Has anyone put forward the idea that maybe KC hit Caylee with the car? AH said Casey said she had found an animal "plastered" to the frame of her car.
if it was somewhere else i haven't seen it and i think it is a great theory.
she would have hit her with the car on an impulse of anger, panicked, put her in the trunk, tried to bury her or freeze her (remember when Casey took the frozen foods over to Tony's -- the frozen chicken and freezer pops? maybe she was emptying out a freezer..) then eventually drove her to ??? to dispose of the body (which is why she needed the extra gas in the cans). and maybe she had a helper who was extorting $$ from her.
