Wisconsin has got to be one of the best states at producing serial killers, we have two of the most notorious and famous ones ever, also two of the absolute sickest ever...
Ed Gein "Upon entry to the shed on his property, they discovered Wordon's corpse, decapitated, hanging upside down by the ankles and split open down the torso like a deer. The mutilations had been performed post mortem; she had been killed with a close-range rifle blast.
Searching the house, authorities found severed heads acting as bedposts in the bedroom, skin used to make lampshades and chair seats, skullcaps made into soup bowls, a human heart in a brown paper bag beside the stove (often mistakenly believed to have been found in the frying pan), a necklace of human lips, a waistcoat made up of a vagina and breasts, and many more items fashioned from the parts of human bodies including a belt fashioned from nipples. Above all, Ed Gein's most infamous creation was an entire wardrobe fabricated of human skin consisting of: leggings, a gutted torso (including breasts) and an array of tanned, dead skin masks that looked leathery and almost mummified. All of these items were confirmed to be used as props for his late night rituals, in which Gein would dress himself as a woman and dance beneath the moonlight while banging pots and pans." Oh, he also performed necrophelia...
And Jeffrey Dahmer "Most of his victims were African American men who Dahmer subjected to sexual assaults. His main goal was for a completely compliant sexual partner, essentially making necrophilia his motivation for killing. He achieved notoriety after his arrest, following the discovery of several decaying bodies in acid vats in his apartment. Severed heads were found in his refrigerator and an altar of candles and human skulls were found in his closet. Accusations soon surfaced that Dahmer had practiced necrophilia and cannibalism. Dahmer admitted to eating the biceps of his eighth victim, noting that human flesh "tasted like beef" to him.
The explanation offered by Dahmer himself for his behavior was that he was attempting to remove the free will from his victims so that they would stay with him forever. Dahmer had experimented with removing sections of his living victims' skulls and pouring various chemicals into their brain cavities to try to create lobotomized zombies compliant to his wishes to fulfill his sexual desires."
