The site said Crouse joined the campus Police Department on Oct. 27, 2007, and served in the patrol division. He had been a member of the force's Emergency Response Team since February, and in 2008 he received an award for his commitment to the department's efforts against driving under the influence.

He was an Army veteran who had worked at the New River Valley Jail and the Montgomery County Sheriff's Department.

The gunman thought to have killed Crouse was found dead on campus with a gunshot wound.
