There's every possibility that the AK1 enzyme is rabbits blood. The jury were told that Sheilas' was the only blood that contained the AK1 enzyme too,,so take your pick-------Sheilas' or a rabbits ? Very debateable,,but almost likely to be from a rabbit. In actual fact there were two types of animal blood found,,but the jury weren't told about that at the trial,,nor was it entered into the forensic reports. Apparently it wasn't thought of as being relevant to the case.?? I know the matter was put to the CCRC at one time,,and no doubt it will crop up again at some point as there seemed to be a degree of uncertainty as to whether it was Sheilas' blood or not.
To be as indecisive as this doesn't sit well with the key " evidence " that got him convicted in the first place,,hence the reason why the trial was an unfair one.
A silencer wasn't used in the murders,,but possibly last used for killing vermin. ( rabbits )
The blood was tested and determined to be human blood not animal blood. The defense had their own expert go through the suppressor. He found microscopic blood droplets on the first 8 baffles. He determined it to be human blood not animal blood
He found the following components EAP BA, AK1, Hp2.1 and determined this meant it was group A human blood. these components can't be explained away as animal blood.
Sheila- EAP BA, AK1, Hp2-1
Neville- BAP BA AK1, Hp2-1
June- EAP BA, AK2-1, Hp2-1
The difference between June's blood and Sheilas is that Sheila had AK1 while June had AK2-1. That is why the distinction was significant.
