Hey everyone, I'm Ashley Banfield and this is Drop Dead Serious and God has it been a day.

It has been a day. But it is done. Brian Coburger has officially pleaded guilty to the brutal murders of four University of Idaho students.

And he did it in the very same Ada County courtroom

where both Lori Vallow and Chad Daybell were convicted,

practically in the same chair with the same setup,

the same rows of families and journalists

and even some of the same marshals in the courtroom. Except

unlike the Daybell murderers, Coburger was in the hot seat admitting his guilt out loud

to the courtroom, to the world. One by one, the judge asked him, did you kill Madison Mogan?

Did you kill Kaylee Gonzalez? Did you kill Zana Madison Mogan? Did you kill Kaylee Gonzalez?

Did you kill Zana Kurnodl?

Did you kill Ethan Chapin?

And each time, Brian Koberger looked forward and answered with the same word and the same tone.

Yes.

No hesitation.

No apology. No explanation. Just yes. Coburger's parents were there, in court, just feet away from him, seated quietly as their son, admitted to one of the most horrific and brutal crimes in recent memory.

I mean, this is in cold blood stuff.

Crimes like this do not come around often.

And there were Mr. and Mrs. Coburger having to face the reality,

that's my kid.

And he's admitting it.

Imagine what it was like being them.
