Let me add this up, a silver ring with diamond trim marked crackjack or crackerjack with peanuts and popcorn nearby. Was it candy coated popcorn, peanuts and a prize perhaps? Must be the ill gotten gains from drug sales. You should turn this ring over to your local police immediately and tell them where it was located so they can stake out the area and look for this Carckjack character and nab him. It would make us all feel safer knowing you had done your part to help the community.
