In this episode, we dive into the disturbing case of Juana Barraza, one of Mexico’s most notorious serial killers. Known as “La Mataviejitas”—The Little Old Lady Killer—Barraza preyed on elderly women across Mexico City for years, blending in as a nurse, social worker, or caregiver. Her crimes shocked the nation and exposed deep systemic failures in law enforcement, profiling, and the protection of vulnerable populations.
