Arthur Brandes was 47 when he was last seen in Denver, Colorado, on September 13, 1996. Initially known to occasionally drop out of sight, his absence did not alarm family right away. Concern grew over the following weeks and months, and in November a relative reported seeing Arthur’s truck being driven by an unknown person. Police recovered the vehicle but found no clues inside about his whereabouts.

Arthur was described as a white male with brown hair and brown eyes, sporting a mustache. He had a noticeable limp, often used a cane, had a history of alcohol abuse and some unspecified health problems—details that could have made him vulnerable. The Denver Police Department has kept his missing persons file open but the trail went cold after the truck was found.

Does anyone who knew Arthur or who was in Denver in the fall of 1996 have information that could help explain what happened after September 13?
