I think Jeremy was in the dark as regards what happened and like some of us,is trying to fathom out a few anomalies that there are,,and piecing things together as best he can. Which is all you can do,because if you weren't there,then it remains to be all guesswork.
I'm sure after nearly 28 years of being locked up,that if he'd been the culprit,he'd have thrown the towel in. People now are so annoyed that he's been determined not to alter his plea. It must be getting on everyones nerves,,,,I'm glad to say.
