Born on Halloween Day 1832, this woman was described by her childhood Sunday school superintendent as "a most exemplary and regular attender," "a girl of innocent disposition and average intelligence," and "distinguished for her particularly clean and tidy appearance". Did she grow up an artist or a serial killer?

Mary Ann Cotton, the woman in this photo, was an English killer who was put to death for the murder of her stepson Charles Edward Cotton. However, she is also believed to have killed up to 21 people, including three of her four husbands and 11 of her 13 children.
