooting he fled from the police station prompting officials to lock down the campus and urge students and staff to take shelter. He was however apprehended later and the lockdown lifted.
Police had found "evidence of drugs and drug paraphernalia" in the student's room, the university told the student newspaper the Daily Toreador. After officers brought the student to the police station, that student pulled out a gun and shot one officer in the head, officials said.
The suspect was described as 6 feet tall and 140 pounds with blue eyes and red hair, wearing blue jeans and a white T-shirt.
