I think the 23rd is KEY to it all. Here is why. OBVIOUSLY there are some very disturbing inconsistencies in the testimony of her dad concerning the 24th and concerning the gas can theft. He claims that the last time he would have been in the building is the 22nd-Sunday. I am GUESSING that Cindy worked on the 23rd, a Monday, and so I am thinking that Casey ACTUALLY showed up at the house on that day and told her dad her "version" of what had happened to Caylee, and told him she had freaked out and had buried Caylee in the back yard and he assists her THAT very day or night in moving Caylee's body. He KNOWS that they(or he) cannot stop anywhere for gas, and so takes the gas cans from the building and then perhaps even LEAVES Casey at the house and digs Caylee up out of the yard and takes little Caylee away HIMSELF and buries her SOMEWHERE ELSE. He maybe even instructs her to make phone calls or get online, or something of that nature, so it appears as if she is at the house? or not... anyhow, when he returns, he does not tell Casey where he has put Caylee, so she can say in all honesty that she ABSOLUTELY does not know where her daughter is...
At this point, he has gotten all the details from Casey (at least her version MINUS the chloroform that she perhaps does NOT tell him about, but she may have) and she has told him that she came back on the 16th when they were gone and something happened to Caylee-she drowned, or fell or whatever, and she did not know what to do so she put her in the trunk of her car. She came back the next day or the next-seems to be a little question if it was the 17th or the 18th when the shovel was borrowed? and borrowed a shovel from the neighbor because the building was locked, on the guise of digging bamboo and buried Caylee in the yard. She knew she would eventually be discovered there because she could only dig a shallow grave, perhaps UNDER the playhouse or the sandbox where the digging would not have been noticed, and so she needed his help to put her someplace SAFE.
He comes up with a plan, part of THAT is to report the gas cans stolen and the shed "broken into"-in case any of the neighbors saw her there or anything was said he would have a REASON for her to have been there-stealing gas. Of course, he wipes ALL the prints off the shed lock so there will be no way to know WHO was in the building. He waits until the 24th and files the report with LE about the "break in"...
SOMETHING happened, something CHANGED about the way Cindy Anthony was ACTING from the time of the 911 calls-when George was NOT there, to the very next statement she made after he WAS there...and I think that something is that he had no choice but to tell her the truth and here we are today-with lie after lie after lie and circles and squares and every manner of shape that a lie is able to form...
Just a theory and if I am wrong, then I will apologize to George a thousand times for having thought it...
