Summary based on the NamUs case record (MP38187) and 5 other sources
Robert Wayne Arnao, age 41, was last seen on December 17, 1991, in Key West, Florida. He left his residence without taking essential items, such as his medication or extra clothing, and drove away in a blue 1988 Oldsmobile Cutlass Ciera with dark tinted windows and the Florida license plate FZY76X. Arnao, who had a medical condition requiring medication, did not take his medicine with him, raising concerns for his well-being.

Arnao was described as 6'1" tall and weighing around 160 pounds, with brown hair and brown eyes. He also had a distinguishing scar from a gunshot wound on the center of his abdomen, and at the time of his disappearance, he had a mustache and long sideburns. Despite extensive investigations by authorities, no trace of Arnao or his vehicle has been found, and the circumstances of his disappearance remain unclear.

His case is classified as endangered missing, and the Monroe County Sheriff's Office continues to investigate, seeking any leads that might provide answers.
