I was wondering why she would take the body to that far corner of the yard to wrap it. Then I saw the very large umbrella in the screenshot of where Gerus alerted. Not the striped one that is shown opened, but the closed, very tall one. I believe the body was moved there to afford ICA some privacy while wrapping the body. I see many windows of neighbors that she would need to be shielded from.
I haven't tried to lay out a theory before, so don't hold me to this...I'm working through it as I type. (and I'm going only from the evidence presented thus far in court, so bear with me)
1). Cadaver dogs hit on the play area of the yard. If we believe the hit was accurate (and I do), then we have to concede that at some point in time, Caylee's deceased body was in that area of the yard.
2). Abundant testimony has been given to convince me that Caylee's decomposing body was found in the trunk of ICA's car. Not simply deceased, decomposing to the point where the smell was in the car LONG after her body had been removed. Now, that tells me that the body was either put into the car fairly fresh and was left there until the odor became unbearable (or too bad to hide), or it was put into the car at a more advanced decomp stage simply for transport to another location. If the later is true, where would the body have been stashed as it went from a fresh state to a reek state. Surely not in the backyard, unless it was buried back there. I would think that highly risky, and I would think that might be noticable to GA and CA. So, I'm inclined to believe the body was put into the car in a fairly fresh state and simply left there until the smell got so bad something else had to be done.
3). So back to the backyard hit by cadaver dogs. At some point, a dead child lay in that play area of the yard. Did the child drown and was she removed from the pool and then laid in the yard? Possible, I suppose. But I absolutely can not fathom the mother of a drowning victim going to all this trouble to hide an accidental drowning. NOR drive around with her dead daughter in the car until the reek is overwhelming. So no, I don't believe Caylee drown. What other reasons might a deceased child have been in that play area? You wouldn't drag the body out there unless you had a darned good reason too. Not with neighbors close by? The only "good reason" I can come up with is a place to hide the body until you can deal with it later. Perfect place in that area? Playhouse. And if you're carrying a dead child, you might have to lay it on the ground to open the door of the playhouse, of even move the playhouse if you can't fit inside.
4). Inside the vehicle we find a loose hair with a deathband on it. How did that end up loose in the trunk of the car if Caylee was double bagged back there? I don't think she was in the bag at this stage. I think she was put into the trunk, sans the bag, and later bagged in the trunk. No one to see, especially if this is done while vehicle is in garage.
So...here's my best guess:
Caylee died in the house, ICA was in a hurry to meet Tony. She carried Caylee to the back yard, put her in the playhouse and closed the door. She later came back, got the body, and laid it in the trunk of her car. Went about her business. The car began to sort of stink, so ICA triple bagged the body, but didn't know where to put the body other than back in her car. The smell then begins to permeate the entire vehicle. ICA is forced to deal with the situation. Thus, the body is dumped where it was later found.
That's the best I can come up with.
ETA: I do absolutely believe that ICA has a "deal with it later" attitude about life in general. Make a mess now, worry about the clean up later. Tell a lie now, worry about covering your butt later. So, I can absolutely see her not letting the fact that there is a dead body in the car cause her any worry, or stop her good times, until she is forced to deal with it. JMO
