Well surely if she was really moving to a new job, wouldn’t she have to provide her Ss number to her employer? (As well as her full legal name.) Wouldn’t that be traceable somehow? Or was the “moving across the state for a new job” just a ruse to get the teenage witness away so they didn’t know where she was going?
I don’t get the impression she would intentionally hurt ND. But she already is hurting him by hiding him - this a child that will miss his mother, a child not in school, a child possibly not playing outside or in parks for her fear of being seen, a child at risk of medical neglect. He needs to he found and soon.
