GOLETA, Calif.-- A man identified as, Elliot Rodger, went on a stabbing and shooting rampage across the seaside California college town of Isla Vista that killed two young women and four men, at least half of them students at the University of California, Santa Barbara. Thirteen people were injured.
The Santa Barbara sheriff's office said Sunday that the victims were 20-year-old Cheng Yuan Hong and 19-year-old George Chen -- both from San Jose -- and 20-year-old Weihan Wang of Fremont.
The three UC Santa Barbara students were the first killed in Friday night's rampage.
Hong and Chen are listed on the lease as Rodger's roommates. Investigators were trying to determine whether Wang was also a roommate or was visiting the night of the killings.
Elliot Rodger's parents raced to his Santa Barbara-area community after his mother saw his online threats, but they heard the news of a shooting on the radio as they were driving on the freeway.
Rodger was the son of a Hollywood director who worked on "The Hunger Games."
Chin Rodger, Rodger's mother, got a call from her son's therapist shortly before the shootings Friday about a ranting email sent by their son.Then the mother found his video vowing to kill people.
Family friend Simon Astaire tells the newspaper that Chin Rodger alerted authorities and set off with her ex-husband, director Peter Rodger.But by the time they arrived, officers confirmed their son had gone on a rampage.
A semi-automatic handgun was recovered from the scene near the University of California, Santa Barbara. Rodger apparently shot and killed himself inside his black BMW he used in the violence.
The Internet videos posted by Elliot Rodger are filled with threats and bitterness, but sheriff's deputies didn't become aware of them until it was too late.
Santa Barbara County Sheriff's Office spokeswoman Kelly Hoover says the agency "was not aware of any videos" until after Rodger went on beach-town rampage that left six dead and 13 wounded.
Deputies visited Rodger last month after being alerted by local health officials, who had been in touch with the family. They concluded he posed no threat.
It's not clear why the sheriffs did not see the videos.
