I would struggle to believe that there is a single person in the immediate vicinity that hasn’t heard about it, I remember mikaeel Kular (reason I joined WS) and there was not one person not talking about it in Edinburgh, of course this was a child missing but still I feel even more so in a small village(s). BUT, it could jog someone’s memory who maybe only comes into the vicinity once a week say for whatever purpose. Everything is worth a try imo. I don’t really know how helpful reconstructions are but again worth a shot. I do wonder if they have got willow down there again to see if it veers them toward anything specific.
