So then is it possible that Sheila comes down, gets the weapon, goes upstairs intending to kill. Wakes her parents, threatening and abusing. Is it then possible that June tells Neville to ring Jeremy or the Police. He then goes down and makes the call to jeremy but after a few seconds on the phones hears the weapon being fired, goes up to find June has been shot and is then shot himself. Staggers downstairs where he is shot again after a struggle.
But does the cartridge evidence rule that out. Yes 13 cartridge shells were found in or just outside June & Nevills bedroom. The .22 Anschutz semi automatic hold a max of ten rounds I think so Sheila shoots June 7 times and Neville 4 times...does she reload after shooting June 6 times and Neville 4 times...has she got the extra shells for the reload on her person...or does she nip downstairs to reload..or was there only 9 shells in the .22 because Jeremy ejected one from the breech after going out to "shoot the rabbits".
So was it 5 into June and 4 into Neville and then the reload...and what was Neville doing during the reload..?
Was there more than one loaded magazine for this .22 weapon available to the shooter or did the magazine have to be reloaded one shell at a time.
Very difficult to work out the sequence of shots fired, taking into account the weapon had to be reloaded after 9 or was it 10 shots...and reloaded a second time as the bullet count was 25 in total I think.
Seems implausible that Sheila could reload if her father still had some mobility..
IMO, if Nevill did ring Jeremy, Sheila was not upstairs at the point - I don't think Nevill would have left June alone with Sheila wielding a rifle. She could, however, have been downstairs with the gun and then went upstairs and started shooting June whilst Nevill was on the phone - hence Nevill suddenly rushing off upstairs.
June was shot seven times in total, but not all at the same time. The killer came back later to shoot her again. She was shot several times initially, but she was able to get out of bed and walk around the bed. Nevill could have then come up the stairs and been shot four times either as he came up the stairs or when he got to the bedroom.
The magazine took ten bullets and there could be one in the breach - making eleven. However, I think there were maybe nine bullets in the magazine, which accounts for June being shot five times initially, and Nevill four times initially.
If Sheila did it, I think that she went downstairs because she ran out of bullets. Nevill went after her but he was very injured so couldn't do much. He was hit with the gun and then possibly collapsed in the chair. There was then time to reload the rifle and shoot him again with another four bullets.
