Ashley Mauldin, 28, disappeared on July 10, 2006, during a recreational scuba dive 14 miles offshore of New Port Richey, Florida. After a 40-minute dive she never resurfaced.

The U.S. Coast Guard conducted extensive searches over a wide area of the Gulf but found no sign of Mauldin or her gear. The Coast Guard initially called it a diving accident, but Mauldin’s mother disputed that assessment, questioned the husband and the dive shop that sold the equipment because Ashley was not certified, and considered legal action. The FBI also became involved and foul play has been suggested, though no definitive evidence has been reported.

Her disappearance remains unsolved and she is still classified as a missing person.
