Summary based on the NamUs case record (MP2698) and 4 other sources
Martin Marshall Daggett, a 68-year-old resident of Yucca Valley, California, disappeared under mysterious circumstances on February 6, 1997. That day, Daggett left his home intending to travel to Las Vegas, Nevada, where he had reportedly planned to stay at the Flamingo Hotel. He was never seen or heard from again. Daggett, who stood six feet tall, weighed approximately 170 pounds, had blue eyes, wore glasses, and was bald with some gray hair, was reported missing shortly after he failed to check in or contact family members.

In a chilling development, Daggett’s van was eventually located at the Flamingo Hotel in Las Vegas. The vehicle had been thoroughly cleaned out, with the only remaining item inside being a Purdue University jacket—raising further questions about who last had access to the vehicle and whether foul play may have occurred. There were no signs of struggle or immediate evidence to suggest what had happened to him, and none of Daggett’s personal belongings, such as identification, clothing, or luggage, were found in the van or nearby. This discovery has fueled speculation and deepened the mystery surrounding his disappearance.

Authorities from the San Bernardino County Sheriff's Department led the investigation, but over the years, the case has gone cold. Despite entries in national databases such as NamUs and efforts by advocacy groups like The Charley Project and the Doe Network, no substantial leads have emerged. These organizations continue to keep his profile visible in the hopes that someone will come forward with vital information.

Daggett’s case remains an enduring enigma in missing person investigations. His cleanly emptied van, abandoned far from home, continues to haunt investigators and his loved ones alike. Anyone with knowledge of his whereabouts or the events surrounding his disappearance is urged to contact law enforcement, as even the smallest tip could be the key to solving this decades-old case.
