About two hours after the first 911 call came in around 10 a.m., with the center of campus still saturated with officers, Los Angeles Police Chief Charlie Beck said it was a murder-suicide and declared the threat over. Two men were dead, and authorities found a gun and what might be a suicide note, he said.
William S. Klug, a professor of mechanical engineering, was gunned down in an engineering building office, according to a law enforcement official. The official has knowledge of the investigation but wasn't authorized to publicly discuss it. The shooter has not yet been identified.
