About this episode
The shepherd saw everything—watched as El Chalequero dragged an elderly woman toward the Consulado River, pulled a knife from hisEpisode 11 of 15 | Season 36: Serial Killers in HistoryMexico City's first documented serial killer hunted working-class women for nearly three decades. This episode examines the systemic failures that allowed Francisco Guerrero Pérez to operate freely while authorities looked the other way.The Women History ForgotMurcia Gallardo was 47 years old when she died—a market vendor in La Merced who sold chilies and produce from the same corner stall she'd operated for over a decade. Her customers knew her voice calling out prices before dawn. She had three children and six grandchildren. Her daughter worked a stall two rows over.

When Francisco Guerrero Pérez was finally convicted in 1888, it was for just one murder despite evidence suggesting at least 20 victims.Content Warning: This episode contains descriptions of violence against women and sexual assault references.
