All I know is I am now 100% certain ICA had Caylee's body in the backyard where the grass don't grow. Thanks JB and expert for solidifying that for me.
Warning LONG & GRAPHIC
That was kind of the missing link.
ICA calls everyone under the sun to watch Caylee (4-4:30 PM on the 16th) She then appears on the Blockbuster video with TL that evening and spends the night and the next morning with him, in bed, per TL...under oath.
At some point on the 17th she ends up back at her family home and decides she must borrow the neighbor's shovel.
IIRC, Cindy finds the side gate had been left open and the pool ladder was left attached to the pool. But was that the 16th or the 17th?
(Was Casey setting the scene to cover an accidental overnight suffocation in the trunk? Or did she take her home on the 16th, between all the calls and her trip to Blockbuster, lose her chit and kill Caylee at home?)
IIRC, three days (20th) later she and TL break into the shed and ICA steals the gas cans. Did the car already stink from the 12+ hours that Caylee lie in the trunk dying and then dead? Would it have already started to stink?
Or did the car only begin to stink after she moved the body from the backyard to the car, leaking some fluids even after she wrapped it so well, and then drove around looking for an opportunity to dump Caylee's little body?
Either Caylee died, accidentally through neglect (left overnight in the trunk) or she died at home between 4:30 and 6:30 PM on the 16th. Then it would appear that Casey temporarily hid her little body in the backyard (probably in the playhouse or sandbox) and gathered all the necessary things to wrap her up and transport her to the dump site. In the process of tilting her to get her in the trunk, some Adipocere may have leaked out of the bags and onto the tire cover. It is very possible that her body had not started decomposing in the trunk but wherever she hid her on the 16th or17th. (People watching the trial noted that ICA wore purple today (17th) not yesterday.)
