Jeffrey Lionel Dahmer, also known as the Milwaukee Cannibal or the Milwaukee Monster, was an American serial killer and sex offender who killed and dismembered seventeen males 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. Although he was diagnosed with borderline personality disorder (BPD), schizotypal personality disorder, and a psychotic disorder, Dahmer was found to be legally sane at his trial.
