The Forensic Science Service (FSS) could not establish if the DNA was blood based

Overall the silencer is not going to solve anything its very possible Jeremy could have committed the murders without it. Hence why he keeps wanting it tested.
The silencer does not seem to prove guilt or innocence. Thou in a legal sense a pillar of the prosecution case will have collapsed.
Once again you ignore the facts after being spoon-fed with the correct information the last time you made this claim.
There was no DNA used at trial. Serology was used at trial, the blood in the moderator was group A human blood and a flake of this blood that was stuck between baffles 1 and 2 had an enzyme exclusive to Sheila so that both the crime lab experts and the defense's own blood expert said it could not have come from any individual except Sheila.
The depositing of the blood on the first 8 baffles is consistent with drawback. Sheila's fatal wound was determined to be virtually certain to result in drawback so her blood would have been found in the rifle if the moderator had not been attached when she was shot.
Her blood wasn't in the rifle but was in the moderator and thus establishes the moderator was used to shoot Sheila.
The DNA tests done in 2000 doesn't affect the above. The only DNA tests that could affect the above would be DNA tests of the blood removed 1985 and 1986 by the lab and defense expert Lincoln. But that blood was not DNA tested so there are no DNA tests to reference.
