UCSB shooter Elliot Rodger wrote a 140-page memoir-manifesto at some point prior to his murder spree that killed six. Along with the three people killed in the shooting spree, KEYT reported that three additional bodies have been found in Rodger's apartment, now identified as his roommates.

In the memoir, Rodger traces his life from his earliest memories to his plans for the Day of Retribution, a similar term he used in his last video that he called "Elliot Rodger's Retribution." The shooting wasn't his first act of violence against the peers he hated around him. According to the memoir, just prior to his 22nd birthday, he drunkenly got into a fight with some students at a UCSB party. He attempted to shove a group of both men and women off a 10-foot ledge because the women were not paying any attention to him. He ended up getting thrown off the ledge himself and was later beaten by students.

Rodger also mentions he was seeing counselors and social coaches and seemed optimistic about the help. Still, the memoir is peppered with his frustrations over women and his inability to understand why he was not receiving the attention he believed he deserved.

He begins talking in earnest about the Day of Retribution on page 124.

Rodger ends the memoir with some chilling statements.

"Why do things have to be this way. I’m sure that is the question everyone will be asking after the Day of Retribution is over. They will all be asking why? Indeed, why? That is the question I’ve had for everyone throughout all my years of suffering. Why was I condemned to live a life of misery and worthlessness while other men were able to experience the pleasures of sex and love with women? Why do things have to be this way? I ask all of you.

"All I ever wanted was to love women, and in turn to loved by them back. Their behavior towards me has only earned my hatred, and rightfully so! I am the true victim in all of this. I am the good guy. Humanity struck at me first by condemning me to experience so much suffering. I didn’t ask for this. I didn’t want this. I didn’t start this war… I wasn’t the one who struck first. But I will finish it by striking back. I will punish everyone. And it will be beautiful. Finally, at long last, I can show the world my true worth."

It hasn't been confirmed when Rodger penned the memoir and other details about the three bodies found in his apartment have not been revealed.
