For the first two mouth/jaw shots, Nevill was lying prone in bed with head raised and facing the shooter who was obviously in a higher position at the foot end. No blood on the bed clothes as it was too early to start flowing enough, when he realised what was happening and had to get up sharpish.
For the other two shots, if he was sat on the bed about to get out, the first bullet hitting his left elbow which caused the arm to jump upwards leaving the shoulder in position for an almost vertical second shot (Samson's patented arm-jerk reflex theory). Or he might have been holding his left hand up to staunch the mouth wounds which would bring his arm up to a similar position.
NB was 6' 4". A standard double bed is 6'3" long and a queen and king 6'6" long. I think we can assume the bed in the master bedroom at WHF was queen or king. The rifle was 43" long and silencer 7" long. According to Malcolm Fletcher the gsw's inflicted to NB's lip and jaw were fired "when the rifle was within a few inches of the skin". This would mean the perp would need to hang over the end of the bed to inflict the facial shots. I don't see how NB was then able to swing around and expose his shoulder and elbow/chest in order to sustain the gsw's to these areas of his body. It would also mean the perp would need to relocate further away from the bed since these gsw's were inflicted when the rifle "was at least two feet from the body".
It is unclear whether June sustained 5 or 6 gsw's whilst in bed and getting out of. Even if we assume 5 only 8 casings were found either on the bed or to June's side of the bed. If NB was shot 4 x's whilst in bed and getting out of where is the missing 9th casing: 5 x June and 4 x NB?
Taking into consideration blood staining from June and SC's gsw's is it realistic to think NB's gsw's didn't produce any evidence of blood until he arrived on the stairs? Especially when the pathologist referred to the facial wounds as sites with a rich blood supply? Why ddidn't defence counsel ask the question...'could NB have sustained these wounds in the bedroom and left without a trace of blood until arriving on the stairs'? See attached.
