A gunman killed four people in Santa Monica before heading to the library at Santa Monica College, where authorities shot and killed him, The Los Angeles Times reported. His motive was not clear, but authorities said that they believed he had mental health issues and was upset over the divorce of his parents. Chui L. Tsang, president of the college, stressed in a statement that the incident was "not a school shooting," but an incident off-campus that happened to end on campus. Even so, the impact of the incident on the college extended beyond what took place on the campus. The Times reported that one of those killed off-campus was Carlos Navarro Franco, who for 22 years worked as a groundskeeper at the college. He was killed while driving his daughter -- a student there -- to campus to buy books. She was also shot and is in critical condition.
