Scipio you mention that there was no blood found in the silencer from Nicholas Caffell(and by assumption also twin brother Daniel). But didn't the perpetrator hold the ,22 anschutz with moderator attached close to the twins' heads,and what would have been the result were this to be the case? I'm also interested in the DNA from June being found in the silencer but none from Sheila,or have I not got this correct?
1) DNA
A) Prior to testing for DNA the moderator was tested for the presence of blood and tested negative thus if any DNA were found there would be no way to establish is was blood based and therefore no way to use such finding to establish the person's blood had bee inside the moderator. Thus the testing was pointless.
B) At least 3 DNA profiles were found in the moderator, it is possible they found 6.
They tested the baffles in 3 different sets, set A, B and C. Each set comprised different baffles.
Set A had 2 incomplete profiles and a near complete profile.
Sets B and C had 2 incomplete profiles and a near complete profile.
The least complete profiles had only 2 markers present so were of no use at all in trying to assess who they belonged to. It is possible for all 3 of these least complete profiles to belong to different people.
The least complete profile in Set A they could not even ascertain the gender of the contributor. Supposedly they were able to ascertain the gender of the contributors in groups B and C as being male.
The most complete profile in all 3 sets was determined to have been June's DNA.
The second most complete profile was female. It could have come from up to 3 different females though there was not enough to say the same profile was in each of the 3 sets.
Seven swabbings have been taken from internal parts of the moderator apart from the baffles. All seven results indicated that DNA from more than one person was present. The results were complex and incomplete and it was not possible to determine how many people had contributed to the DNA from the mixture. The predominant contribution appeared to have come from a female or females.
In addition 7 different swabbings were done of the other internals of the moderator (internals other than the baffles)
Sheila's DNA profile was detected in 5 of the 7. The remaining 2 had components which matched Sheila , but not at all of the ten areas of DNA markers available for comparison so the match was not as conclusive.
The expert said it was enough to say Sheila's DNA was present but didn't have the knowledge to calculate the statistical odds. The COA reduced this from Sheial's DNA definitely being present to might have been present in order to give Jeremy the best benefit possible. They did so fully knowing it made no difference though so it was not really them being as generous as they made it seem.
C) The boys' wounds were far enough away they would not result in drawback. Furthermore, 22 shots to the skull do not usually result in backspatter it takes larger rounds to accomplish such because of the nature of the area. That is why I don't include their blood as necessarily being on the killer. The killer definitely would have had high velocity spatter from Nevill and June (because of the location of some of their wounds and distance of those shots) but it is possible that no spatter from the boys got on the killer. It is possible spatter got on the killer from them but it is not that likely so far from a sure thing.
For their blood to get in the weapon it had to be fired at 1mm or less from their bodies which didn't happen and even if that had happened the shots in the locations where they received them would still not have necessarily resulted in drawback.
The unknown male DNA found in the moderator could have been from one of them for all we know. We don't know whose DNA the unknown profiles were from. Who they belonged to makes no difference at all because it can't be established it was blood based and even if it was blood based that sill doesn't have any bearing on the blood already removed which is what matters. The only DNA test that could actually matter would be a DNA test of the blood that was removed in 1985 and 1986.
