John Smith Jr., 31, vanished from Las Vegas in November 1972 after being seen by a friend on November 13 reportedly heading to meet an individual known only as Rick. Two days later a missing persons report was filed with the Las Vegas Metropolitan Police Department. A few days after the disappearance the same friend received an anonymous phone call stating that Smith was dead; no body was ever found.

At the time he went missing Smith was described as a white male, brown hair, brown eyes, 5 feet 10 inches, about 160 pounds. He was wearing a black leather jacket, dark blue flared pants, a dark blue hat, black shoes, a watch and two yellow gold rings. He used several aliases, including John Conrad, John Gentry, Johnny Jentry, Johnny Smith and Junior Smith, which complicated identification and the investigation.

The case remains unsolved with no confirmed discovery of his remains and no public resolution. Did anyone in Las Vegas in 1972 know John Smith Jr. or the person called Rick and have information that could help explain what happened?
