I think Caylee was killed, not by accident, on the night/morning of June 15/16. Placed in trunk in the first bag. After two days, fluids leaked from the bag and one the trunk carpet. Casey drives to her parents, backs into garage to clean the mess. She puts poor caylee in the backyard to put her in another bag and duct tapes it shut. She cleans the carpet from the trunk. I'm not sure if the carpet piece is removable but I envision her taking it out and hosing it off in the grass. She uses the shpvel for something, possibly to lift Caylee from the trunk and to the grass. Casey seems too prissy to get too close to a dead body.

This all would explain the hits in the backyard. She puts Caylee back in the trunk after cleaning and putting the second bag on and doesn't wait much longer after this to dump her body in the woods.
Spotted Cat, I think you are very close on this. The only thing is that I don't see KC removing Klee from the trunk when it would be much easier to accomplish her task from the garage (cleaning, double bag, etc.)
I'm thinking it happened the afternoon of the 16th, by whatever means, possibly drowning with duct tape applied for obvious reasons. My hunch is that originally she was going to claim some horrible accident and get CA or GA to come post haste. When she couldn't get them, she had to abandon that theory and put the body in a bag in the trunk.
Then, couple of days later, as you suggest, leakage, odor or both begin to take place and the second bag, cleaning takes place when she backs into the garage and borrows the shovel.
I've been wondering if cadaver dogs can detect scent of a very new death and found the below -- suggesting that Klee could have been placed on the ground immediately after death, and the dogs could have still detected it.

Carpet squares were used as an odor transporting media after they had been contaminated with the scent of two recently deceased bodies (bodies are all less than 3 hours old). The contamination occurred for 2 min as well as 10 min without any direct contact between the carpet and the corpse. Comparative searches by the dogs were performed over a time period of 65 days (10 min contamination) and 35 days (2 min contamination).
The results of this study indicate that the well-trained cadaver dog is an outstanding tool for crime scene investigation displaying excellent sensitivity (75-100), specificity (91-100), and having a positive predictive value (90-100), negative predictive value (90-100) as well as accuracy (92-100).
Now this is gross, and I apologize, but apparently a body encased in a bag, say, can actually burst from the gaseous build-up of decomp.
Consequently, escaping gases from inside the body often create a uniquely repulsive odor even before any external signs of decomposition are present. Moving the body to examine it or to remove it from a scene only increases the amount of the gas and smell
Another snip, different article:
A simple test with a dead dog proved this idea (plastic bag) impractical: gas pressure caused the bag to burst.
So, although KC thought her second attempt would work, it probably only made the situation worse, and a few days later -- perhaps when she called Tony from Chikasaw Road, she had abandoned Caylee where she was later found. Later she had to abandon the car as well at Amscott.
The following is a snip from another site referencing his testimony:
http://www.docstoc.com/docs/2810979/Casey-Anthony-Documents-Released-Nov-26-001 (page 46)
He talks about the first time Casey ran out of gas, JUNE 23RD!!! He came to help her. Interestingly, he said when he arrived she was walking south on Chickasaw Trail. Now, if you look at a map of the area
thats not too far from home!

So he drives her to the Anthony home, makes HIM cut the lock on the shed and grab the gas cans, only to insist that SHE puts the gas into the car when they get back to it.
Sorry this is so long-winded, but I think we're getting close to the truth. Poor little Klee! It's really unfathomable.
