Deborah Lois Dean, 23, vanished during a Greyhound bus trip home to Tucson in the spring of 1985. She called family from St. Louis to say she had made it that far, and that call was the last time anyone heard from her. Family believed she planned to continue toward Tulsa and Oklahoma City but she never arrived in Phoenix to be picked up.

Her single piece of luggage kept traveling without her and went as far as Los Angeles before being returned to her family. Her purse was found at a truck-stop cafe on the Greyhound route just outside St. Louis and, after going unclaimed, was mailed to her Tucson address in August 1985. Her prescription eyeglasses and contact lenses were missing; she needed them to see. Distinguishing features included thick brown hair, blue eyes, multiple ear piercings, a scar on the third finger of her right hand and a greenish tint to her teeth from childhood medication.

The Tucson and St. Louis police departments are handling the investigation. Are there any travelers, bus or truck-stop workers, or others who remember seeing Deborah on that route in 1985?
