Flurries of phone calls usually happen after a big argument. If Caylee had an accident, why would Casey call four different people in a row. It sounds like there was a big fight and she was being hung up on or her calls weren't being answered on purpose.
This is what I'm thinking. Call, yell, hang up. Call, yell hang up. If the calls were answered, I'm guessing this is the situation.
I fear that it might be hard for LE to believe Cindy if she does admit to fighting with Casey...she's been maintaining for so long that "everything was fine" and keeping up appearances that they were all on good terms. If those calls were answered, and they spoke any amount of time, it could appear damning, as if the family knew...which I don't personally believe that they did.
What is weird to me, is if the ladder was always up, I guess we'd have to assume that Casey was swimming that day. If, by chance, Caylee DID wander into the pool, why would Casey not just call 911? And would the decomp smell appear so quickly? Would chlorine mask it?
I tend to believe that the body was hidden somewhere until the 24th, then in the car at some point from the 24th-27th. Because SOMEONE would have noticed the decomp smell from the 17-27th, it seems. I doubt she personally could have driven that long.
I also think she left the car, hoping it would be stolen...
Maybe (god forbid) she drowned Caylee, or otherwise, then tried to make it look like a drowning after she freaked?
