I'm not sure I understand your post. But..The dog found the body? And what - went to the police?

No, it was the dog with Luke.. he wasn't side by side with the search party. It's accepted that he found the body - what he says leads him there will change from time to time.
But I can't ignore.
His obessesion with knife murders.
The fact that his own brother failed to give him an alibi - he lied about being home.
The two witnesses that saw him on that lane at the time of the murders.
The note he wrote on the knife.
That it was he who quickly discovered the body in poor conditions (and the attempts to twist this information after the trial has finished).
He had a good lawyer, hell a great lawyer. But his own family were a huge factor in him being convicted, as well as the witnesses that saw him on that lane.
Every 'appeal' has failed. In fact - there was an appeal that decided not to appeal on the evidence but to appeal ont he fact he should be let out (or at least re-tried) because he didn't have access to a lawyer or the first how ever many hours he was arrested. When you get THAT desperate then you know hope is lost.
I don't even think he has a lawyer now - isn't Sandra Lean in charge of his case?
Mitchell isn't going anywhere. Bamber has more of a chance than getting out than Mitchell ever does.
