BackStory
Ed Kemper was the middle child of Edmund Kemper and Clarnell Kemper (Left; Edmund's Mother). His parents were divorced in 1957, and had to live with his two sisters and mother. Ed didn't have a good relationship with his mother because he was a constant reminder of her ex-husband. After the divorce she became an alcoholic and her social life dropped. She was in constant fear that Ed would rape his younger sister so to prevent this, his mother forced him to live in the basement (locked), isolated from his sisters.
As a child, signs of deviance (abnormal acts/behavior) were shown. He would cut off the heads of his sisters dolls and play a game he started called the "Gas Chamber" were he would blindfold them and pretend to suffer until they "died". Also, he would mutilate his cats or others by torturing them alive, burying them alive, decapitating them, and etc.
