Donald Richard Cowan was a 40-year-old White male who was last seen on December 21, 1982, in Las Vegas, Nevada. According to law enforcement and missing persons records, Cowan left his home in the 6300 block of Katella and never returned. From that day forward, no confirmed sightings, communications, or verified traces of him have been publicly documented.
His disappearance was reported to the Las Vegas Metropolitan Police Department, and the case has remained an enduring missing persons investigation for more than four decades. At the time he vanished, Cowan was described as approximately 5 feet 10 inches tall and 170 pounds, with brown hair that was thinning in the front, hazel eyes, and a brown mustache. He also had distinctive scars on both sides of his abdomen.
The publicly available information surrounding Cowan’s disappearance is notably sparse. Investigators have stated only that he left his residence and never returned. Unlike many missing persons cases, few details have been released regarding his activities immediately before he vanished, where he may have been headed, or whether he was expected to meet anyone. The lack of information has made the case especially difficult to resolve. Over the years, Cowan’s file has remained active within missing persons databases and cold case listings maintained by law enforcement and national missing persons organizations. Despite the passage of time, authorities have continued to preserve the case record in hopes that new information could eventually emerge.
As investigators examined the circumstances of Cowan’s disappearance, attention eventually focused on David Dale Morgan, a former business associate of Cowan. According to information published by The Charley Project and derived from law enforcement sources, Morgan became a person of interest because authorities believed he may have been connected to multiple disappearances in the Las Vegas area. Cowan’s case has been discussed alongside the disappearances of Gabriel Vincent, Marie Morgan, and Diana Leone, all of whom vanished under separate circumstances spanning several decades. Although Morgan was at one point charged in connection with the murder of Gabriel Vincent, that prosecution was later dismissed after the death of a key witness, and no criminal charges were filed in connection with Cowan’s disappearance. Investigators nevertheless continued to regard Morgan as a prime suspect in Cowan’s case, though the disappearance remains officially unsolved.
The years that followed brought no publicly reported breakthrough. No vehicle was associated with the disappearance, no confirmed evidence explaining what happened to Cowan has been released, and no recovery has been announced. As decades passed, his case became one of the Las Vegas Metropolitan Police Department’s long-standing missing persons cold cases. For family members, friends, and investigators, the absence of answers has meant living with uncertainty about what occurred after he walked away from home on that December day in 1982.
Today, Donald Richard Cowan’s disappearance remains an unresolved mystery. The known facts are simple yet haunting: a 40-year-old man left his Las Vegas home on December 21, 1982, and was never seen again. While investigators later explored possible connections to a former business associate who was linked by authorities to other disappearances, no definitive resolution has been reached and no one has been charged in relation to Cowan’s case. The enduring overview of the case is that of a husband, family member, and community member who vanished without explanation, leaving behind decades of unanswered questions and an investigation that continues to seek the truth.Last Seen: Dec 21, 1982
