I'm like you. I don't buy the motive that Casey didn't get along with her mom or, that she just wanted to be unburdened by Caylee. It would have been so much easier for Casey to just walk away from Cindy and Caylee if that was the case.
I am one of those people that just can't take things at face value. I look for other possibilities. In fact, I probably go to far, but until I get concrete evidence of something, I can't let go of other possibilities.
For example, when I served on a jury for a domestic abuse case, I just couldn't accept the state's position that the defendant just decided to stab his brother-in-law. In made no sense to me. Upon examining the evidence during deliberation, I discovered, in the medical records of the victim, that the stab wound was only a half inch deep and at an odd angle. That made no sense if someone was really trying to hurt someone. In the end, I presented my position on what had actually happened. I concluded that the victim actually ran into the knife the defendant was holding (he had been peeling an apple for his daughter) at the time the victim jumped on him. The defense did not explore this as a possible option. The other jurors thought it made sense and we found the defendant not guilty.
So, I take things a bit further than most. Of course, I could be totally off base, but I can't help but wonder. What were both Casey and George doing when Caylee was supposed to have drown that morning? What could be the reason that they could not just admit that they weren't paying attention and she got into the pool? What could be so terrible that they were afraid to call 911 to report the drowning? What terrible secret could come out? Could there be more to the relationship of George and Casey? Casey has hinted at abuse. Was there really abuse? Was it consensual...if it happened at all?
Of course, this is totally off the wall. And, I will admit that I don't care for George Anthony. Maybe, I am just twisted and need to write crime novels.
