This is Hidden Killers Week in review.

I look back at the most prolific stories of the week.

This is Hidden Killers with Tony Brewski.

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-Koberger 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 Dreek, 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, you know, 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?

Wayway, Waiia?

It sounds Hawaiian, even though it's not. Wewai, I don't know the name of this park? Wayway, Waiya. It sounds Hawaiian, even though it's not.

Wewai, uh, yeah, I don't know the name. Wellaya, Waiia County Park. We're going to go with Waiya, Waya, 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 in the Moscow area.

That's just the name of the park.
