STATE COLLEGE, Pennsylvania (AP) -- Lost for two days in a seven-mile-long cave in West Virginia, five friends were bruised, shivering and had run out of food and water. Three prayed for help, then heard a faint voice.
"I collapsed and started crying," said Heidi McWilliams, 20. "I thought we were hearing things."
McWilliams and her fellow explorers in the 718-foot-deep Mingo-Simmons cave, 130 miles east of Charleston, were treated for minor injuries and returned Tuesday to their homes in central Pennsylvania, a day after their rescue.
