The Santa Barbara County Sheriff's Office said the man suspected of a shooting rampage that left six dead near the University of California, Santa Barbara, is 22-year-old Elliot Rodger.
Sheriff Bill Brown had earlier on Saturday said a YouTube video titled "Elliot Rodger's Retribution" was connected to the crime.
In it, Rodger is sitting in a parked car with the sun low on the horizon. He talks about his frustration with women and says that at age 22, he was still a virgin.
"You never showed me any mercy, so I will show you none," he says, laughing. "I'll give you exactly what you deserve — all of you. All you girls who rejected me and looked down upon me and treated me like scum, while you gave yourself to other men. And all of you men for living a better life than me. All of you sexually active men. I hate you."
Rodger warns that this will be his last video and that he will "slaughter every single one of you."
Rodger seems to have left a vast digital trail. On his YouTube channel, for example, he uploaded multiple videos musing on his loneliness.
One video is titled, "Why do girls hate me so much?"
He wonders why it is that someone who owns a nice car, expensive glasses and is the "ultimate gentleman" cannot attract girls.
"I'm so magnificent. I deserve girls much more than all those slobs I see in my college, who are somehow able to walk around with beautiful girls," he says.
In a video uploaded on May 1, he writes: "I temporarily took all of my Vlog's down due to the alarm it caused with some people in my family. I will post more updates in the future."
A user who calls himself Elliot Rodger and uses the same picture, also posted to a bodybuilding message board expressing the same regrets.
Journalist Matthew Keys took a screen shot of one of the threads, in which he says "feminism is evil."
"Women have control over which men get sex and which men don't, thus having control over which men breed and which men don't," the user writes. "Feminism gave women the power over the future of the human species. Feminism is evil."
On what appears to be his Google Plus profile, Rodger says that he was born in Britain and moved the U.S. at age 5. He writes that he is currently attending college at Santa Barbara City College, Moorpark College.
"I have tried very hard to fit in with the social scene there, but I have ultimately been unable to do so," he writes. "There are too many obnoxious people who have ruined my whole experience at that place."
What appears to be his Facebook profile is full of selfies that show an extravagant lifestyle — plane rides and movie premieres. There's also a picture uploaded on April 8, where a stern-looking Rodger poses with his father amid blooming flowers.
