A law enforcement official says the victim of a murder-suicide that locked down the UCLA campus for hours was a mechanical engineering professor.
William S. Klug was gunned down in an engineering building office Wednesday morning, according to the official who has knowledge of the investigation but wasn't authorized to publicly discuss it.
The shooter has not yet been identified.
Colleagues of Klug's said he was a married father of two and a kind, gentle person.
UCLA biology and chemistry Professor Charles Knobler said those who knew Klug are in shock. He described the professor as "a very lively, lovable, likable guy."
