In the spring of 1989, what was supposed to be a week of sun and fun for Mark Kilroy, a 21-year-old University of Texas student, turned into a horrific nightmare. While on spring break in Matamoros, Mexico, Mark vanished outside a bar, leaving behind a trail of unanswered questions. Initially, local authorities treated his disappearance as just another missing person case, but those who knew him sensed something far more sinister was at play.

As the investigation unfolded, a chilling tale of ritual sacrifice, drug smuggling, and unimaginable brutality emerged. Mark's family, friends, and volunteers worked tirelessly to uncover the truth, but it wasn't until nearly a month later that the shocking reality became clear. On April 11, 1989, Mark's body was found, along with 14 others, buried on a remote ranch. The mastermind behind this atrocity was Adolfo Constanzo, a sadistic cult leader who believed human sacrifices would grant his followers supernatural protection for their illicit activities.

Join me as I delve into the dark world of Constanzo's cult and the events that led to Mark Kilroy's tragic fate. This episode explores the twisted rituals, the international manhunt that followed, and the lasting impact of this case on the world. Discover how Mark's disappearance became a symbol of the horrors that lurk in the shadows of organized crime and cult violence. Will justice ever fully be served for Mark and the other victims of this heinous cult?
