Exactly as I stated, there was no blood on Sheila Caffell's inner hand or fingers associated with any criminal activity. The only blood on her hands was on the back having come into contact with her bloodied nightdress.
NO EVIDENCE WHATSOEVER to sustain any claim that Sheila Caffell wielded the rifle.
Glad we could clear that up before lookout got too excited! 
Stop having yourself on, the blood got onto the top part of Sheila's hand whilst she was ' trying to throttle' her mother. Look, anybody can replicate what Sheila did to June, and get the same or similar marks on the top of the right hand, depending of course upon there being blood on the neck, similar to that which was present on June Bambers throat when Sheila grabbed her. Providing there is a supply of fresh blood higher up on the neck above where your hand gets positioned, the blood will automatically run or transfer onto the top part of your hand, just as it did with Sheila's hand. There are experts in blood staining and I am convinced that he or she will conclude that Sheila had indeed tried to throttle her mother, at a time when for one reason or another, the loaded anshuzt rifle was 'not availabe' to Sheila for her to shoot her mother at 'that' moment. Sheila had then subsequently wiped her hand on the front of her nightdress. As to how long afterwards, did Sheila take up possession of the rifle again, is any bodies guess, but she did handle the rifle after trying to strangle her mother. We know she did because I can't see Sheila trying to throttle her mother who would have been shot a total of 7 times in that scenario, once between the eyes. No, June was attacked by hand before she got finished off, and I believe that Sheila shot her two boys after trying to strangle her mother, then Sheila returned to her mother and finished her off. Then at about 7.15am, Sheila was persuaded to show the rifle in her possession as a gesture of goodwill because cops were wanting to gain access for the ambulance and its crew. Sheila appeared to be cooperating in this regard because she placed the said rifle at an upstairs window, then she made her way downstairs intending to unlock the back door, but armed cops smashed the door down, and were trying to force their way into the kitchen, which infuriated her because cops had convinced her that she could trust them. She grabbed the barrel of the cop gun as it appeared around the outside edge of the inner kitchen door and there was nothing PS Woodcock do do about it because at that time the muzzle of his gun was always pointing toward the outer wall of the kitchen, until he got around the edge of the door. However, at the precise moment that Woodcock thought he was about to reach that point,, the muzzle of his gun was pointing in the general direction of Sheila. But she made a sudden movement by trying to yank the gun out of his possession, which caused the weapon to discharge a solitary shot across Sheila's neck...
