Edmund Kemper is one of the most brutal serial killers in American history, brutally killing ten innocent people, including his own grandparents and mother, in nine years, from 1964 to 1973. He was nicknamed "The Classmate Killer" because he specialized in hunting female college students in Santa Cruz County, California, who were tricked by him while hitchhiking on the road. Kemper not only killed them, but also raped, beheaded and dismembered their bodies, and even used their heads as sex toys. In 1973, he surrendered to the police, was sentenced to eight life sentences, and has since been imprisoned in a California medical facility prison.
Today, Kemper is still alive and 74 years old. He lived a quiet life in prison, sometimes interviewing journalists or psychologists in his office. He had the right to apply for parole, but he never really tried and knew he had no hope of freedom. Tall and burly, 2.06 meters tall and weighing 136 kilograms, he was one of the most high-profile inmates in prison. Even prison guards did not dare to despise him because he once strangled a serial rapist with his own hands.
