Road Trip: Los Satanicos — The Murder of Mark Kilroy

Episode 412: In March 1989, 21-year-old University of Texas pre-med student Mark Kilroy travelled to South Padre Island with friends for spring break. One night, they crossed the international bridge from Brownsville, Texas, into Matamoros, Mexico, for drinks and a night out. In the early hours of March 13, as the group headed back toward the United States, Mark was briefly left standing alone near the roadside. When his friends turned back moments later, he had vanished. At first, they assumed they had simply become separated in the crowds, but Mark never returned. His disappearance triggered an urgent search on both sides of the border that would soon uncover something far more disturbing than anyone imagined, a discovery that exposed a hidden world of violence and horror behind one young man’s spring break trip.
