Spring Break 1989. Thousands of college students flood the Mexican border town of Matamoros for nights of partying and cheap drinks. Among them is Mark Kilroy, a 21-year-old pre-med student from Texas. But by morning… Mark has vanished without a trace.

What begins as a missing person case soon unravels into one of the most shocking true crime stories of the 1980s — a narco-satanist cult, ritual human sacrifice, and a manhunt that would end in bloodshed in Mexico City.

In this episode of The Ritual Rewind, we uncover:

🔸 Mark Kilroy’s abduction during spring break

🔸 The twisted rituals at Rancho Santa Elena

🔸 The cult led by Adolfo Constanzo and Sara Aldrete

🔸 The discovery of 13 bodies and the terrifying truth behind the nganga

🔸 The violent standoff that ended Constanzo’s reign of terror

This is the story that blurred the line between cartel crime and black magic—and shocked the world.
