Jeffrey Dahmer murdered seventeen men and boys in Wisconsin between 1978 and 1991, most of the killings occurring in his Milwaukee apartment. He was arrested in July 1991 after a victim escaped and flagged down police.
The search of Dahmer's apartment uncovered evidence that led investigators to connect him to numerous missing-persons cases across more than a decade. The case drew significant public attention to gaps in how police had responded to earlier warning signs.
Dahmer pleaded guilty but mentally ill; a jury found him legally sane and he was convicted on all counts, receiving fifteen consecutive life sentences.
In November 1994, Dahmer was killed by a fellow inmate at the Columbia Correctional Institution in Wisconsin.
