Gary Palmer Moore was 26 when he vanished from Pasadena, Maryland. He was last seen on March 19, 1979; that day he called his mother from a friend’s house and said he was heading to the airport to pick up his girlfriend, but he never arrived and has not been heard from since.

Moore was 6 feet 1 inch, between 150 and 170 pounds, with brown hair, brown eyes and a mustache; no other distinguishing marks were reported. He was reportedly working as a drug courier at the time, and investigators have long suspected foul play, though no body has ever been recovered and the case remains unsolved.

Are there details about Gary’s movements on March 19, 1979, or anyone who remembers seeing him that day that could help investigators?
