Where?
The more I see regarding Bambers claims of innocence, his CT vlogs, blogs and letters etc, the stronger my belief on his guilt becomes..
The provable facts I am referring to are there for all and everyone to see. To simplify, one parker hale silencer, SBJ/1 (22), found on 10th August 1985, taken to lab' by Cook for the attention of Howard, who detects human blood. She states there is insufficient blood for testing purposes. Gives SBJ/1 (22) back to Cook, who says he proceeded to carry SBJ/1 (22) around in his coat pocket for the next 17 days. On 15th August 1985, Cook exposes SBJ/1 to the harmful superglue treatment, damaging any prospect of getting any uncontaminated blood group, or much later, uncontaminated DNA results. Still, whilst Cook still retains possession of SBJ/1 (22) he proceeds to strip it down, dismantling it, piece by piece, until he has demonstrated no presence of blood anywhere amongst the separated baffle plates. He photographs all of this. He doesn' t see any blood, he doesn't find any blood. He rebuilds the silencer, and then afixs it directly onto the screw thread on the end of the rifles barrel. What Cook then does is he takes another photograph showing the rebuilt silencer (SBJ/1 - 22) screwed onto the barrel of the gun. What he then purports to do is, he resubmits SBJ/1 (22) back to the lab' on the 30th August, 1985, disguised as DB/1 (23). He already knows there is no blood inside it, because he had stripped it down, examined it with close scrutiny, and took a photograph confirming what he himself had done. Anyway, nobody knows what the lab' did with DB/1 for the next 13 days, until suddenly there is a rush of activity on the 12th September, 1985, with the restripping of DB/1 by Fletcher and Hayward, and the astonishing discovery of the flake of dried blood trapped between baffles 1 and 2. Testing of this flake took place over the next seven days or so. So that by 19th September, 1985, blood expert, Hayward, had obtained 4 distinctive blood groups (A, EAPBA, HP 2-1, and AK1). But, these results were known to be potentially problematic, for example, having been obtained from inside a silencer (DB/1) which had been exposed to the harmful effects of cynoacrylate fumes...
My best guess, is that when 'Ron' Cook dismantled SBJ/1 as mentioned, that he used blood taken from the third blood sample obtained from the neck of Sheila Caffell during autopsy performed on 7th August 1985, and dripped some of this uncontaminated blood belonging to her, onto the baffles before rebuilding it. The problem he had however, was that he placed uncontaminated blood belonging to Sheila, inside DB/1 (23), which had got contaminated baffle plates, which if the matter had not been addressed would stand out as a deliberate attempt to pervert the course of justice...
That was why, the second decoy silencer (DRB/1) was sent to the lab' on the 20th September, 1985. It was sent because it was needed to become the carrier of Sheila's blood, in an uncontaminated environment (DRB/1). Police / relatives deliberately used this second decoy silencer (DRB/1) to make fresh scratch marks on the kitchen aga back at the farmhouse, because Cook believed that exposure of SBJ/1 (22), to harmful superglue treatment carried out on 15th August, 1985 may have irreparably damaged paint on SBJ/1. So they made new scratches on the aga surround, and sent DRB/1 off to the lab' on the pretense of it being checked for blood and fibers...
The rest is history...
