Details of Disappearance

Medicine Horse was last seen in the front yard of her uncle's residence in Crow Agency, Montana on September 28, 1981. She dropped her father off there, then drove away in her white car. She has never been heard from again.

She was not reported missing immediately because she had a history of alcohol abuse and dropping out of sight. Her sisters reported her missing after their mother died on October 23, almost a month after Medicine Horse was last seen, and she didn't show up for the funeral.

Little information is available in Medicine Horse's case, but her children still hope for answers in her disappearance.
