Why would Jeremy need to check to see if Neville is still alive if he rests motionless shot in head and face five times? There is no rational reason to inflict those marks, This indicates the perpetrator was irrational.
You know there is no way Sheila would burn Neville's back. It is another preposturous suggestion.
She didn't have time to do all the things she was supposed to have done, (22 minutes) prior to the police arriving. Now she was supposed to have taken the silencer off to burn Neville's back.
Bamber had either already taken the silencer off when he realised upstairs that he had to. Or took it off to burn Neville's back to check for signs of life. This is just as easy as reloading and shooting Neville again.
The silencer was not cleaned by Bamber for several reasons, the latest strong reason given by NGB last week. It was then put away, for several more obvious reasons.
