The child went missing on January 22 while playing with friends near his grandmother39。s house in North Carolina. When the other children returned but Casey did not, the family searched the area for almost an hour before calling the police. Police formed a search team to look for the young boy in the nearby woods. But two days went by and — no Casey. Then on January 24, someone called the police saying he heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. He was in good health. Casey told the rescuers he had hung out with a black bear for two days, a bear he called his friend. The police officer Chip Hughes spoke with reporters from several news agencies.
