About this listen

Mexico City—where bustling streets hide unspeakable secrets. Behind a gentle smile and government badge, Juana Barraza—known as La Mataviejitas—entered the homes of elderly women, offering help… and delivering death.

Once a professional wrestler, she used strength, precision, and a lifetime of buried rage to strangle her victims. Investigators searched for a male killer for years—until the shocking truth was unmasked. Beneath her calm voice and kind appearance lay trauma, betrayal, and a revenge so personal it rewrote the profile of a serial killer forever.

This episode dives into:

  • The emotional scars that shaped a murderer
  • How a mother’s betrayal turned into blood-soaked vengeance
  • Why no one suspected a woman — until it was too late
  • The twisted psychology behind control, trust, and hidden rage
