Mary Ann Cotton: The English murderess is believed to have poisoned to death 21 people by arsenic in the 1800s.  Cotton’s victims included her mother, children, husbands, a friend and a boyfriend—and she profited by inheriting their estates or receiving money from life insurance policies.  Cotton was convicted of the murder of her stepson after his body tested positive for arsenic.  The British woman staunchly professed her innocence, claiming he died from arsenic in the wallpaper, but she was found guilty.  Cotton’s 1873 hanging was botched, resulting in a slow and painful execution.

Marie Noe: In 1999, this Philadelphia woman was convicted of murdering eight of her ten children between 1949 and 1968.  The deaths had been blamed on sudden infant death syndrome, but after a journalist investigated Noe’s case in 1998, she confessed she’d smothered her kids.  Noe pleaded guilty to eight counts of second-degree murder and was sentenced to 20 years of probation.  Her husband Arthur never believed she was guilty. "I've lived with this woman for 50 years. She wouldn’t hurt a fly," he claimed. Arthur died in 2010 of natural causes; Marie is now 85.

Myra Hindley: From 1963 to 1965, the “Moors murders” of five children between 10 and 17, who had also been sexually assaulted, shocked England.

In recently released prison files, the public found out Hindley had admitted she was more “culpable” than Brady because she “knew the difference between right and wrong.”

Dorothea Puente: The Sacramento, Calif. woman rented out rooms to the elderly for years; and the only thing that troubled her neighbors was a persistent stench emanating from her yard. No wonder.

They found boarders’ remains all over Puente’s property and also discovered she had cashed their social security checks. She got life in prison for multiple murder and died in jail in 2011, still claiming her innocence. It’s been estimated Puente killed 3-9 people.
