The Cleveland Torso Murderer
It’s hard to imagine a more miserable place than Cleveland during the Depression, but throw in a serial killer and geez... This murderer killed at least 12 vagrants and drifters between 1935-1938, many of whom lived in shanty towns and whose disappearances weren’t noticed. The victims were nearly all beheaded, dismembered, and in some cases, even castrated. Gruesome as he was, though, the killer was never identified or apprehended, despite the fact that Cleveland’s director of public safety at the time was none other than Eliot Ness.
Nannie Doss (aka the "Giggling Granny”)
Families are hard to deal with, even for most well adjusted of people. Nannie Doss, however, found a simple solution to her familial problems -- she just killed relatives she didn’t like. Of her 11 victims: four husbands, two sisters, a mother-in-law, a grandson, and even, well, HER OWN MOTHER. Typically using rat poison and arsenic, the “Giggling Granny” killed relatives with whom she disagreed; her last victim was husband Samuel Doss, whose life she ended with a poisoned “welcome home” meal after he was released from the hospital. She pled guilty to that crime in 1955, and died in prison of cancer 10 years later.
