Edmund Kemper was found guilty of the murders of six young women, his two grandparents, his mother and mothers friend. Kempers killing spree and cannibalism was believed to be the result of his disdain for his mother and an unhappy childhood. According to Kemper, his mother psychologically abused him and at one point forced him to sleep in the cold and dark basement when he was a child. While in the basement, his hate for his mother began to fester. In order to release the pent up anger he would often entertain murderous fantasies.
