Try this one out:
Where are GP's getting all this money? They are obviously not working and yet George says today he's got a full tank of gas to just "drive around". Mortgage, car notes, elec. water, internet, - many many bills associated with them. Impound lot to get car out - has to have been in the hundreds alone. So - maybe all 3 decided to "sell" Caylee - or at least ACT like they were. When the deal gets ready to go down - they get the money and kill the "child broker". Put the body in Casey's trunk to dispose of - any of them could have done the disposing - but probably George. But Casey - spoiled brat that she is - she "takes" off with Caylee. Of course child broker has other "eyes". Very first time Casey turns her back - BAM - Caylee is gone. Casey is too embarrassed to tell GP's - she goes "on the run'" - hiding out - making excuses for why the GP's can't talk to Caylee. Her car stinks - so she abandons it - hoping it to be stolen - instead gets returned home. The rest is history as we know it now.
