Why did they think it was all about George?
The most vulnerable because of the attempted suicide. It also would have that certain shock value that couldn’t be proven; but might be true(which I don’t believe). The only one that could have been half believable is the affair between George and the woman with two different names and that is only because people can act like dogs on occasion. I don’t believe that one either.
They didn’t feel he was forthcoming and because they couldn’t prove cause of death they seemed to suspect that he might have killed Caylee. It seems they completely overlooked all of the bizarre behavior by Casey. Baez threw enough dirt at George to make him a suspect in their minds.
