“The Little Old Lady Killer” is a Mexican former professional wrestler who allegedly killed between 42 and 48 women from the 1990s and early 2000s.

Barraza would pretend to be a nurse or social worker to elderly women and then strangle them with items found in their houses. She would go on to steal religious artifacts from them.
