They had done it several times before. But this time the exploration was fatal. Rescue divers entered the waters Sunday night searching for the two men but were unable to locate them. Their bodies were found only in the following morning. They found Peacock and Rittenmeyer “in close proximity to one another in 260 feet of water” in a “very dangerous and complex area of the cave system,” according authorities. Autopsies are being conducted to determine the cause of death. At least six others have died at Eagle’s Nest since 1981, most recently in 2013, when a father and son drowned during a Christmas Day excursion.
