Lonely hearts killer

Nanny Doss, born Nancy Hazel, in 1905, was an American serial killer who operated completely undetected for nearly three decades under the guise of a sweet, traditional homemaker.

Dubbed by the press as the Giggling Granny and the Lonely Hearts Killer, Doss took the lives of at least 11 people between 1927 and 1954. spanning multiple states, including Alabama, North Carolina, Kansas, and Oklahoma.

What makes her case so chilling is that her victim pool was comprised entirely of her own family members.

Her body count included four of five of her husbands, her mother, her sister, her mother-in-law, two of her own children, and two of her grandsons.
