Not sure if the word here is ‘flaws’ ?
JM stated,
‘The reason for the flaws in the fingerprints was that during the fight with Mr Bamber a glove might have come off or been dropped and it might have rubbed Sheilas fingerprint off or have extra fingerprints on the gun which were ? ? Sheilas and would show up
That sounds like Jeremy had to wipe the rifle after the fight because his own fingerprints would have overlapped Nevill’s, proving he was the killer. Forensics would see by all the fingerprint patterns that Jeremy and Nevill struggled over the rifle. That’s why he had to wipe it clean of prints.
I can’t remember how many of Nevill’s fingerprints were found on the gun, but you’d imagine there’d be hundreds considering it belonged to him, and from memory, I think they only found a couple? And Sheila certainly wouldn’t have wiped them off.
Maybe JB was worried that he had no choice but to wipe the gun clean, and that should have alerted police as to why so few of Nevill’s fingerprints were on it.
Of course, after wiping it clean and having put his glove back on, he pressed Sheila’s finger onto it — just twice, I think? Which is also ridiculous. Sheila’s prints would’ve been all over it!
