Spring Break Murder: The Killing of Mark Kilroy
In 1989, Mark Kilroy, a student at the University of Texas, went on spring break in Mexico with a group of friends. While there, he was abducted and taken to a ranch in the middle of nowhere. He was tortured and sodomized for hours before being killed in a human sacrifice ritual.

His killers, members of a drug-trafficking cult led by Adolfo de Jesus Constanzo, decapitated him with a machete and removed his brain, which they boiled in a pot. They then inserted a wire through his spinal column, amputated his legs at the knees, and buried him on the ranch's property along with 14 other bodies.
The cult leader told his followers that they had to commit these murders in order to gain immunity for their drug crimes. When police showed up on the property, they found Mark's grave marked by a wire sticking out of the ground.
The cult had buried him this way so they could easily extract his bones from his decomposing body after they had decomposed. They planned to wear the bones as jewelry.
When police surrounded the cult leader's apartment complex, he realized he was caught and ordered his followers to execute him with a machine gun.
Mark Kilroy's murder was a horrific crime that shocked the world. It also led to a crackdown on drug trafficking in Mexico and a greater awareness of the dangers of human sacrifice rituals.
