KC borrowed the shovel on the 18th of June according the the man she borrowed it from. I think on that date Caylee had already been dead a couple days, and was laid on the ground near the playhouse where the dogs hit. She laid there not bagged, IMO, because decomp fluids transferred to the ground. She may have been covered with the standbox lid.
For KC to have put Caylee in the pool to drown, or to hold her head under to drown her, doesn't seem as likely to me because I think it is too risky--neighbors might see or hear something.
If Caylee died in the home, she was put immediately in the car trunk, IMO. Unbagged, as evidenced by the stain on the carpet. But I still tend to think the child died in the car, either in the trunk or was placed immediately in the trunk. That she was in a fetal position seems to indicate the trunk--she might have curled herself into that position as she died. (These words do not flow easily from my keyboard)
Caylee was dead in that trunk at least a day and more likely two days, unbagged, IMO. Otherwise there would not be the staining, or the stain would not be as prounounced as it appears to be.
I think KC returned to the home with Caylee on the 18th, borrowed the shovel, then when that didn't work out she THEN bagged Caylee and put her in the trunk. She could have put the heart sticker on then but I think the duct tape was in place long before that, and was the cause of death. I think Caylee was disposed of not long after being bagged but that the bulk of the time she lay in the trunk she was unbagged.
That was painful to type.
I do not see accident at all. Often murders are staged to looks like accidents but I really cannot recall even one case where an accident was made to look like a murder. I might be a little more open to that idea if anyone can point me to even one such case.
