Summary based on the NamUs case record (MP511) and 5 other sources
In the late afternoon of October 5, 1994, 38-year-old Barry Paul Duncan was seen driving away from South Mountain Park in Phoenix, Arizona. This would be the last time he was seen or heard from by his loved ones. Duncan, a white male with blond hair and blue eyes, was approximately 6 feet to 6 feet 2 inches tall and weighed between 180 and 190 pounds at the time of his disappearance. He had a mustache and a distinctive tattoo on his upper right arm of a large black and white wizard with blue eyes. He was also known to wear a single contact lens.

The days turned into weeks with no word from Duncan, amplifying the concern of his family and friends. A significant break in the case came on October 16, 1994, when his black 1979 Ford pickup truck was discovered abandoned on the Gila River Indian Reservation. The discovery of his vehicle without any sign of Duncan intensified the mystery surrounding his disappearance. The location where the truck was found, away from his last known location, added a troubling layer to the investigation. Authorities immediately suspected foul play in his disappearance.

The investigation into Barry Duncan's disappearance has remained open for years, yet answers have been elusive. The Phoenix Police Department has been handling the case, but the passage of time has not brought a resolution. Investigators have explored various leads and theories, but the circumstances of what happened after he drove away from South Mountain Park remain unknown. The lack of any substantial evidence or witnesses has made this a challenging case to solve. The official classification of his case as an endangered missing person highlights the serious concerns for his welfare from the outset. The overview of this case is one of a man who vanished, leaving behind only his abandoned vehicle and a family left to wonder what transpired on that October day.
