PrincessRose-I think your theory would be a good way to explain why KC didn't show any sadness those days. However, if they are completely certain and have solid proof that this "stalker" killed Caylee, wouldn't they have them arrested or show this proof to LE instead of letting this person be out and about, able to do this to other people while innocent KC sits behind bars until this goes to trial (which could be 1-2 years)?
There are several ways this could be explained - I've actually come up with about 10 different possibilities that would work and be very believable, but I don't want to post them on an open board. In general, it would have to be some complicating factor that would either make the stalker incredibly difficult to find or make LE incredulous to the point that they would be unwilling to arrest the person without absolute proof. As we have seen LE has really been focused on Casey and only Casey from the begining. They are utterly convinced of Casey's guilt. But the case remains entirely circumstantial at this point.
And if this person was jealous of KC's relationship with TL why would they be willing to take Caylee from her for a month so KC could live with TL?
In this theory the stalker told Casey they would take Caylee for a month, but really planned to kill Caylee from the very begining. Casey had no idea this person was jealous and plotting revenge. The person always acted like her friend. The stalker was merely taking advantage of the situation of Casey's fight with her mom and Casey and Caylee being out of the Anthony house in order to get Caylee away from Casey. The stalker may have even lied to Casey about taking Caylee on a trip. Basically, Casey thought she was entrusting her child to a friend. But the friend was anything but a friend.
Add to that the chloroform searches on the family's computer and traces in the trunk,
Could be Casey saw the "Win her with chloroform" pic on Ricardo's MySpace and looked chloroform up because she didn't know what it was. Maybe they were experimenting with the chloroform for other reasons or he asked her to make some for him and offered to pay for it - it's really not hard to make, especially if you have pool chemicals and household cleaners and such and Casey did need money. What I'm saying is there could be a more innocent explanation for this. Also if the stalker had access to the Anthony house (Casey said she gave Zanny a key), this person may have done the suspicious searches logged on as Casey. It is possible that this person really was watching Caylee for Casey from time to time and doing so at the Anthony house while everyone was out. Casey may have given this person her password so they could use the computer while there. This person may have been planning this for a long, long time. Maybe the stalker was planning on using chloroform on Casey as well.
KC smiling and laughing in court 2 months after her daughter's body was found,
I have known numerous people who lost young children (in several cases to cancer, in another to pneumonia, in another case, 2 infants (part of a group of triplets) who died of Strep A within a week of their birth) and most of these parents were not crying day after day for months on end. They dealt with the grief the first week or month, came to terms with it and moved on because there was nothing else they could do. They miss their children who are deceased, but have moved forward with their lives in the belief that they will be reunited someday. The one couple who didn't move on started over eating and now, many years later, weigh over 300 pounds each. Grief is different for different people. I think it is unrealistic to expect any bereaved mother to be crying and somber for months on end. Also, remember Casey is mostly sitting alone in a jail cell day after day. It must have been a relief for her to be out in a situation where she could talk to someone albeit briefly and even at court. Casey had already had 2 months to come to terms with the fact that Caylee was dead. And I do think that Baez is leading Casey to believe that she will be exonerated. Casey probably looks forward to seeing him because he gives her hope.
the fact that she wasn't buying anything for Caylee at Target, not trying to make any contact with this person to check on Caylee,
I think they will say this is because she believed Caylee was being taken care of so there was no reason to contact them. Or they may say the person who had Caylee WAS calling Casey, possibly using one of her friend's phone numbers. I'm sure you are aware that you can cloak your outbound calls so they seem to come from another phone number. As to buying stuff for Caylee - I think they will say the "friend" promised to provide everything because he/she knew Casey had little money.
her total lack of concern that first phone call to her house from prison,
Because Casey didn't understand how much trouble she was in and really thought Caylee was fine and this was all an overreaction on Cindy's part.
and the fact that KC has a known history of lying to impress people (therefore why wouldn't she lie and say she has an obsessed stalker as an excuse to cover her butt)
She was lying to police to protect her "friend." At the time she didn't know this person had killed Caylee or how serious the situation was. She also had no understanding of the fact that she was in a situation where her parents couldn't bail her out.
and I don't really think that defense would fly. Also, if she switched her story to this wouldn't that require her to take the stand?
No. Not if the defense is able to out this story in another way.
If I were the defense I would't attempt even trying this strategy just to keep her as far away from that stand as possible!
