Summary based on the NamUs case record (MP14201) and 4 other sources
Douglas Harlan Selby, aged 37, was last seen on August 22, 1989, in Key Largo, Florida. He disappeared after leaving the Caribbean Club, a local establishment, while driving his 1980 Dodge pickup truck. His truck was later found abandoned outside the Twin Harbors Campground near mile marker 104, but Selby has not been seen or heard from since.

At the time of his disappearance, Selby worked as a plumber. He is described as a white male, standing between 6'0" and 6'2", with brown hair and brown eyes, and weighing about 190 pounds. Notably, he had distinguishing scars on his chest and back, the result of a past gunshot wound.

The circumstances of Selby’s disappearance have led authorities to suspect that he may have been taken against his will. However, very few details about the case have emerged over the years, leaving his fate a mystery. Despite ongoing efforts by the Monroe County Sheriff's Office and other agencies, his case remains unsolved, and investigators continue to seek any information that might shed light on what happened to him.
