Although I believe that the blood spot and ingrained paint were genuine, evidence of the hair is more of a head scratcher. Obviously the simplest explanation is that it got caught in the burred scratch on the moderator when/if Nevill was pistol-whipped in the face with the rifle barrel during the kitchen struggle. Possibly a three-quarter inch long, grey eyebrow hair. Then again, as David Boutflour didn't appear to see or mention it at WHF but Peter Eaton later did at Oak Farm, the hair from someone or something else might have become attached whilst in the car boot on the journey between farms, or during the couple of days before Stan Jones arrived to pick the moderator up. As DB noted that the moderator was sticky, perhaps the hair adhered tightly to it unseen at first and was only noticed as it became looser through handling.
Re the sound moderator and the reference to it being sticky.
If we look at the silencer in isolation, there was no reason why it should have had red paint on its knurled end or contain human blood within its baffles. We know it was human blood because of its enzyme characteristics, we also know the blood grouping to which it related. It is worth noting that Jeremy Bamber, being the only member of the family who routinely used the rifle, was unable to explain away these facts. An intruder would not have known where to find the sound moderator.
I have long wondered why the killer never cleaned the moderator prior to putting it back in the cupboard? Was this yet another fateful oversight on Bamber's behalf?
