Jeffrey Lionel Dahmer, The Milwaukee Cannibal
He is an exception. He was a child loved by his parents who had a good education and a happy social life. He is responsible for the deaths of 17 men and boys, between 1978 and 1991. He is known not only for the number of people he killed, but also for practicing necrophilia and cannibalism.His strategy was recurring: he invited men to pose for some pictures, put drugs in their drinks, strangled them and had sex with them. Then, he photographed the bodies and he also took pictures detailing their dismemberment. He used acids to dissolve the bodies, but kept their head and genitals as trophies. In May 1991, he made some burr-holes in the skull of a 19-year-old boy to inject acid in his brain. But the boy escaped, running naked through the streets, prompting neighbors to alert the police. The boy could not speak because he was in shock. Dahmer claimed that the young man was his lover and that he was drunk. The murderer managed to confuse the police, who found no proof. On July 22, 1991, another young man escaped in handcuffs. The police decided to make further investigations. They found photographs of corpses, human remains and a head in the refrigerator of his house. Dahmer tried to escape but was arrested. The jury declared him sane and sentenced him to 15 consecutive life terms. He died during a fight in the Portage prison.
