In Kansas, a former Marine was convicted at trial of stalking his estranged wife and then strangling her. Now, her son wants to put him on trial again.

If somebody hears this, thinks that maybe I know something about this, it could make all the difference. But before all that, we're heading to Idaho for a stunning development in the quadruple murder case that gripped and terrified the nation. It has been a little over a year since Brian Koberger stood before a judge and pleaded guilty to the murders of four University of Idaho students.

Kaylee Gonsalves, Madison Mogan, Ethan Chapin, and Zanna Kernodal. Did you, on November 13, 2022, enter the residence at 1122 King Road in Moscow, Idaho, with the intent to commit the felony crime of murder? Yes. In return for his plea, the prosecutor agreed to drop the death penalty, and Koberger was sentenced to serve four consecutive life sentences at a maximum security prison just outside of Boise.

The judge had these final words for him. The time has now come to end Mr. Koberger's 15 minutes of fame. It's time that he be consigned to the ignominy and isolation of perpetual incarceration. Now, it appears Koberger has changed his mind.

This week, he filed a petition with the court asking essentially for a do-over. He says he was coerced into the guilty plea, that he is innocent, and he wants a trial. Here to help us understand what this could mean for the case and the families is Dateline producer Shane Bishop, who has covered this story from the beginning. Welcome back to the podcast, Shane.

You bet. Hi, Andrea. Hey, Shane, before we get into what Koberger is claiming in this petition, let's rewind the clock. What evidence, Shane, did investigators say they had to zero in on Koberger? Well, the key piece of evidence was a drop of blood found on a knife sheath that detectives said the killer left near the body of Madison Mogan.

Analysts then used DNA and genetic genealogy to link Koberger to the knife sheath. And a search of Koberger's computer record showed that he'd purchased a K-Bar knife and a sheath just months before the murders. Koberger pleaded guilty just a few weeks before trial. The victim's families had mixed feelings about that.

We heard some emotional testimony at his sentencing. Let's take a listen. He is a hollow vessel, something less than human, a body without empathy, without remorse. He chose destruction. He chose evil. He feels nothing.

You'll sit with it long after this is over. That is your sentence. And it was written on the wall long before you ever pled guilty. You didn't win. You just exposed yourself as the coward you are. Then, fast forward a year, here comes this petition.

How much of a surprise was this to you, Shane? Well, I think it came as a complete shock. It certainly did to me. Although in my experience, it's hardly uncommon for convicted killers to arrive at a state prison to serve their life sentences and before long realize that forever is a long time, especially in a situation like Koberger finds himself in because he's in protective custody because of his notoriety and he's locked down 23 hours a day. Yeah, I didn't even realize he was in protective custody. Shane, walk us through this petition that he filed.

I think Koberger's most startling claims have to be that he is actually innocent and that he was pressured by his defense attorneys to falsely confess to these murders. Koberger writes in his petition that his counsel told what he calls elaborate lies to him about life on death row and promised him that a life sentence would mean a number of things, including immediate contact visits, freedom of movement inside the prison and employment. None of those are allowed when you're in the restrictive housing or protective custody like he is now. And the last thing Koberger claims is that his attorneys failed to disclose what he calls exculpatory evidence.

So just to be clear, Shane, exculpatory means evidence that Koberger is saying could prove his innocence. Does he go into detail about what this evidence is that he's talking about?
