Virgin killer's parents read his hate-filled manifesto then called the police and rushed to stop him when they heard of murder spree on their car radio

Elliot Rodger had emailed the 140-page document to a couple of dozen people including his parents and at least one of his therapists just hours before he went on his shooting rampage Friday night, family friend Simon Astaire told CNN. Lichin Rodger, the suspect's mother, reportedly received the email at 9:17 p.m. and immediately went on to her son's YouTube page where she found the newly uploaded video titled 'Retribution' in which describes his plan of 'slaughtering' women at a sorority house at the University of California at Santa Barbara. According to CNN, Mrs Roger then alerted her estranged husband, Peter, and after he watched the video they called 911 and set off to find their son. But they were too late.
