This is, again, dead on w/ my thoughts. It is also in the police report that George approached the investigating officer very early on w/ concerns that Casey was not being forthcoming about what she knew. Both of these actions lead me to believe that both Cindy and George suspected Casey of foul play immediately.
I wonder, however, if Casey confessed to her parents and once they realized they would not be getting Caylee back they made the reluctant decision to try and protect Casey from prosecution. Either that or they initially hoped Casey had just somehow injured Caylee but--w/ the passage of time--have realized the inevitable and, again, now just want to protect Casey.
I would consider the possibility that they are making public statements in support of Casey in order to keep her trust to eventually influence her toward making a full confession but it does not fit w/ washing the pants and the conflicting stories about the gas cans. JMO. What are your thoughts on this, BlondieTx?
