Nannie Doss, otherwise known as the Giggling Granny, or Lady Bluebeard, was an elderly woman who poisoned and killed up to 11 members of her family, including four husbands. She blamed early head trauma and an unrealized dream of a romance novel-style marriage as the impetus behind her coldhearted murders, the crimes of Nannie Doss will shock even the most hardened true crime lovers.

Doss believed she deserved nothing less than a fantasy novel style partner, and if her husband didn’t measure up to that level, she killed him. Doss’s MO was varied, but mostly involved rat poison. She killed her four husbands using rat poison, but chose strangulation and a precisely placed hat pin to kill her grandchildren. She was never visibly upset or displayed any remorse. In fact, she was often smiling and giggling throughout her interrogations. Nannie Doss was a very wicked granny.
