This is Hidden Killers with Tony Bruske.

Here now, Tony Bruske.

Well, there's been a lot of question for a lot of time about what happened to that K-bar knife that Brian K-Berger used, and possibly another weapon that was used in the slings of those four innocent,

those four innocent college students in Moscow, Idaho, several years ago.

He's obviously spending the rest of his life in prison.

We've gotten a lot of information from document dumps about how that early investigation went,

learned more about Koeberger, what he was like before, after, during the trial.

But what about the weapon?

What about what else he was doing out there?

Robin Drake, retired FBI Special Agent, Chief of the Counterintelligence Behavioral Analysis Program,

has some theories. And we've been talking

about this for a bit off the year. You've laid out a theory that reframes how we think about the missing

K-bar. Instead of a panicked dump just tossing it out the window or into a river, you're looking at

something much more deliberate, a tactic straight out of the playbook of offenders like Israel Keys, where a location isn't just scenery. It's part of the operation. I got to ask you, how the hell do we say the name of this park? Waiway, Waiwia. It sounds Hawaiian, even though it's not. Wewai, I don't know the name. Waiia, Waiia County Park. We're going to go with Wauia, Waiia County Park. I think that's how you'd say it if you were in Hawaii. I could be completely wrong. Even though we're not talking about Hawaii. This is right there, uh, in, uh, the Moscow area. That's just the name of the park. Wai'ia County Park isn't just a quiet riverside for stargazing.

It could be pre-selected pre-selected pre-prepping spot for him before his excursions and maybe more than just the one that night.

Let's start by dissecting the tactical side here, the terrain, his patterns, and the criminal tradecraft that might point us towards where that

knife currently is. What brought you into this line of thinking that maybe, you know, maybe he's got

a hidey hole kind of BTK-ish or Israel Kees-ish? Give me your thoughts. Yeah, Tony. So this was,

this came about just from all the data points and statements that everyone's making along this entire road.

And I remember just sitting with you and watching live the, you know, the victim statements during the sentencing.

And it kind of hit me, hit us already on this one, but kind of hit me hit us already on this one but kind of hit me even

harder i think that wow this guy has not done an original thing during this entire process you know
