SAN ANTONIO -- Police and college administrators Tuesday were searching for a motive in a shooting that claimed the life of a 37-year-old librarian at Northeast Lakeview College.

Eric Reno, the school's president, said that there appeared to be no problem between the shooter, Alan Godin, 62, and the victim, Devin Zimmerman, 37.

"I wish we had an explanation for why this happened, but we don't," Reno said.

Police said that Godin walked into the college's library at 2:15 p.m. Monday and fired four or five times at Zimmerman. Godin, who is also a librarian, then sat down and waited for police to arrest him. The suspect was charged with murder and was being held in the Bexar County Jail on $250,000 bond.

Derek Adair, a student at the community college, which is located in Live Oak, said that he and about 20 people who were in the library at the time ran for the nearest door after they heard the gunshots.

"People screaming, running, a lot of pandemonium," he said. "People just going every which way, just trying to get out before anyone else was shot."

Reno said he doesn't think that increased campus security would have prevented the incident.

"I don't know how anyone would predict something like this happening," he said. "This is not something you plan for or can prevent."

Students were shocked over the violence that happened at a place where most expect to feel safe.

"I think that's terrible," a male student said.

Classes were canceled Tuesday but counselors were available to talk with students about the incident.
