Robert Marvin Elder, known to family as Bob, was 44 when he was last seen in Las Vegas on September 5, 1986. He had lunch that day with his niece and said he had been hired to drive two people to Kingman, Arizona, for a fee. After that meal he presumably went to meet the two passengers and start the trip — he was never seen again.

At the time he vanished he was described as a white male with graying hair and blue eyes, 5 feet 9 inches tall and about 160 pounds. He was last seen wearing a blue or turquoise shirt and dark gray pants. His yellow 1974 Ford Pinto, Oregon plate LLT148, also disappeared and has never been recovered. A missing persons report was filed with the Las Vegas Metropolitan Police Department on November 4, 1986; the two people he was said to be driving have never been identified.

The circumstances after he left his niece remain unexplained and there have been no significant public leads. Anyone who knew Robert, saw that Pinto, or has information about a trip from Las Vegas toward Kingman in early September 1986 is asked to come forward.
