That’s relevant to the HaB assault not MM (of which we know nothing ), matches numerous elements , black clad and masked , filmed , tied by their feet , same words used to scare HaB .
My deduction of photo or video evidence is the only possible piece of arguable evidence that makes the BKA 100% convinced MM is deceased and CB is the perpetrator. Anything less arguable and concrete would have resulted in charges years ago. It could well be these current charges in the trial were put forward to provide insight and background detail into the mindset of CB before and after May 3 2007 .
