What I don't get about the father is more about CA and GA. They told investigators that they had paperwork from their lawyer giving them custody of Caylee in the event that something happened to Casey. They said that the papers were at home and they would get them. Then the next thing that we hear is that the investigators went to the lawyer and he never drew up any such papers. (I guess the As couldn't be bothered to actually bring in their paperwork)
Why would you lie about something like that to investigators? Did they not know that LE could ask for the paperwork from the lawyer or even subpeona the As to hand it over.
I just don't get these people. If you are going to lie, at least lie about something that they can't get proof of without jumping through a million hoops.
