Ok I don;t have a timeline with me. However could it have been possible that Casey sent Caylee with Ricardo or Amy to PR when they went? Did Caylee accompany Casey to the airport? I find it very strange that Casey was buying these people tickets to PR, if she herself could not go due to her not having enough money to do so. Esp if she bought Amy a ticket to PR but then turned around and stole money from Amy. Did I understand it that Casey DID buy herslef a ticket to go to PR the same time that Ricardo and Amy were there? I have to wonder if Ricardo, Amy and Casey were not somehow in to a plan where they would help Casey move to PR to get away from her parents, and sent Caylee ahead with SOMEONE.
I think they need to start searching for Caylee in PR. That is IF she is still alive, which sadly I don;t think she is.
