Killer sent his chilling plans to parents

The parents of Britain-born Elliot Rodger desperately searched for him as he carried out a deadly gun and knife rampage in California, after they received his chilling manifesto, according to a family friend.

Rodger, 22, emailed a 140-page document to several people, including his parents and therapist, just before the shootings in the town of Isla Vista on Friday night, family friend Simon Astaire told CNN.

Rodger is believed to have shot himself in his car after killing six people with a gun and knife and fighting two gun battles with police.
