No expert evidence exists as to exactly how JB supposedly committed these crimes based on the physical evidence.
People will say JB bust into the bedroom and shot NB and June. They overlook facts like the gsw's NB sustained to his face were inflicted when the barrel was within inches of his face and the trajectories were around 10 to 12 degrees below the horizontal. The gsw's NB sustained to his rear were fired when the barrel was about 2 feet away from the body. The rifle is 48" in length. The pathologist said the wound NB sustained to his shoulder was fired from above. NB was 6'4", JB 6'0" and SC 5'7". How did NB receive this gsw in the bedroom? Even if you put JB/SC on top of the wardrobe I doubt you could get the downward trajectory that correlates with the wound track. You certainly wouldn't get it by them standing on the bed or chair.
Nevill wasn’t shot in the bedroom — he was shot on the landing. Whatever are you talking about? You’ve even admitted yourself that Nevill wasn’t shot in the bedroom: not one spot of his blood was found there, and all the casings where he was shot upstairs were found on the landing and stairs.
It’s blatantly obvious, as I explained in my previous post, that after Jeremy crept in and aimed bullets to his parents’ sleeping heads — in which it was dark too — he only managed to hit June’s head. Nevill would have then jumped up immediately and Jeremy needed to back away from the door onto the landing, otherwise he’d not have been able to shoot Nevill — as you say, the rifle was 4ft in length, without the silencer, bringing it to possibly 5ft. Jeremy needed distance to shoot Nevill, hence why he stood back on the landing and as Nevill rushed out the bedroom door that’s when Jeremy shot him him twice in the face.
Nevill tried to get downstairs to call 999 or/and arm himself, and Jeremy then shot Nevill in his arm/shoulder — and Jeremy would have been above Nevill as he did so.
The reason Jeremy poleaxed Nevill in the kitchen with the rifle, was that he’d run out of bullets.
I don’t see what you can’t comprehend about that?
I also suspect that after Jeremy beat Nevill to a pulp and rendered him unconscious, he deliberately wedged his floppy body on that upturned chair, folded him over and shoved his face in the coal scuttle out of sadistic fury, and then after reloading shot the final bullets into his head whilst he was in that grotesque position.
