Ripper Crew or Chicago Rippers was a satanic cult and organized crime group composed of Robin Gecht (who once worked for the serial killer John Wayne Gacy) and three associates (Edward Spreitzer with brothers Andrew and Thomas Kokoraleis). They were suspected in the disappearances of 18 women in Illinois in 1981 and '82.

Edward Spreitzer-Leader of the infamous "Ripper Crew" (AKA "The Chicago Rippers")  Often choosing prostitutes as victims, but occasionally branching out towards women who were in "the wrong place at the wrong time", Edward and his crew claimed 18 victims while cruising urban areas in their van. Every victim had her breasts severed from her body, and almost every victim was was brought back to Edward's apartment, where all the crews members would masturbate onto the victims mutilated bodies while having verses from The Satanic Bible read to them. The Ripper Crew would also eat pieces of the severed breasts to "finalize" their rituals. Spreitzer is serving live in prison for the murders.
