MILWAUKEE (WKOW) -- 20 years ago Friday, police arrested Milwaukee's most notorious serial killer, Jeffery Dahmer.
The world found out on July 23, 1991, Dahmer had been arrested for killing 16 young men and boys in Milwaukee and one in Ohio. The chocolate factory worker admitted to the killings, after his last victim got away.
His murders were gruesome, involving rape and cannibalism.
On July 22, 1991, detectives zeroed in on Dahmer's second story apartment on North 25th Street, where he killed 12 of his 17 victims. The apartment building was torn down a year after the arrest and the lot remains empty to this day.
The city recently agreed to sell the property to the owner of an adjacent apartment building. City developers say it will be converted into green space
He was sentenced to life in prison in 1992, but another inmate killed him in 1994. Retired FBI profiler Neil Purtell worked on Dahmer's case. He tells WISN that very few killers disclose everything because holding something back is their power.
He says Dahmer spent time in Germany and Florida and he thinks it's possible there might be more victims. Dahmer's lawyer Gerald Boyle says he believes Dahmer revealed all his secrets, noting his confession was 159 pages.
