Robert D. Thrasher was 29 when he left Spokane for Tacoma in early summer 1981 and was last heard from on June 23, 1981. He placed a phone call from Longview at 7:00 pm that evening; the next day, June 24, is recorded as his last contact. He was driving a tan 1977 Buick Riviera coupe with Kentucky license plate BDB 919, and neither he nor the car have ever been located.

Thrasher is described as a Caucasian male, 5 feet 7 inches, about 165 pounds, with blue eyes, brown hair, and a beard and mustache at the time; he had a scar on his knee. The Spokane County Sheriff’s Office opened an investigation on July 2, 1981, under case number 81-39035, and the case remains open with no public resolution.

What information do readers have about long-distance travelers on Washington highways in June 1981, or about sightings of a tan 1977 Buick Riviera with Kentucky plates that might help this investigation?
