Diane Leslie Reeves was 23 when she disappeared from Ferndale, Washington. She was last seen at home on July 26, 1989, reportedly in a state of emotional distress. Her boyfriend reported her missing, though the interval between her last sighting and the report is unclear. At the time she was 5 feet 7 inches, about 160 pounds, with blonde hair and green eyes; she was reportedly wearing a gray Levi’s jacket, a gray sweatshirt and yellow sweatpants.

On September 2, 1989, Diane’s silver 1983 Plymouth Subaru was found abandoned at the end of a U.S. Forest Service road on Green Mountain in the Mt. Baker-Snoqualmie National Forest, east of Granite Falls in Snohomish County. The keys were on the front seat and her hat was found nearby. There were no signs of a struggle or violence at the scene. Search teams including volunteers, helicopters and bloodhounds searched the dense, steep terrain but did not find her. Diane had recently been diagnosed with cancer and had reportedly experienced episodes of confusion or amnesia, facts investigators have considered alongside the remote, difficult location where the car was recovered.

Did anyone see Diane in the Granite Falls area that summer or remember a car matching that description on Green Mountain road?
