In the autumn of 1983, a young life was tragically cut short, leaving a void in the lives of her loved ones and a mystery that would haunt a community for decades. Terri McCauley, an 18-year-old female and a member of the Omaha Tribe of Nebraska, disappeared after a night out with friends in Sioux City, Iowa, in late September. She was a mother to two young children and was described by her family as outgoing and someone who loved people.
The last time her friends saw her, she was getting into a vehicle with a man outside of a bar on the west side of the city. As days turned into weeks with no word, concern grew into a desperate search for answers.
On October 6, 1983, the search came to a grim conclusion when a person walking their dog discovered Terri's body in a wooded area miles from where she was last seen. An autopsy would later reveal that she had died from a shotgun wound to the face. The initial investigation into her death yielded few leads, and despite the efforts of law enforcement at the time, the case grew cold. For years, her family was left with unanswered questions and the pain of not knowing who was responsible for her death. Advocacy groups, particularly those focused on Missing and Murdered Indigenous Women and Relatives, worked to keep her story alive, refusing to let her be forgotten.
For over four decades, the case remained unsolved, a lingering injustice for Terri's family and community. A retired Sioux City police detective who had worked on the original investigation had recommended a suspect be charged shortly after the murder, but the county attorney at the time felt there was not enough evidence to secure a conviction. However, persistent police work and the unwavering hope of her family finally led to a breakthrough. In January 2025, a grand jury indicted 62-year-old Thomas Duane Popp on a charge of first-degree murder. Popp was subsequently arrested in Washington state and awaits extradition to Iowa to face trial, bringing a long-awaited sense of potential closure to a case that had remained open for more than 40 years.
