In 1969, a seventeen-year-old girl, Mary Kay Heese, was brutally stabbed to death and left on a ditch near a road in Nebraska. For more than half a century the murder remained unsolved, but the cold case finally saw some developments when the U.S. Marshals arrested 77-year-old Joseph A. Ambroz from his home in Ponca city on November 18.
The authorities have not released any information on what led to the old man's arrest. But based on the very little information available on the case, Mary's body was exhumed in September of this year, which, according to reports, provided crucial evidence that led to Joseph's arrest on November 18 from Ponca City. He is charged with first-degree murder.
What happened to Mary Kay Heese in 1969?
Based on the New York Post report, Mary Kay Keese, a shy teenage girl from Wahoo High School, was seen with her friends having hot chocolate at a cafe after their track practice. She was also seen walking her way home, but Mary never returned home that night and was reported missing on March 25, 1969.
According to reports, the next morning a farmer came across Heese's school books scattered on a road three miles away from her hometown. The farmer passed on the books to the police station, and a police officer reached the scene along with the farmer. The police search of the area led them to discover the brutally stabbed body of Mary Kay Heese.
Mary Kay Heese's body had more than a dozen stab wounds on the stomach and she was missing her shoes. Based on the evidence, the investigators believe that on the day she went missing Mary got in the car of someone she's familiar with.
Based on the footprints found at the scene the police speculate that Mary might have tried running away from the attacker/ the car but was chased down and stabbed to death.
During the investigation, the police questioned more than 700 people, but they couldn't find a suspect and the case soon went cold. But, now the exhumed body of Mary may have reportedly provided enough evidence for an arrest warrant against Joseph.
Kathy Tulla, cousin of Mary Kay Heese, expressed her relief in finally having caught a suspect. She told First Alert 6,
"We kept calling state patrol. We kept calling and calling and calling, and where the case was with new evidence.” She added, "And when we put up our own tip line. That’s when things really took off."
Ambroz is held in a jail in Oklahoma and might have his first trial in the coming week.
