One of the nation’s most……notorious serial killers, Jeffrey Dahmer was born and raised in Bath Township, Ohio, a middle-class suburb of Akron.Much has been made of his childhood tendencies - including cases of cruelty to animals - but to outward appearances, atleast, he seemed to be a normal child. As an adult he was always gainfully employed and was perceived as quiet andpolite by co-workers.
At the time of his arrest he had been working at a chocolate factory in Milwaukee and living alone in a small one-bedroomapartment. Dahmer's home was searched on July 22, 1991, after a young man fled his apartment and flagged down apolice car. An investigation revealed that the apartment contained the remains of 11 young men, most of them black,Hispanic, or Asian. The bodies had been dismembered, and Dahmer confessed that he had cooked and eaten some of theremains. Asked why he committed such heinous acts, Dahmer told police that he killed because he was "lonely" and didnot want his victims to leave him. He explained that he would meet potential victims in bars, shopping malls, or adultbookstores, and invite them back to his apartment where, in exchange for money or beer, he would photograph themnaked. He would then drug the beer and, once the victim was unconscious, strangle and dismember the body. Dahmer'svictims ranged in age from 14 to 33.
On February 15, 1992, Dahmer was found guilty on 15 murder counts in Wisconsin. He was subsequently convicted ofanother killing in his Ohio hometown. Charges linking him to other murders were dropped for lack of evidence. He wassent to prison in Wisconsin with 15 mandatory life sentences to serve. The first year of his sentence, Dahmer was isolatedfrom the general prison on population for his own protection. In 1994 he was sent to a maximum security facility in Portageand was allowed some contact with the other inmates. He died after a brutal bludgeoning attack on November 28, 1994,by a fellow inmate who claimed God had instructed him to murder Jeffrey Dahmer.
Even after Dahmer's death, legal battles continue over his estate. Several families of his victims sued him and wereawarded millions of dollars in restitution. Those families have since been trying to gain control of the contents of Dahmer'sapartment, including a 55-gallon vat he used to decompose bodies and the refrigerator where he stored his victims' hearts.
