David Robert Tait was 25 when he was last seen in Fort Walton Beach, Florida, on July 4, 1985. He was living in the Fort Walton Beach area and had been going through a separation from his wife when he disappeared.

Tait was described as between 5 feet 8 inches and 5 feet 9 inches tall, about 160 pounds, with dark blond to brown hair and green eyes. There were no known distinguishing marks or personal items reported, and the case has been hampered by a lack of dental records and DNA.

Despite extensive efforts by law enforcement and family, few clues emerged and no substantial leads have been reported; the circumstances of his disappearance remain unclear. If anyone knew David, had contact with him around July 1985, or has information that could help, please come forward.
