The blood evidence cannot be taken in isolation - it is attached to the existence of at least two different Parker hale silencers. Inside one of these silencers ('DB/1') that cops sent to the lab' on the 30th August1985, was the crucial dried flake of blood which produced the key blood group activity as a result of the flake being analysed between the 12th to the 19th September 1985. In stark contrast, human blood was found on the second silencer ('DRB/1') that cops sent to the lab' on the 20th September 1985, with specific instruction for it to be checked for blood. Both of these silencers originated from possession of the relatives. If these murders were only carried out by a single firearm, then why is it that blood in one form or another ends up in or on two different silencers, if only one silencer was supposedly found and recovered from the scene by relatives? Oddly enough, in September when David Boutflour contacted the police to tell them about him finding the silencer to 'the Gun's, he gives two possible locations inside the cupboard where he supposedly only found one silencer. Now, you do not need to be a brain surgeon, or for that matter a South Yorkshire police officer obtaining an extra pocketbook to rewrite his notes, to see that there is plainly something dramatically wrong with the 'one silencer' story. More significantly, in their haste to 'stitch' Bamber up as the murderer, the damn fools made a bollocks of attributing the key blood group evidence to 'the wrong silencer' ('DRB/1'), which as it turns out, did not even get sent to the lab' to be checked for blood, until after the flake had already been found and removed from the other silencer ('DB/1'), and the blood group evidence obtained from the flake - all done and dusted by the 19th September 1985, a day before the second silencer ('DRB/1') was sent to the lab' by cops to be checked for blood...
