90: Mark Kilroy: Matamoros, Mexic

Mark Kilroy was a bright, athletic college student - a pre-med major with a promising future. Blowing off steam on a spring break getaway to the sun-drenched border town of Matamoros, Mexico.
But somewhere between the neon-lit bars and crowded streets, Mark vanished without a trace.
At first, it looked like another spring break gone wrong - just a kid who wandered off. But what investigators would uncover over the next few weeks was darker, stranger, and more terrifying than anyone could have imagined.
Buried in the desert was a secret ranch… A bloodstained altar… And the remains of a human sacrifice performed by a cult that believed death could make them invisible to law enforcement.
This isn’t just a story of murder. It’s a story of black magic, cartel power, and how one young man’s disappearance unraveled a ritualistic killing spree that shocked the world.
Listen as we dive into Mexico, the case of Mark Kilroy, and how to stay alive on vacation.
