Summary based on the NamUs case record (MP22423) and 6 other sources
On a day in early autumn, Robert Marvin Elder, a 44-year-old man known to his loved ones as Bob, shared a meal with his niece in Las Vegas, Nevada. This lunch on September 5, 1986, would be the last time she, or anyone else in his family, would see him. During their conversation, Robert mentioned that he had been hired to drive two individuals to Kingman, Arizona, a city roughly 100 miles to the southeast. He was expecting to be paid for this trip. After lunch, he presumably went to meet these two people and begin the journey. He was never seen or heard from again.

At the time of his disappearance, Robert was described as a white male with graying hair and blue eyes, standing at 5 feet 9 inches tall and weighing approximately 160 pounds. The clothing he was last seen wearing consisted of a blue or turquoise shirt and dark gray pants. His vehicle, a yellow 1974 Ford Pinto with Oregon license plate number LLT148, also vanished and has never been recovered. The days turned into weeks, and with no word from Robert, concern within his family grew. A formal missing persons report was filed with the Las Vegas Metropolitan Police Department on November 4, 1986, nearly two months after he was last seen.

The circumstances surrounding Robert's disappearance remain shrouded in mystery, with very few details available to provide a clear picture of what might have happened after he parted ways with his niece. The two individuals he was reportedly driving to Arizona have never been identified, and there have been no significant leads or breaks in the case in the decades since he vanished. The Las Vegas Metropolitan Police Department continues to list him as a missing person, one of many cold cases that still await resolution. The passage of time has not diminished the hope for answers, but the lack of information has made the search for Robert a long and difficult one, leaving his family with unanswered questions about the fate of a man who seemingly disappeared without a trace.
