Just going back to the burns were they definitely burns as opposed to scorch marks?
Myster, re the OP case and the images you brought up can you remind me please what was being suggested?
- hot casings?
- scorch marks from the skin being caught by force?
I remember as a child swinging from things and getting marks on my hands which were referred to as burns but these were obviously not from a direct heat source.
The prosecution thought they were burn marks caused by a
hot bullet which missed, but then bounced off the tiled wall behind Reeva as she was facing the toilet door and landed somewhere on her back.
The defence said they were bruises caused when she fell back onto a wooden magazine rack which Pistorius stored in the toilet.
Two amateur sleuths recently decided they were bruises inflicted by the end of a cricket back before she was intentionally shot.
Regarding Nevill's back, I had the idea they might be burns from a single red-hot casing which ricocheted off the wall where the AGA was, or off the mantleshelf, got trapped underneath his pyjama top for a second or two to create the largest burn, then skipped down a bit further to make the smaller ones. The problem is... the size of the largest circle-shaped burn at around 10mm+ dia, whereas the flange end of the casing is only 7mm dia, although a burn might spread out depending on how long it's in contact with the skin.
Or they might have been done during the day, say if they were burning rubbish outside and a stray spark flew out and landed on his nape. The farm near to where I live are always having wood fires in fine weather, the last one only a couple of days ago.
I don't think they're friction burns in that unusual position.
