Introduction Edmund Kemper is one of the most famous serial killers, since he was mentioned in various popular shows and movies because of the cruelty of his crimes. The men murdered ten people, including grandparents and mother, and called the police to report about his crimes (Tallerico, 2017). Although the actions of the serial killer indicate deep mental problems, the causes of the occurrence are also important. Consequently, this article will examine the biography of Edmund Kemper, as well as the history of his murders, to find the reasons for his terrible crimes. Childhood A person’s childhood has a significant influence on the formation and prediction of his or her adult life. Ed Kemper had a difficult childhood and has been showing alarming signs from an early age. He was born in Burbank in 1948, and after his parents split up, he lived with his mother and sister (Greig, 2017). Kamper was gloomy and aggressive, loved violent games, and abuse animals. In an interview, he said that he and his sister were playing “a gas chamber or an electric chair,” and, once, he buried their cat alive in the garden (Serial Killers Documentaries, 2017).
