Jacques Gerard Damidaux, a 31-year-old engineer, was last seen in Miami, Florida, on October 14, 1988. That morning he told loved ones he was leaving town but did not say where he was going or whether anyone would accompany him. A friend later returned his vehicle and suggested he might have gone to the Bahamas, but no evidence has supported that theory.

His personal and professional life yielded few clues, and despite extensive searches and investigations the case remained unsolved. Damidaux was eventually declared legally dead because of the length of his disappearance, but the circumstances of what happened to him are still mysterious. The case is classified as endangered missing and investigators have considered foul play, though no concrete evidence has been found.
