JEFFERSON COUNTY, Colo. -- On April 6, 1984, Mark Groezinger told his wife, and one of her friends, that he was going out to play some pool at a local bar.
He didn't come home.
The next morning, deputies found a body in the front seat of a parked car at Mother Cabrini Shrine, just off Interstate 70 at highway 40.
The body they found belonged to Mark.
Police found him dead in his blue and white, two-door, 1973 Buick.
Investigators said Mark had suffered multiple gunshot wounds and that jewelry and keys were taken from his car.
He was 29-years-old when he died.
Mark worked in Denver for a concrete coring company and enjoyed motorcycle riding and playing pool at local taverns.
