In the quiet foothills of Golden, Colorado, a grim discovery was made on the morning of April 7, 1984, near the serene Mother Cabrini Shrine. The body of 29-year-old Mark Edward Groezinger, a male resident of Golden, was found in his blue and white 1973 Buick. He had been shot multiple times in what investigators characterized as a crime of rage and passion. The driver's side window of his car was shattered, and his body was found slumped over in the front seat.
Investigators from the Jefferson County Sheriff's Department noted several peculiar details at the scene. While Groezinger's wallet and money were left untouched, his keys and some jewelry were missing. A paper bag containing. 38 caliber bullets was found on the floorboard of the car, and numerous shell casings were discovered both inside and outside the vehicle, suggesting the killer may have reloaded at least twice. The sheer number of shots fired led authorities to believe the murder was fueled by intense personal animosity.
The investigation soon focused on Mark's wife, Judy Groezinger. She and a family friend were reportedly the last to see Mark alive on the evening of April 6, 1984, when he mentioned he was going to a local bar to play pool. However, discrepancies emerged in Judy's account of that night when compared with witness statements. Authorities also learned that she had recently purchased a. 38-caliber pistol. Despite these suspicions and the circumstantial evidence, no physical evidence directly linked her to the crime, and she was never charged in connection with her husband's murder.
The murder of Mark Groezinger, a concrete coring company employee who enjoyed riding motorcycles and playing pool, remains an unsolved case that has puzzled investigators for decades. Despite being a person of interest, Judy Groezinger has consistently maintained her innocence. The case, which was once featured on the television show 'Unsolved Mysteries,' is now considered a cold case, leaving the questions of who killed Mark Groezinger and why unanswered.
