A Texas Tech University police officer has been shot and killed.

University spokesman Chris Cook said an officer was shot in the head Monday night and died.

The Associated Press identified the suspect as 19-year-old Hollis Daniels.

Cook said Texas Tech Police made a student welfare check Monday night. Upon entering the room, officers found evidence of drugs and drug paraphernalia.

Cook said officers brought the suspect into the police station for a standard debriefing. That's when the suspect pulled out a gun and shot one of the officers in the head.

Cook said the suspect ran from the scene, prompting a campus lockdown. The lockdown has since been lifted, and the suspect has been taken into custody, according to the university.

Houston Police Chief Art Acevedo, Gov. Greg Abbott and Sen. Ted Cruz, among others, tweeted about Monday night's fatal shooting.
