Summary

Could a single knife sheath be the smoking gun that unravels the entire case against alleged killer Bryan Kohberger? The defense is working overtime to cast doubt on DNA evidence, arguing everything from privacy violations to the idea that DNA was planted. But when you leave your DNA at a crime scene—especially on something as damning as a knife sheath—can you really claim a right to privacy?

Retired FBI Special Agent Jennifer Coffindaffer joins Tony Brueski to break down the DNA debate, from the differences between blood and touch DNA to the defense’s attempt at turning word salad into reasonable doubt. Was genetic genealogy used appropriately, or did investigators bend the rules to get their man? And what about that mysterious glove—evidence or just a distraction?

As the trial looms, the prosecution seems confident in its case. But if Kohberger is convicted, will any of these arguments hold weight on appeal? Or is this just another desperate attempt to muddy the waters?

0:00.0	This is Hidden Killers with Tony Brewski. Here now, Tony Bruske. The other thing that I see a lot of
0:07.7	people asking is, okay, no match, but was this, I believe it was put into Cotis, I could be wrong.
0:15.9	Was it put into Cotis? And was it, did they look in the ancestral one as well just to give it a shot to see
0:23.0	where that could possibly go like they did with Kovberger? Okay, two answers to that. First of all,
0:29.7	100% they run it through KOTUS. That's just 101. You know, when you get a fingerprint, you run it
0:34.9	through APHIS. When you get DNA, you run it to Kodis.
0:38.4	Number two, do I believe they compared it against multiple DNA samples of others that were known to be in that house?
0:46.2	Yes.
0:47.1	Would they go through genetic genealogy?
0:49.8	I don't believe so.
0:50.9	First of all, it's extremely expensive, extremely time involved. And, you know, I think their
1:00.9	explanation is going to be what we've surmised. And that is you have one blood DNA sample on a railing at a party house. Not, in my opinion, it's not at the crime scene. It's not on one of
1:16.3	the victims. It's not on the bed. It's not on the knife sheath. It's not in and around. It's on a
1:22.0	railing that people would hold. If you have a hang nail, if you could get there. I mean,
1:27.2	come on.
1:28.5	So I think that it probably ended there.
1:33.3	Although, because they may be getting concerned about this becoming a huge issue, they may go that route.
1:43.3	They got to do what they got to do. I get it. She is the defense
1:46.4	attorney and she's doing a good job at it, trying to at least put reasonable doubt out there
1:51.1	into the public. The other thing that's been brought up, and I do know the answer to this,
1:56.4	but maybe you can give us a little better insight on it. Blood DNA versus touch DNA.
2:02.1	Now, on the surface, if you know nothing about DNA, it sounds like, well, one must be a lot
