The judge's comment about the fight in the kitchen undoubtedly taking place was misleading. It may have been a fight or a struggle, or a dying man staggering through the kitchen being bludgeoned.
Either the silencer was already attached or the only reason Sheila could have had to attach it would be for the twins not to wake up while being shot. After that she could have returned to June and Neville and delivered some point blank shots. She could have been hearing their voices taunting her even if they were dead. In a frenzy she wielded the rifle to strike Neville's body and scratched the mantle.
Then she may have crawled into the gun cupboard to hide. Then she realised how difficult it was shoot herself with the silencer attached and removed it, dropping it in the box with the bullets.
Bamber said the rifle did not have the silencer on when he left it.
That was very considerate of Sheila, putting on the silencer so not to wake the twins. Was Neville still sleeping then ?
Sheila took the silencer off, crawled into the back of the gun cupboard and dropped the silencer into it's box ? That clears that up that.
