What was going on inside the mind of Elliot Rodger, the young man who killed six people, Santa Barbara, California?
One survivor of the rampage who was shot five times outside her sorority house tells ABC News she will never forget Rodger's smirk - just before he opened fire, killing two of her friends.
"I see his face, he smiles at me and then he starts shooting," she said. "He was just he wanted to do this, he looked happy about it."
The Santa Barbara County Sheriff's Department is facing questions about whether they missed an opportunity to stop the rampage.
Police were aware of Rodger's disturbing videos when they spoke to him last month during a welfare check.
But as Sara Sidner reports, they never watched the videos.

Unfortunately, the mental health system in this country is horrible. I have a brother who suffers from schizophrenia and cannot receive the help he needs until at some point he hurts himself or others. You can second guess pretty much anything but I do not believe that there was any problem with the way the authorities handled the situation prior to the shooting. I keep hoping incidents like this will trigger some sort of reform in the way this country treats people with either diagnosed or suspected mental illness. I guess as soon as there is money in it we will move back toward the treatment side.
