Wahoo, Neb. – After more than five decades, the cold murder case of Mary Kay Heese, a 17‑year‑old high‑school junior, is finally receiving a detailed public account. Former Saunders County investigator Ted Green, who spent ten years on the case, sat down with KETV reporter Carson DuRall to walk listeners through the tragic events of March 25, 1969.
Heese’s last known movements
According to Green, Heese said goodbye to her parents at home and attended school as usual. After classes she participated in a track meeting. “She’s coming home from this track meeting; she knows she has to go home,” Green recalled.
Heese typically walked home with her best friend, who lived nearby. Green said the friend dropped her off at an intersection near 12th and Linden streets, after which Heese walked alone. “This is the last place they’re seen, Mary Kay here on that corner,” Green said.
Possible abduction
Green believes that at that corner Heese entered a blue 1956 Chevrolet with two men. The vehicle was seen by a gas‑station attendant a short distance away. “That was a gas station back in the day, and the attendant there reported seeing two guys and a girl in a wide open blue ‘56 Chevy,” Green explained.
From the corner, the route to the gas station and then out of town would take only about thirty seconds. Green noted, “You’re out of town that quick.” He suggested that after getting into the car, Heese was taken onto back‑country roads where she vanished.
Reconstruction of the crime scene
Green described the murder scene as a minimally maintained road leading to a grove that was a known teen hang‑out at the time. He said, “She’s never made out with the guy. She’s very shy, so she’s getting nervous, and then when they get ready to make the turn, she’s like, ‘I’m putting my gloves on, I’m going to boogie.’”
Based on tire tracks and footprints, Green believes Heese fled the vehicle just before the car turned toward the grove. The evidence shows her purse and books near the turn, with footprints running opposite the car’s direction. “She’s running back this way. And as she’s running now, obviously he’s turned around trying not to run over her … We see the tire marks, and then he’s still chasing her,” Green said.
Footprint analysis suggests someone leapt from the car to pursue Heese. Green noted a brief set of shoe prints followed by a 41‑foot gap, indicating a struggle on the roadside.
Discovery of the body
Later that night, a farmer found Heese’s books near the scene. When police followed the farmer’s directions, they discovered Heese’s body in a ditch, bearing fourteen stab wounds.
Recent legal developments
On November 18, 2024, Joseph Ambroz was arrested in Oklahoma after a Saunders County grand jury indicted him for first‑degree murder. He entered a no‑contest plea to conspiracy to commit first‑degree murder on July 31, 2025, and was sentenced on August 27, 2025, to two years in prison – the maximum sentence allowed for the 1969 offense, with credit for time already served.
Ambroz served less than a year, benefiting from credit for time served while awaiting trial and Nebraska’s “good‑time” laws that reduced his sentence. He was released on November 15, 2025, and was home before the holidays.
Community reflection
The renewed focus on Heese’s case brings a measure of closure to a community that has long remembered the tragedy. While the conviction does not erase the loss, it underscores the persistence of law‑enforcement officials and the importance of revisiting cold cases to bring justice for victims and their families.
