So, they extended the offer of limited immunity to next Tuesday? I don't think it matters, but I guess LE is going to give her time to come up with an "accident theory".
Even if she intentionally killed little Caylee in some fit of anger, all we'll have either way is no story at all, or the made-up story that makes Caylee's death so not CA's fault that it may seem like Caylee is to blame. Bottom line: Best we can hope for is finding little Caylee's body. The truth is lost forever.
