Hi. New here and following all the points closely.
Can anyone explain if it was only semen DNA that was found on Alesha? Can you even distinguish between different bodily fluid types?
I’m not saying AC didn’t rape and murder but just wondered How conclusive the DNA evidence was.

I am not sure whether it's possible to differentiate between sources of DNA (semen versus e.g. skin or saliva etc). Different people say different things. But given the large number of injuries, the number of points on Alesha's body on which the prisoner's DNA was found (14? a lot, anyway) and the lack of any other alien DNA found at the murder scene, it seems highly unlikely that anyone other than the prisoner was involved.
Put bluntly,
vide the defence narrative, if the prisoner had been 'framed' by a third party 'planting' the DNA via a used condom, it is very unlikely, in my understanding, that other DNA, or indeed lubricant / spermicide, would not also be present at the scene. And no such material was reported.
Other problems with the defence narrative include the CCTV evidence regarding the prisoner, the forensic evidence related to the discarded clothing understood to be his, and the lack of evidence of any attack / injury in the flat from which Alesha appears to have been taken.
The defence narrative also fails to explain why a knife, apparently from the prisoner's house, ended up on the shore near the site of Alesha's abduction.
Let's spell out another thing - and if this is out of line, I hope the moderators will remove it. But as we all know, in cases of child murder, close family members are most likely to be guilty, hence the first to be investigated. The police on Bute aren't idiots, are they? I suspect they, too, ran through - because they had to do so - a theory that either RM or someone else in Alesha's household that evening might have committed the relevant crimes. Ultimately, with access to forensic material and also the ability to question whoever they wished, they pursued charged against the person now convicted of those crimes. I trust that they did the right thing, based on evidence, experience and probability.
