John Warren Deetz, a 38-year-old truck driver from Fulton, Illinois, vanished from Spokane Valley, Washington, after a December 30, 1988 delivery to West Coast Grocery Company. He made two phone calls from the Broadway Truck Stop—one to his employer and one to his wife, saying he’d be home soon. His empty trailer was left at the truck stop, but his brand-new tractor-trailer, valued at about $100,000, and Deetz himself were gone.

Less than two years later a man named Ralph Howard Benson was seen driving Deetz’s truck after it had been repainted. Authorities recovered the stolen tractor on property linked to Benson in the Los Angeles area and found a 1988 license plate from Deetz’s rig, appearing new, during a search of Benson’s Washington home. Benson was described as a long-haul trucker who ran a chop shop and was treated as a person of interest, though he was never charged in Deetz’s disappearance. Benson later died in prison in September 2004. Deetz was legally declared dead but his body has never been found and foul play is strongly suspected.

Are there former truckstop workers, fellow drivers, or others who remember Deetz’s route, the Broadway Truck Stop on December 30, 1988, or anyone who saw that rig after it left Spokane Valley?
