Summary based on the NamUs case record (MP21155) and 3 other sources
In the autumn of 1985, a man named Mark Allen Weller, a 28-year-old resident of Kingman, Arizona, vanished, leaving behind a life and a family who loved him. On November 26, 1985, a day that would become etched in the memory of his loved ones, Mark made a phone call to his mother, a regular habit for the devoted son. During their conversation, he mentioned his plans to travel to San Francisco. This piece of information, seemingly innocuous at the time, would later become a crucial detail in the unfolding mystery of his disappearance. Mark was a man of routine and responsibility, and his failure to return home set off alarms for those who knew him best. At the time he went missing, he was described as a white male, standing six feet tall and weighing around 235 pounds, with brown hair and blue eyes. A possible scar on his left knee was also noted as a distinguishing feature.

The circumstances surrounding Mark's disappearance were puzzling and filled with contradictions. His girlfriend informed authorities that his suitcase was packed, suggesting an imminent departure. However, a suit that he had taken to be altered was never picked up from the menswear store. The owner of this store was reportedly the last person to have seen Mark. The clothes he was last seen wearing were a khaki-colored coat, jeans, a gray cotton shirt, and white tennis shoes. Adding another layer to the enigma, it was suggested that he might have been using the alias Mark Weller-Whitson. His 1979 Chevrolet convertible was found at his residence, ruling out the possibility that he had driven off in his own vehicle.

Decades have passed since Mark Weller was last seen, and his case remains an open and haunting cold case in Mohave County. The initial investigation by the Kingman Police Department yielded few clues, and the trail eventually went cold. Despite the passage of time, the hope of finding answers has not been extinguished. Details of his case have been entered into national databases for missing persons, ensuring that his information is accessible to law enforcement agencies across the country. The central mystery of the case revolves around the conflicting information of a packed suitcase and an uncollected suit, and the unanswered question of whether he ever made it to San Francisco. The persistent efforts to keep his memory alive serve as a testament to the enduring love of a family and a community's refusal to forget. The overview of this case is one of sudden and unexplained absence, leaving a void in the lives of those he left behind and a lingering question in the heart of a small Arizona city.
