📖 Full Retelling
Seventeen-year-old Mary Kay Heese from Wahoo, Nebraska was found murdered on March 25, 1969, a week after she wrote a letter asking her cousin to accompany her to a Sadie Hawkins dance, with 77-year-old Joseph Ambroz finally arrested for the crime 55 years later in July 2025 after a renewed investigation. Mary Kay never returned home from school on that fateful day in 1969, and hours later, her body was discovered beaten and stabbed to death on the side of a road outside of town. Despite an initial investigation that led to two persons of interest—Joseph Ambroz and Wayne Greaser—the case remained unsolved for decades until a new investigation was launched in 2015 under criminal investigator Ted Green from the Saunders County Attorney's Office. Green pieced together Mary Kay's life, discovering she came from a strict home but desperately wanted to fit in at high school, which led to her asking her cousin Jerry to the Sadie Hawkins dance in a letter where she assured him she would pay for everything. Investigators concluded that Mary Kay, who wouldn't get into a car with strangers, likely knew Ambroz through a local café and mutual friends, believing he might help her socialize rather than seeing him as a threat.

48 Hours A Nebraska girl went looking for a date to a high school dance. One week later, she was murdered. By Michael Loftus Updated on: February 14, 2026 / 4:37 PM EST / CBS News Add CBS News on Google On March 25, 1969, 17-year-old Mary Kay Heese never returned home from school in Wahoo, Nebraska. Hours later, her body was found beaten and stabbed to death on the side of the road outside of town. Investigators tried to retrace Mary Kay's last known whereabouts. One witness saw Mary Kay get into a car with two men on a street corner near her home. But investigators at the time were unable to figure out who was in that car. Weeks turned into months with no arrests. Mary Kay's murder would remain unsolved for decades. "48 Hours" correspondent Natalie Morales reports on how the murder was finally brought back into focus in "The Girl from Wahoo," an all-new "48 Hours" airing Saturday, Feb. 14 at 10/9c on CBS and streaming on Paramount+. In 2015, a new investigation was launched. Ted Green, a criminal investigator with the Saunders County Attorney's Office, was assigned to the case. "Every criminal investigation is a puzzle," Green told "48 Hours." For Green, part of figuring out that puzzle was learning more about Mary Kay Heese. Mary Kay's younger cousins, Mark Miller and Kathy Tull, remember Mary Kay as a happy person who always looked out for them. But they said that happiness was sometimes challenged by the struggles of adolescence. Green learned Mary Kay came from a strict home under the eyes of watchful parents. It was a different situation at high school. "There was a group of girls that would get her together and put makeup on her at the beginning of the day and change her clothes out," Green said. "She wanted to fit in," Miller told "48 Hours." Part of that desire to fit in was Mary Kay's wish to attend the local Sadie Hawkins dance — a popular event at that time where the girls ask the boys to attend. Tull told "48 Hours" that the shy Mary Kay struggled to fi...
