John George Pappas, 54 and known as Johnnie Z, vanished from Las Vegas on the evening of August 18, 1976. He was last seen at his home near Robindale and Haven Street after telling his wife he was leaving to meet someone at a restaurant to discuss selling his boat. He drove off in his white two-door 1973 Ford Gran Torino with Nevada plates and was never seen again.

A few days later the Gran Torino turned up in a hotel parking lot with the keys reportedly still in the ignition. Pappas was described as a white male, 5 feet 10 inches, 185 pounds, with gray hair, brown eyes, eyeglasses, and a small growth on his left hip; he was wearing several pieces of gold jewelry including a necklace, a link bracelet, and a diamond pinky ring. Investigators early on said there was no indication he was alive; the case later went cold and remains an open missing person investigation.

Over the years theories have circulated linking his disappearance to organized crime and alleged ties to the Chicago Outfit, but those theories are unproven. Does anyone have information about Pappas, his white 1973 Ford Gran Torino, or the restaurant meeting he said he was going to?
