A 911 call released Monday revealed new information about a man who was pulled from a 12-foot deep sinkhole in Durham after being trapped for hours. "No one is around and he is down in the hole and he's screaming," a 911 caller said. Redwood Volunteer Fire officials said the incident happened Sunday morning on a road near Falls Lake. The man was stuck in mud and cried for help. A nearby fisherman heard the man's calls for help and contacted authorities. "He was just uncontrollably shaking," said Chief Randy Clements. "He had obviously been very cold for a long period of time; was shaking just uncontrollably. He couldn't really verbalize other than he kept saying he was OK and was not hurt."
