It was on the first 911 call that CA was on hold but still talking to KC and didn't realize that she was being taped while she was being transferred to the aprioprate agency.
Cindy Anthony: My next thing will be child's thing and we'll have a court order to get her if thats what you wanna play. We'll do it and you'll never...
{Casey inaudibly talking}
Cindy Anthony: Well then you have...no I'm not giving you another day. I've given you a month.
And then the first week in July she had that post on her myspace about how Caylee was gone.
CA hadn't seen Caylee in a month. Casey always had some lie about why she couldn't. The July myspace references the same thing. CA thinks Casey is keeping Caylee from her on purpose. IMO, the myspace is an attempt to reach out to Casey and also garner sympathy from others (perhaps Casey's friends, who might lean on her to let CA see Caylee).
