Pond Searched for Missing Girl

North Carolina investigators says they've found a bone that might belong to a missing 10-year-old deaf girl. Zahra Baker also lost a leg to bone cancer. She was reported missing several weeks ago by her father. Meanwhile, her stepmother, Elisa Baker, faces charges for admitting that she wrote a phony ransom note. Searchers are now focused on a pond, which is being drained as police looked for more evidence.
