Elliot Rodger, the shooter who killed six people near the University of California, Santa Barbara, or UCSB, Friday emailed his deadly plans minutes before he went on his murder spree, media reports said, citing two interviews on Sunday.

The 22-year-old son of a Hollywood director who worked on the first installation of the “Hunger Games,” stabbed three people, identified as his roommates, in his apartment before gunning down three more people Friday night near the UCSB campus in the town of Isla Vista. Authorities from the Santa Barbara County Sheriff’s office reportedly said that Rodger also wounded 13 people, including eight he shot as he tried to flee in his black BMW while exchanging fire with police. He then shot himself.

“The plan was to destroy the entirety of Isla Vista, and kill every single person in it, or at least kill as many popular young people I could before police arrived and I’d have to kill myself,” Rodger wrote in a memoir, which he emailed to about 30 people, including his father, mother and former teachers, Cathleen Bloeser, 58, whose son was a childhood friend of Rodger and was also included on the list, Reuters reported.

He reportedly said, in the document, that he first planned to kill his housemates, then lure other people to his residence and continue the killings before taking the lives of female students at a sorority house and other people on the streets of Isla Vista. According to reports, Rodger killed two women and four men, all of whom have been identified.

The victims were identified as George Chen, 19, one of his roommates and the first to be killed in the attack; Katie Cooper, 22, a senior at UCSB who was shot by Rodger across the street from the Alpha Phi sorority house; Veronika Elizabeth Weiss, 19, a water polo player at Westlake High School in Thousand Oaks, Calif., who was gunned down alongside Cooper; Christopher Ross Michael-Martinez, 20, who was inside the IV Deli Mart when Rodger opened fire; Cheng Yuan Hong, 20 and Weihan Wang, 20, two other housemates.

Bloeser told Reuters that Rodger had discussed sexual crimes with her 22-year-old son and another friend. "He'd changed emotionally and he'd become very despondent and he wanted to get back at people," she said. "I have a feeling that they would have been right there as a part of it and shot as well," she reportedly said, speculating that her son could also have been an intended target.

Simon Astaire, a family friend, told Reuters that Rodger’s therapist called his mother, Chin, on the night of the shooting, alerting her about the manifesto, following which she called the police and her ex-husband, Peter Rodger. He also said that Chin had heard radio reports about the shooting as she drove with Peter to Isla Vista.

Rodger traced his life from his earliest memories to his plans for the “Day of Retribution,” in the memoir, a similar term he used in the YouTube video, which he posted shortly before his deadly killing spree, called "Elliot Rodger's Retribution."

Santa Barbara County Sheriff Bill Brown told Reuters that Rodger was seeing many healthcare professionals and it was "very, very apparent he was severely mentally disturbed."
