The Incredible Story of Juana Barraza, Mexico's Serial-Killing Pro Wrestler

It was a case that almost defied belief. From 1998 to 2006, someone in Mexico City was killing elderly women. Susana Vargas Cervantes, author of "The Little Old Lady Killer," told InsideEdition.com that the crimes "brought the nation into crisis." The police launched a hunt for the killer of old women, known in Spanish as "Mataviejitas." Ultimately and almost accidentally, they found a perp: a professional lucha libre wrestler named Juana Barraza.
