Summary based on the NamUs case record (MP10486) and 4 other sources
Douglas Stuart Mann, a 35-year-old man from Dunedin, Florida, disappeared on February 7, 1994. At the time of his disappearance, Mann was reported to have been struggling with depression, which has led to speculation that he may have left voluntarily. His parents believed he might have traveled to New York City, possibly becoming part of the homeless population there. Mann's case is classified as endangered missing, and although foul play is not explicitly suspected, the circumstances surrounding his disappearance remain unclear.

Physically, Mann is described as a Caucasian male, standing 6 feet tall and weighing around 145 pounds, with brown hair and brown eyes. Despite the passage of time, there have been no confirmed sightings or major leads, and his case remains unsolved. Investigators continue to seek information that could shed light on his whereabouts, but efforts have so far yielded little progress. Mann’s family and authorities hope that someone might come forward with helpful information.
