So that first shot on Sheilas' neck was about 3 or 4 inches away. Easily done if the shooter is in a seated position with the perpetrator standing over him,,but not easy with a rifle to inflict oneself. My guess is that Neville had hold of the rifle at this point after having been badly injured himself.
Fingerprints of an unknown origin and also blood was found on the rifle butt.To my knowledge,Nevilles' hand/s weren't forensically tested for lead,,unless Essex police know differently in their " hidden files " which they won't release.?
That second shot to Sheila wasn't done by herself. I would say it happened about 7.30/8.45am. Jeremy was outside,shivering in the cold.
