In YouTube videos and a long written manifesto, Elliot Rodger aired his contempt for everyone from his roommates to the whole human race, reserving special hate for two groups: the women he says kept him a virgin for all of his 22 years, and the men they chose instead.
Authorities said he put that bitterness into action in a stabbing and shooting rampage Friday night 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.
Rodger then apparently shot and killed himself inside the black BMW he used in the violence, authorities said Saturday.
The rampage played out largely as he laid it out in the public postings, including a YouTube video where he sits in the BMW in sunset light and appears to be acting out scripted lines and planned laughs.
"I'll take great pleasure in slaughtering all of you," Rodger, the son of a Hollywood director who worked on "The Hunger Games," says in the video posted Friday and taken down by YouTube Saturday with a message saying it violated the site's terms of service.
"I don't know why you girls are so repulsed by me," he says in the video, describing his loneliness and frustration at never having had sex with or even kissed a girl. "I am polite. I am the ultimate gentleman. And yet, you girls never give me a chance. I don't know why."
Of the men he sees as rivals, he said: "I deserve girls much more than all those slobs," and that after his rampage "you will finally see that I am, in truth, the superior one, the true alpha male."
Sheriff Bill Brown, appearing on CNN on Sunday said that investigators are tying up a few ends, but "for the most part, I think, we have a pretty clear picture of what happened "
The first three killed Friday were male stabbing victims in Rodger's own apartment whose names have not been released, Brown said Saturday.
Then, at about 9:30 p.m., the citywide shooting and vehicle-ramming rampage began.
His first stop was the Alpha Phi sorority, which he had called "the hottest sorority of UCSB."
"I know exactly where their house is and I've sat outside it in my car to stalk them many times," Rodger wrote in his extensive manifesto titled "My Twisted World."
No one answered the door after one to two minutes of aggressive pounding, but he soon shot three women who were standing nearby, killing two of them, 19-year-old Veronika Weiss and 22-year-old Katherine Cooper.
He then drove to a deli where he walked inside and shot and killed another UC Santa Barbara student, 20-year-old Christopher Michaels-Martinez, the sheriff said.
"Chris was a really great kid," Michaels-Martinez's father said at a news conference where he choked back tears and eventually collapsed to his knees in agony. "Ask anyone who knew him. His death has left our family lost and broken."
Michaels-Martinez was the last one killed, but the rampage would continue as Rodger drove across Isla Vista, shooting at some and running down others with his car, twice exchanging gunfire with deputies. He was shot in the hip, but the gunshot to the head that killed him was thought to be self-inflicted, Brown said.
