Warning: This episode is graphic. Listener discretion is advised.


It is a rite of passage for many American college students, and that is Spring Break. It’s a time when students can cut loose, drink too much, and make plenty of bad decisions. Whether Palm Springs or Palm Beach, kids flock to the surf, sun, and sand to have a week full of fun. As parents, we know our children are getting older, and we would probably prefer them not to go, but we have to trust them and know they will be ok but…what if the darkness that lurks out there is more evil than we could ever comprehend and it is just waiting for the right moment to strike.

On Wednesday, March 15, 1989, in Brownsville, Texas, two young men came into the station to talk to Chief Investigator George Gavito. The two men tell the investigator their good friend is missing as they explain that they are visiting South Padre Island for spring break. When investigators finally learn what happened to Mark Kilroy, it is indeed the stuff of nightmares.
