McCauley, a young mother of two and member of the Omaha Tribe, was last seen alive getting into a white Chevy Nova in a Sioux City parking lot in the early morning hours of Sept. 26, 1983. Before climbing into the car, McCauley told the two friends she was with that she was going on a date, the Register previously reported.
