I was wondering if any of the POI had made any big purchases. Im not sure this can be determined by us sleuthers, just an idea I am throwing out there.
They do not seem to be flush with cash by the looks of them. The only reason I say this, and Im going to a deep, dark place here. William is a boy, the majority of the POI have been associated with female victims. Maybe the intention was to get both children, or to grab WT sis, but it makes me think that maybe William was abducted and sold. I am also wondering if this is why the police believed for a long time (and maybe even now, not sure) that William was still alive. Because he was no longer in the hands of the abductors because he was sold or handed of to someone else.
Of course this is all just a thought, this may have also been covered. I have no facts to back it up. But is anyone aware of a POI new house being a lot nicer than their last or a shiny new car or something like that.
Apologies if this is idea has been discussed at length already. Ignore me if so.
