Diane Lynn Medicinehorse, a 26-year-old Native American woman, was last seen on September 28, 1981, in Crow Agency, Montana. That day, she dropped her father off at her uncle’s residence before driving away in her white car. Despite this being the last confirmed sighting, she was not immediately reported missing. Due to her history of alcohol abuse and periodic absences, her disappearance was not considered unusual at first.
However, concerns escalated when she failed to attend her mother's funeral on October 23, 1981, at which point her sisters reported her missing.
Medicinehorse, who went by the nickname "Tiny," had struggled with alcohol addiction throughout her life, which deeply affected her relationships and lifestyle. Her case remains unsolved, with little information available on what might have happened to her after she drove away that September day. The lack of evidence, combined with systemic issues around missing Indigenous women, has made finding answers difficult for her family, who continue to search for closure decades later. Law enforcement agencies, including the Bureau of Indian Affairs, continue to investigate her case.Last Seen: Sep 28, 1981
