Summary based on the NamUs case record (MP29902) and 12 other sources
John George Pappas, a 54-year-old man also known as Johnnie Z, disappeared from Las Vegas, Nevada, on the evening of August 18, 1976. He was last seen at his home in the vicinity of Robindale and Haven Street. Pappas informed his wife he was leaving to meet an individual at a local restaurant to discuss the sale of his boat. He departed in his white, two-door 1973 Ford Gran Torino with Nevada license plates. He was never seen or heard from again. At the time of his disappearance, Pappas was described as a white male with gray hair and brown eyes, standing at 5'10' and weighing 185 pounds. He wore eyeglasses and had a small growth on his left hip. He was also wearing several pieces of gold jewelry, including a necklace, a link bracelet, and a pinky ring with a diamond.

The circumstances surrounding John Pappas's disappearance have led to much speculation over the years. A few days after he was last seen, his Ford Gran Torino was discovered in the parking lot of a hotel. The keys were reportedly found still in the ignition. Despite this discovery, neither Pappas nor any further evidence of his whereabouts surfaced. In the initial stages of the investigation, law enforcement expressed that there was no indication he was still alive, and as time passed, the case grew cold. For years, there were few developments in the case, and Pappas's story faded from public attention amidst other local crime news.

The case of John Pappas is one that has endured for decades, leaving his family without answers. His disappearance has been linked in various theories to organized crime, with some suggesting he may have been a victim of foul play due to alleged connections with the Chicago Outfit. These theories remain unproven, and his case is still officially classified as a missing person investigation. The lack of concrete evidence and the passage of time have made resolving the case exceptionally difficult. The investigation into what happened to John Pappas on that August evening in 1976 remains open, a lingering mystery in the history of Las Vegas.
