On 6/15 that was when the supposed fight happened, I think that Casey took off with Caylee and went to Tony's, gave Caylee something to sleep and locked her in the trunk.
Got up the next day, didn't bother to check on her untill it was to late and
A) Caylee, subcame to heat exhaustion.
Or B) Never woke up from whatever KC gave her.
Casey then maybe drove around with her in the trunk trying to figure out what to do.
Made the flurry of phone calls, Maybe in a moment of panic.
A)couldn't get a hold of anyone so gave up
Or B) Lost her nerve and decided to deal with it herself.
Went back to Tone's. With Caylee still in her trunk.
On the 18th when she knew no on would be home , came home and borrowed the shovel, burried Caylee.
Then Came back on the 24th , meaning to unburry Caylee and move her to the spot she is resting in today. ,but George was home so she pretended that she was just there to get something.
I cannot for the life of me figure out what date that she may have moved Caylee if she moved her herself.
If (and just spectulating here ) she had help, I believe they moved her on the 15th before the police were called.
If Caylee had been staying at TonE's before with Casey and had even slept with them in the same bed. Why wouldn't she just take her into TonE's with her, why lock her in the trunk? This what doesn't make since to me and this is why I think she killed her child on purpose, no accident.
