If there was DNA under a girl's fingernails, that would be the DNA used in the PCA. A small sample found on the snap of a sheath could have been left by a previous owner of the sheath, no way to know. If there was also DNA under a victim's fingernails, that would almost certainly be related to the attack and THAT would be the DNA they used. I would be interested to know if the judge that signed the arrest warrant questioned the officers on the items in the affidavit.
So, you're saying that Kohberger's DNA (on the sheath) was left on it by...him, right? It has to be him. Dabbing tiny amounts of single source DNA onto the use point of an artifact is not something that happens. The dabber would be breathing. THEIR DNA would be mixed in with the other person's DNA (unless they were wearing SCUBA gear or something).
It was just one person's DNA. Partial DNA from the real culprit would be there too, IMO (via their breath).
But the lab says plainly it was single source (one person).
I don't see how Kohberger's DNA could get on the sheath without Kohberger touching it. I assume there's more of his DNA in the leather (but there, we would expect to find bovine DNA as well and perhaps the DNA of a manufacturing worker - although it should be minute at this point and should match the genetic markers from the region of manufacture).
The sample on the sheath clearly belongs to Kohberger, so are you saying that he could be the previous owner of the sheath?
If true, then it's crucial that they have the Amazon records. I find it entirely too large a coincidence that Kohberger was at 1122 King Road both at the time of the murders AND a few hours later, after driving through Lewiston/Clarkston and back to Pullman. I find it too coincidental that his phone goes off just outside of Moscow and then, on the route he took home, it goes back on. Same timeframe.
I doubt there's any DNA under anyone's fingernails. BK was apparently wearing a dark outfit with sleeves, shoes, gloves and a partial face mask. Victims get DNA under their fingers by clutching into the wrists and arms (and sometimes hands) of the knife attacker.
I feel that if someone can argue that the sheath DNA is innocuous, that it is a small step to arguing that fingernail DNA is similarly objectionable (the argument would then become that perhaps BK and a victim were very well known to each other and had a lover's quarrel). But I don't think BK had any scratches, I'll be surprised if he did.
At any rate, single source DNA doesn't get on a sheath belonging to a separate person who breathes, IMO.
