The minute I heard GA's story about the 16th, I thought he was lying. It was the way he said it, his expression and the fact that he tried to say he was watching the "news", then got corrected by CA "it was BEFORE you went to work", and it became a cooking show. Exactly at 12:50pm.
I also remember CA saying she tucked Caylee in, so "at least, I know where she was that night" as if she wasn't sure about KC. Then she said she tucked them both in, so maybe KC was in bed with Caylee, getting her to go to sleep. But the 7am phone call from the house to KC's phone tells me someone was looking for KC and it wasn't KC looking for her phone - she was on it until about 3:00am. GA said he gets up about 8am, CA is already at work by then. So, CA called KC, IMHO - probably trying to find her to get her to come home from where ever.
No mention of Caylee waking, wet pull-ups, breakfast, cartoons, playing, lunch, interaction with Grandpa, running around the house - nothing. Until 12:50pm. And it was a normal day. Right. If anything, I think GA saw them leaving at 12:50am, while watching local news recaps after work. But, to CA the 16th is the 16th so a few hours difference is no big deal. A little lie. GA almost told the truth, but CA stopped him.
No mention by CA that KC's car was in the driveway or parked in the street. Yet.
