Santa Monica shooting suspect ID'd; father, brother among victims

Santa Monica, California (CNN) -- The suspect in a shooting spree that left four people dead in Santa Monica has been identified as John Zawahri, sources told CNN.

Authorities say he killed his father, Samir "Sam" Zawahri, and brother, Chris Zawahri, in a Santa Monica house before carjacking a woman and firing at a public bus on Friday.

Scant details are trickling in about Zawahri, who was killed by police at Santa Monica College on Friday -- the day before his 24th birthday.

The superintendent of the Santa Monica-Malibu school district said Zawahri attended a high school for students behind in academic credits in 2006.

A law enforcement source with knowledge of the investigation told CNN on Saturday that the gunman had suffered mental health issues. A few years ago, he was hospitalized for treatment after allegedly talking about harming someone, according to the official.
