I'm taking what Tony says at face value and under the assumption he is being straight here. It would go some way to explain things the family have said changing so often if they haven't had info shared or even been given misinformation.
Either way we can assume that neither 'running man' or 'lurker' have been positively identified and/or approached. Since 'lurker' is of the greatest interest to identify and speak to and 'running man' is the only possible individual we know of that may be able to assist in identifying who he is it's a waiting game to see if anything comes out of these 2 paths. All quiet on the fbook page from the family though and no update as yet as to what the latest from the police investigation is as Nicola indicated Tony would do at some point in her post on Sunday evening.
