I believe in post #251 of this thread there is a link.
From what I remember, they say that the man we now know as JM had been talked with and had nothing to do with with HG case, and even that police issued a statement to say so.
I remember, because I then went to the police departments website and could find no such statement. It is pretty much a blatant lie.
OK. I remember that too but the speculation was that they had basically exonerated WG and someone had gotten confused and reported it as JM had been exonerated instead.
