I went back to the beginning and re-read the arrest affidavit.
Casey claimed to have stayed at her ex-BF Ricardo's apartment since "the child went missing" (whatever date that's supposed to be now).
They also interviewed Amy, who is Ricardo's current GF and lives with him. She couldn't remember the last time she saw Caylee.
Sounds like Caylee was never at the apt with Casey, unless Amy is mistaken or lying. There are no statements by Ricardo in the affidavit (which is kind of odd, now I think about it).
So that leaves Jesse and his audio 'sighting' from the 24th, unless he is mistaken or lying.
It's interesting that a number of Casey's friends reached out to LE and "all claim she is a habitual liar". One of the calls was from Tony Lazzaro, the BF. Another was from Amy, the ripped-off friend. Another from Jesse, who is noted in the aff. as saying Casey is a habitual liar. Another was her BFF, Christine, who was surprised to find out Caylee was missing.
It's amazing that Casey had any friends at all.
