I see the idea thrown around that maybe Zenaida F-G was in the country illegally, or had stolen someone's identity, and I thought about that, too- but then I keep going back to this...
even if that were the case, in the affidavit Casey said she worked with ZFG, had known her for four years. Let's say that she DID get that job illegally, with a fake id, and fake personal info- Universal Studios still would have had a record of the fake ZFG. They had no record whatsoever of that employee. That says to me that Casey made her up.
Also, the fact that Casey claimed that John Hopkins and Juliette Lewis (?) would be able to confirm the story of ZFG taking Casey. Not so.
Also, she claimed ZFG frequented those clubs Casey was at, and Casey claimed that is the reason she was there...looking for ZFG and her daughter. Well, wouldn't her circle of friends know this ZFG, if she also frequented those clubs?
Another thing is, I feel certain that LE has contacted Universal Studios to get a list of other co-workers who worked in the same department at the same time as Casey, and the supposed ZFG.
I think the ZFG thing is a total lie, and that Casey is just a habitual liar.
