Very interesting post.Genuinely I feel the Police know a lot more about the case, are sharing very little with the family and that there is a huge sticking point keeping the Police quiet ( I have couple of possible reasons which I won't/can't talk about here just yet).
I just can't see the Police continuing to not do things/do them late/do them incompetently when the family have, and continue, to call them out publicly, IMO.
