I think casey tells the truth here, and that's when I decided the 16th was the last day Caylee was seen.
Q The end of May. And she last…you last saw her June the 9th?
A Ninth. A Monday
Q Hmm. Do you remember what y’all did on June the 8th ?
A It’s a Sunday
Q I can’t think of what I did, but.. Anything significant?
A I think I might’ve been at Tony’s. I think my mom took Caylee up to see her
parents in Mt. Dora.
She either took her up there that Sat or that Sunday.
edit to add: that statement does make you wonder if Casey really did go home the night of the 15th, as Cindy says. The time she gives for dropping Caylee at the Nanny's is between 9am and 1 pm, which is TonE's schedule and Casey usually left TonE's at 8:30 in the morning. I think when George saw Casey, Casey had come home, and it would have been between the 9am and 1pm time.
