Norma Jolene Madera, 27, was last seen at the Greyhound bus station in Yakima, Washington, on July 1, 1991. A member of the Confederated Tribes of the Colville Reservation, she was described as American Indian / Alaska Native, with brown hair and brown eyes, about five feet four inches tall and around 110 pounds. Norma planned to travel to Seattle and then continue south along Pacific Highway South toward Tacoma, but it was never confirmed whether she boarded the bus in Yakima.

Her multi-leg travel plan widened the area investigators had to consider and made it difficult to pin down where she might have disappeared. Authorities have had to consider possibilities ranging from an incident in Yakima before departure to something occurring in Seattle or en route to Tacoma. The Yakima Police Department continues to handle the case. If anyone remembers Norma, saw her at the bus station on July 1, 1991, or has information about her planned trip, please come forward.
