SAN ANTONIO -- A 37-year-old employee of Northeast Lakeview College was shot and killed in the campus library Monday afternoon by another employee, said Kay Hendricks, coordinator of communication for the college.

The victim was identified as Devin Zimmerman, a fulltime librarian at the college.

The gunman, 62-year-old Alan Godin, a part-time librarian, was arrested, Hendricks said.

Police and college administrators were searching for a motive in the shooting, which happened at 2:15 p.m.

The campus, which is located in the 8300 block of Pat Booker Road, canceled classes at both campuses Monday and Tuesday.

"This is a terrible tragedy for which no motive has been established," Hendricks said. "Our hearts, sympathy and condolences go out to family members of the victim."
