This scenario sure would explain quite a bit, such as the overwhelming smell and why caylee's body can't be found. I definitely heard cindy say "george" on that 911 call, so something is surely amiss here.
I never really believed that casey willingly abandoned the car in fact I believe she was fairly desperate to get that car back and I can only imagine what she thought happened when she discovered it was gone.
I recall reading that Amy took KC to Target on the 30th to buy a gas can, but don't recall reading anything about what they did with that gas can after getting it??? Did Amy drive her to Amscot with gas and the car wasn't there?
I just read today that AL was the one who broke the lock off the shed with a crow bar on the 23rd to get the gas cans. He said KC insisted she pour the gas in the car herself and would only let him pass her the gas cans. He didn't smell anything on that day, but KC apparently didn't want him to get too close to pour the gas for some reason.
What did she do with the gas can on the 30th because I can't imagine at that time she would have had Amy drive her to Amscot to put gas in the car for fear Amy would have smelled the car which she said stunk by that time. She told Amy on the 27th that it was dead animal splattered on her car that caused the stink, so it must have been worse on the 30th.
