College shooter Elliot Rodger blamed his hatred of women on a childhood crush who hardly remembers him.

Rodger identified the girl in the year below him at his Californian private school as the cause for his “intense fear of girls” in a 141-page manifesto.

Rodger became obsessed with now-model Monette Moio and claimed that being “teased and ridiculed” by her deeply wounded him.

In an interview with the New York Post, the girl’s father John Moio said that she only vaguely remembers Rodger and was too young to be as cruel as he claimed.

“She remembers him being odd, that’s it,” Mr Moio told the New York Post.

“He’s a sociopath. She hasn’t seen him since school,” Mr Moio said of Rodger.

“He called her a bully. She was just a little petite girl of just 10 years old.”

Prior to killing six people in California on Sunday, Rodger identified Moio as an “evil bitch” in the document titled “My Twisted World”.

“I hated her so much, and I will never forget her. I started to hate all girls because of this. I saw them as mean, cruel, and heartless creatures that took pleasure from my suffering,” wrote Rodger.

In the document he also claimed to be jealous of Moio’s older brother for being popular at school and an actor, “one of the most attractive careers a man can have”.

Rodger also allegedly told a friend prior to the shooting that he wanted to hold down and rape women, according to a report by The Herald Sun.

Cathleen Bloeser, whose son was a childhood friends of Rodger’s, told Mail Online that Rodger “wanted to get back at people”.

Rodger’s father Hollywood director Peter Rodger and his ex-wife called 911 after reading the manifesto on the night of the shooting, but did not arrive in Los Angeles until after their son’s rampage.
