I have a hunch that they are going to claim that KC did give Caylee to someone for safekeeping while the drama played out at her house--only for obvious reasons they can no longer claim it was ZFG. Who they will claim it is I have no idea. That is the only way I see them getting around the 31 days and the partying.
I was thinking about this the other night because I was reading through the jailhouse letters again where ICA states she gave Caylee to the "real" Zenaida. It was as if she was saying okay, not that ZFG the one I told the cops about, but the real one. When I was reading this I was wondering how the defense team were going to say okay she was lying to LE, there was no nanny - because all the State have to do is bring up that letter where she is still saying there is a nanny or a Zenaida.
So your theory makes a lot of sense. There was a criminal defense attorney on tv saying you must be very careful if you are going to put yourself at the scene of a crime because you are asking a jury to believe you were there and it was an accident, but you didn't do anything to cause the death. This attorney said that this scenario is fraught with danger and no way would he advise a client to admit to putting themselves at the scene of the crime at the time of death, because a jury is just as likely to believe that you're lying. At the end of the interview he didn't believe that the defense would go down the road of accident theory.
I don't think they will either - the defense has to explain that jailhouse letter and I believe they will say that ICA gave Caylee to "someone" probably much like the Elizabeth Johnson case.
So defense theories they can't use...
1. Accident - ICA won't admit to that because she would still get serious jail time, can't put client at scene of crime at time of death
2. George did it - No one is going to believe this, there is no proof whatsoever to support this claim, nor can a case be made for reasonable doubt.
3. ZFG (LE statements) ex members of the defense team have already come out and said this is a lie - This Zenaida does not exist
4. Roy Kronk - again no one will believe this as this man was unknown to the family, had no access to Caylee and Caylee was in possession of her mother at last sighting - no discernible proof to back these allegations.
5. JGrund - once again, no access no proof
I think the mitigation experts/investigators poured over ICA's scribblings from jail and are using everything they can in there - and that is where all the mitigation excuses come from and the "REAL" Zenaida.
