Jeffrey Lionel Dahmer (/ˈdɑːmər/; May 21, 1960 – November 28, 1994), also known as the Milwaukee Cannibal or the Milwaukee Monster, was a convicted American serial killer and sex offender who committed the murder and dismemberment of 17 men and boys between 1978 and 1991. Many of his later murders involved necrophilia, cannibalism, and the permanent preservation of body parts—typically all or part of the skeleton. On November 28, 1994, Dahmer was beaten to death by Christopher Scarver, a fellow inmate at the Columbia Correctional Institution in Portage, Wisconsin.
