Summary based on the NamUs case record (MP41821) and 8 other sources
Donald Allen Warren was a 51-year-old man who seemingly vanished sometime in 1980. At the time of his disappearance, he was described as being a white male, standing between 5'4' and 5'5' tall, and weighing between 120 and 150 pounds. He had brown hair and hazel eyes. The circumstances surrounding his last known whereabouts are somewhat vague, with reports indicating he was last seen at a casino in either California or Nevada. For a long time, his family was left with very few answers, a painful ambiguity that stretched into years and then decades. The lack of concrete information made the search for him incredibly difficult, a journey through a maze of uncertainty with no clear path forward.

Years of tireless effort by his family eventually unearthed a significant clue that provided a more specific location to focus their search. Their research traced him to the town of Pahrump, in Nye County, Nevada. This connection was solidified by the discovery of a Nevada driver's license that had been issued to him, linking him directly to that area. Despite this breakthrough, the trail went cold from there. No one has reported seeing or hearing from Donald Warren since that time. His disappearance left a void in the lives of his loved ones, a persistent question mark that has endured through the passing of time. The hope of finding answers, of understanding what happened to him, has been a long and arduous road for his family.

The investigation into Donald Warren's disappearance is being handled by the Nevada Department of Public Safety. DNA from his son has been submitted and is on file, a modern tool that provides a glimmer of hope for a future identification. The case remains a quiet but active search for a man who has been missing for over four decades. His family continues to seek answers, hoping that one day they will learn the truth about what happened to Donald. The details are sparse, a collection of fragmented facts that have been pieced together over many years. It is a story of a man who was last seen in a place of transience and chance, a casino, before his life took an unknown turn, leaving behind only questions and a family that has never given up hope of finding him.
