Tucker was last seen in Clallam County, Washington on December 31, 1990. She was separated from her husband at the time and living with a boyfriend at the Elwha River Resort off U.S. Highway 101. Her boyfriend went to sleep that night, and Tucker apparently went for a walk. She was last seen on the Elwha River bridge. She was apparently intoxicated and despondent. She has never been heard from again. Her boyfriend reported her missing on January 5.

Tucker did not have access to a vehicle, and temperatures in the area were below freezing on the night she vanished. Tucker's boyfriend was never considered a suspect in her disappearance, and her husband is now deceased. Her case remains unsolved.
