The first call was made after Cindy picked up Casey from TonEs and Cindy may not have had much access to Casey's car. George drove it home while Cindy went searching for Casey . . . the comment about the smell was in the third 911 call, right?
All correct. But my point is that in the first call (to the wrong agency) Cindy clearly believes Caylee is alive and well because she's threatening to take custody. I forget the exact time...but it was about 8pm. The car was brought home about 3p (?)...so the coverup would have happened between 3 and 8 -- or are people suggesting the clean-up happened between 8 and 10p when police arrived? IMO -- No ways Cindy was covering up. And then the panic third 911 call seems so real to me. I believe G and C may have started covering up on the morning of the 16h, but not before.
