So the last time that Jim and Stacey Chapin saw their son Ethan alive, it was parents weekend at the University of Idaho.

They told me they left full of pride. Their three children, their triplets were living their best lives.

But that feeling was short-lived. It wasn't long after they learned that Ethan had been murdered in a quadruple homicide that thrust the town of Moscow into chaos.

And this morning, for the first time, the Chapin family tells the story of how they stayed afloat.

We just decided maybe it was best to tell our story of Ethan one, only just literally one time.

He deserves it. He deserves our story of him. This morning,

as the Idaho murder suspect prepares to accept a plea deal, the family of Ethan Chapin speaking

publicly together for the first time since Ethan, his girlfriend, Zana Kurnodal, and her roommates, Madison

Mogan and Kaylee Gonzalez, were brutally murdered in an off-campus home at the University of Idaho.

I miss him every day. When you lose your son at 20, you know, it's different. It's a different loss.

And I do, I miss him every single day.

And I always will.

Ethan, a triplet with his siblings, Hunter and Maisie,

all attending the University of Idaho together.

Hunter and Maisie and their parents, Jim and Stacey,

now telling their story in a new prime video docu series one night in Idaho, the college murders,

remembering their six foot four larger-than-life brother and son.

We played every sport together, every time we went in the car was together, party together. There was never a dull moment.

The night before Ethan was killed, Maisie brought him to her sorority formal. She now cherishes the text he sent her before bed.

So he started off by texting me. I think he said, dog, come hang out. We all want you here. And I said, I'm going to bed. And then he said, love you. And I didn't even respond to that. I think I was asleep by then. And that I love you kind of stood out, though. Well, yeah, yeah, definitely. Hunter, who pledged Sigma Kai with Ethan, says the next morning, a friend at the fraternity

woke him up saying the police were at Zana's house.

Hunter Johnson came out to me and said, I was like, where's Ethan and Zana?
