No, I have seen photos of the sheath style of the knife referred to in the affadavit.
I've seen an image of both the knife and the sheath and I'm not disputing his DNA was on the sheath BUT it is a movable object which means finding it at the scene does not prove that BK put it there.
I believe forensics consider a finger print left in the victim's blood at the scene as pretty conclusive but for pretty much everything else the defence will find a way to explain it. The affidavit is very rich in evidence but you are filling in the blanks with logical conclusions and I'm pointing out they are not facts.
The affidavit says nothing about BK wearing gloves at the scene, how could it? We can speculate that gloves were worn because there is no mention of finger print evidence associated with BK at the scene but his finger prints might not be at the scene because he wasn't there. There is also no mention of fibre evidence on the sheath or damage to the sheath belt loop so how do we know it was attached to his belt and came off during a struggle?
As a PP said I'm not jumping to conclusions, just dealing with what we actually know so far. I wouldn't describe your posting as aggressive but "you could Google it yourself" is passive aggressive which is a bit unnecessary and assumes you have a superior knowledge.
I think what PP means is that you can't jump to conclusions when the actual truth isn't known. Such as you say the knife sheath must have been worn on a belt but we don't actually know if it was on a belt and was pulled off by one of the girls or whether he was just holding it in a gloved hand etc.
I'm not explaining myself very well
You're explaining yourself perfectly well and you understand the point I'm making.
