Goleta: 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.
They later learned their son had killed six people, wounded 13 and then - authorities say - took his own life.
The Los Angeles Times reported Sunday that mother Chin Rodger 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.
