I disagree. I think because those samples would relate to a different event, police would not have any reason to release that detail to the media. It is, however, highly relevant to the lunch and murders, because is part of a bigger backstory, and as such would form the brief of evidence.IMO had there been any pathology samples relating to Simon, we would have heard about them before now, and I believe that charges in that matter would have been laid earlier than today.
Let's see what the Crown puts forward as evidence for those charges.
