As much as I have tried to talk myself out of it, I do believe George has told a lie, a major one in this case.
A few people are puzzled as to how George could remember what Casey and Caylee were wearing the last morning he saw them leave the house. Well, it's easy, cause I believe George made up that story. There was no Casey and Caylee getting up, eating breakfast and going off to work with George carrying Caylee to the car.
I think there was a big fight, which turned physical, between Cindy and Casey Father's Day evening after Cindy returned from visiting her father and being with her mother. The fight I think was over Casey stealing again from Cindy's parents. This made Cindy furious at Casey mainly because I see Cindy as being very concerned about what others think of her as a mother.
I think Casey took Caylee and left the home after there was very hurtfull and threatening words between them that night. Possibly Casey with Caylee spent the night at Lee's place. As usual, Casey returned to the house once she knew George and Cindy had gone to work.
It was her calls to her parents where she didn't get a response that day that made her even more furious at them. She wanted to be with Tony. They had made a date for that evening and to spend the day together the following day. She needed a babysitter and was determined not to cancel.
That's when I think Caylee lost her life.
George's reason for lying about seeing Casey and Caylee leave that day was because he did not want officials to know about the terrible fight between Cindy and Casey. He did not want them to know Casey left the home in the state she was in.
This lie is something that both Cindy and Lee have had to cover George for. I really doubt I am wrong about this part of George's story of when he last saw Caylee.
