" >> a man had shannon. he said she was fine and healthy. and before the caller hung up he told the operator his plans. >> when i'm done with her, basically, i will release her. what you'll find where i'm at right now is an article that belongs to her. and so he hung up and got off the phone. following that, the fbi did immediately trace the call. we got the call from emory. we traced it back to a phone booth. >> a phone booth outside the city. and just as the caller promised, there was something there. >> underneath the phone booth -- had fallen to the ground -- was a little cloth bag. and inside the cloth bag was a ring. >> a ring. yvonne recognized it right away.
