Are we to just discount the testimony of the ex-boyfriend that he heard Caylee during a phone call to Casey on the 24th? He states that he is 100% sure it was her.
What keeps nagging at me is if we believe him then there has to be a babysitter involved. Nobody claims to have seen Caylee with Casey between June 15th and July 15th. If we believe the ex-boyfriend then there had to be a sitter for Caylee because she wasn't with Casey during that time (according to friends of hers). And if we don't believe him, why would he say he is 100% sure that he heard her? If he's not lying then Caylee has been with a sitter from July 15th to at least the 24th or Casey played some kind of video or tape of Casey to fool him.
Why necessarily would there have to be a babysitter involved? It would only mean that Caylee was alive as of the 24th of June...she might very well have died that day becuase the same day or next day is when the gas gans were stolen...
