Since this episode was recorded, there's been a major update. On July 2nd, 2025, Brian Colberger

pled guilty to four counts of first-degree murder and one count of felony burglary, avoiding

the death penalty. And just three weeks later, on July 23rd, he was sentenced to four

consecutive life sentences without

parole and an additional 10 years for burglary.

The court also imposed a $270,000 restitution and civil penalties.

that we understand the dark side. Now, during this episode, we'll examine that dark side.

In the early morning hours of November 13th, 2022, four promising college students were brutally stabbed to death

in an off-campus house in Moscow, Idaho. The victims, Madison Mogan, Kaylee Gonsalvis,

Zana Kernudel, and Zana's boyfriend, Ethan Chapin,

had their lives cut tragically short in a crime that would soon be called a quadruple homicide.

You've all heard about it. It shocked the nation. The community was stunned.

It was almost unthinkable that such a violent act could happen so close to the University of Idaho campus.

It would be one thing if this had happened in a busy, crime-ridden city.
