BOULDER CITY, Nev. - Xavier Fleuranceau, a 48-year-old Utah man, died of asphyxia while scuba diving in the Black Canyon area of Lake Mead, according to the Clark County Coroner's Office.
Fleuranceau was found floating face down in the water on Sept. 29. National Park Service Rangers and the Nevada Department of Wildlife started CPR but were unable to resuscitate him.
According to witnesses, Fleuranceau was a mixed gas dive instructor who was diving with a group at depths around 350 feet when he ran out of air. His dive partner shared a spare tank as the two began to ascend. At some point, Fleuranceau separated from the safety line and performed a free ascent without gas. The other divers ascended using normal decompression without incident.
