LUBBOCK, Texas – Texas Tech University officials have identified the suspect sought in the fatal shooting of a campus officer at the campus police headquarters.

A university statement identified the suspect as 19-year-old Hollis Daniels.

University spokesman Chris Cook says campus police made a student welfare check Monday evening and found upon entering the room evidence of drugs and drug paraphernalia. Cook says officers brought the suspect to the campus police station for standard debriefing.

During this time, Cook says the suspect pulled out a gun and shot an officer in the head, killing him. The suspect then fled on foot and is on the run. Tactical squad officers are assisting with the search.

University officials issued a lockdown alert to students on social media, noting that the suspect had not been apprehended. The alert urged those on campus “to take shelter in a safe location.”

Additional information was not immediately available.
