I am so hung up on wanting to know how the child's mother got the name of Ms. Gonzalez. I am thinking she must have overheard the conversation that took place in the office. Or she had someone run the womans tag number.
This is where I'm curious about the former LE tied boyfriends.
Might one of them, whether this was an accident or intentional, and Casey (or someone) concocted the kidnapping story, then decided the best thing to do was pin it on someone who'd had her identity stolen recently?
I suspect, then, they thought doubt would be cast on the person who stole ZG's identity (afterall, they're already a criminal, etc.) and it would jumble the whole scenario, when instead, the ZG identity thing has been all but overlooked (publically, at least...heck, most haven't even mentioned it).
I think they expected LE to assume it was the same person who stole ZG's identity, or someone who was transferred information from the theft (as it's typically a chain thing) and Casey would escape a lot of the glare. Set-up the car with the purse it in, make it look like some other theft and somehow Casey escapes...only things never played out right, no one caught on early enough and so Casey never managed to "be missing" as well, etc.
I do NOT think it's a fluke she had ZG's info and that she'd been at the apartments, etc., and I think she was given that info from someone who had access to it somewhere, and my best guess is that points to someone tied to LE...
Which could expain her not trusting local LE...if she'd been given the info from one who had been among them, of course they'd not believe that part of the story. They'd believe their former LE person over her.
