100 Murder Cases

Robert Berdella, the Butcher of Kansas.

In the late 80's, Robert Berdella tortured and killed six men, chopped their bodies into small pieces, and stuffed their remains into dog-food bags, according to The New York Daily News. He also kept detailed notes on each of his victims, which later helped investigators prove their murders. Berdella almost got away with it all. Had it not been for his seventh would-be victim, 22-year-old Christopher Bryson, who managed to escape from the second floor of Berdella's home, he may have not been caught.

Berdella was originally charged with sexual assault, but after police obtained a search warrant, they found human remains and other wallets of other victims. He was sentenced to life imprisonment and died of a heart attack in jail in 1992.
