Been thinking about this all night and day to understand if it might be a plausible theory: Could someone, like an illegal immigrant, have taken Zenaida's identity in order to hide in the U.S., WAS babysitting Caylee, and Caylee died while in the care of this person? Then I try to further extend this to: Casey either: a) found the body of Caylee that had been placed in the car by this person, or b) Casey found out that Caylee had died and because she was in fear of herself being killed by (i.e. gang members ) did not tell and was forced to dispose of her own daughter's body? OK. Then I think, Casey seemed unaffected by the events, so this couldn't have happened. What do you all think?
