This is Hidden Killers Week in review.

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

This is Hidden Killers with Tony Bruske.

Here now, Tony Bruske.

What if the man behind one of the most brutal college murders in recent American history

never had to explain why he did it. And never will. We're, of course, talking about

Ryan Coburger, the accused killer and the Idaho student murders who stunned everyone by pleading

guilty just weeks ago, sparing himself a trial and sparing the rest of us shot at getting answers.

No testimony, no cross-examination.

No, here's what I was thinking.

As if that would make any sense, anyhow.

Just a few cold words from a guy who once wanted to become a criminal psychologist

and now gets to study himself

in real time from a prison cell. But while the trial we were all bracing for may never happen,

the case is far from closed because here's the thing. The gag order is gone and in its place

we've got new evidence, new details and new ways to understand what happened that horrific

night in Moscow and how close Koeberger might have come to actually doing it again.

Do you want to mean today is someone who's been ahead of the curve on this whole thing, on the ground from the beginning.

Pulitzer Prize award winner and New York Times best-selling author and investigative journalist Howard Bloom is with us.

He's the guy who predicted a lot of this months before information has come out.

He's written extensively for airmail NBC's Dateline.

And his book, When the Night Comes Falling, has been looked at as a definitive account of the case thus far.
