Following on from the above. Let's just, for the sake of discussion, accept that the marks to Nevills back were caused by the barrel of the Anschutz 525 (the official murder weapon) heated up in some manner, without the sound moderator attached.
In isolation of any other theories, what do you think that would indicate? :
Before death - torture? (although anyone thinking of torture would - imo - choose areas of the body where more pain would be inflicted)
After death - checking for signs off life? (although a battering and 8 bullets incl 4 shots into the brain would surely have convinced the killer that he was dead!).
Is there any significance that can be drawn from the positioning of the marks (i.e. three small circular marks close together in a row down the middle, but towards the top, of Nevill back)??
Has it been confirmed that the three marks were made independently of each other, as opposed to say a three pronged instrument that could have made all three marks a the same time?
