For the hey of it, I'll throw my 1st theory on here.
Could Casey have been foolish enough to think she could leave her child, say by the airport, alive...kinda just dump her there. Maybe the big trails around the park? I favor the park drop off. Then she tried to call her family and claim she was abducted? Calls went unanswered....
She may have thought Caylee would wander and find someone who would take Caylee to the police station? Casey could then claim she didn't know where Caylee was and that she left her with the Nanny there, act stunned when police returned Caylee home.
Casey let time go, had a good time but funds were running short w/o parents cc's that were cut off. Her parents are wanting to see Caylee. She returns and searches, finds a deceased Caylee. Her parents had started to threaten to turn her in for theft etc.
She tried to unload the stolen gas cans so that wasn't on her, she was caught by George.
Casey didn't have Caylee and started to panic. She leaves her cell phone somewhere and goes to get Caylee, so she's not again connected to a 'ping site' where she could claim she had met the nanny to drop Caylee.
She moves Caylee the 24th after having been to the family home, get George's work schedule yada--returns home to wrap Caylee up, uses computer. She talks to Jesse.
She then ditches the car because of the odor, and also her parents are threatening to report it stolen. Gave it up as a theory as it didn't piece together well.

Back at square one, but the timeline of Caylee missing and the flurry of calls on 6/16 leaves me with 1pm-3pm (flurry of calls) 7pm-ish Casey at TonE's. This makes it seem as if it wasn't an accident. I have a hard time with that theory, too.

The other theory is Casey was at the Anthony home late Sunday night 6/15, she leaves wee hours with Caylee to be at TonE's, leaves a sleeping Caylee in the trunk and the next morning, Caylee is deceased. This theory leaves George lying about the late morning of 16th. Which is me assuming facts and making the story fit my theory. So, hard time with that one too.
Sooo..I don't know what happened. *sigh*
