#22 – Edmund Kemper
Edmund Kemper is one of the most horrifying serial murderers in the American history. Nicknamed “The Co-Ed Killer,” he carried out eight gruesome murders in California during the 1970s. The Co-Ed’s first victims were his grandparents, whom he had murdered when he was only 15 years old.
After slaughtering his grandparents at such a young age, Edmund had a strong desire for more blood so he murdered and dismembered several female hitchhikers in the vicinity of Santa Cruz. Kemper’s last victims were his mother and a friend of hers. He was sentenced to life imprisonment for his terrible crimes.
