Jeffrey Lionel Dahmer, born on May 21, 1960, was an American serial killer and sex offender, infamously known as the Milwaukee Cannibal or the Milwaukee Monster. His heinous acts spanned from 1978 to 1991, during which he murdered and dismembered seventeen men and boys. Dahmer's criminal journey began in Ohio with his first murder in 1978, but he did not continue his killing spree until nearly a decade later in 1987.
Many of Dahmer's later crimes involved a disturbing pattern where he would lure victims to his apartment in Wisconsin. Once there, they would be drugged, sexually assaulted, and ultimately murdered. His gruesome methods included necrophilia, cannibalism, and the preservation of body parts, often retaining all or parts of the skeletons of his victims.
In 1991, Dahmer's reign of terror came to an end when one of his intended victims managed to escape and alert the authorities. Despite being diagnosed with borderline personality disorder, schizotypal personality disorder, and a psychotic disorder, he was deemed legally sane during his trial. In 1992, he was convicted of sixteen counts of murder, receiving a sentence of life imprisonment without the possibility of parole.
On November 28, 1994, Dahmer's life ended violently when he was beaten to death by fellow inmate Christopher Scarver at the Columbia Correctional Institution in Portage, Wisconsin. His life and crimes continue to evoke horror and fascination, marking him as one of the most notorious figures in American criminal history.
