You know, the one thing that I think most points to a known person possibly involved is that odd Eric reply Snapchat series, supposedly from Aniah. It has never made sense to me that some criminal is going to stop and do that, while in the middle of kidnapping someone, KWIM? And it sounds like someone at least attempting to sound like Aniah.
P.S. It also seems just as odd that accomplices would do that, to "buy time," but I guess it's possible...it just doesn't make sense in the context of what was going down.
