The bodies of two Georgia scuba divers were found more than 500 feet inside a treacherous spring cave, police said. Mark Anthony Granger, 19, and William Anthony Ridenour, 34, both of Kingsland, Ga., received their diving certifications Sunday and were on a dive with their instructor when they died, authorities said. Rescue divers found Granger's body Monday morning in 40 feet of water 500 feet inside the Royal Springs cave, police said. Ridenour's body, which Hall said was hard to find because of silt in the water, was later recovered about 50 feet farther in.
