Four Student Deaths, One Dark Mystery: The Untold Chapter of the Idaho Murders

Staff Report | PNN

Moscow, a small university town in the US state of Idaho, was quiet like any other night in November 2022. After a weekend of activities, some people returned from parties while others prepared for classes the next day.

But before dawn, a horrifying crime took place inside a rental house near the University of Idaho. In a matter of moments, four families lost their loved ones forever.

On the early morning of November 13, 2022, four University of Idaho students — Ethan Chapin, Kaylee Goncalves, Xana Kernodle, and Madison Mogen — were killed in a knife attack at an off-campus residence.

The brutal murders shocked not only the United States but also people around the world.

Following the killings, investigators faced numerous questions. Who committed the crime? Why were these four students targeted? What was the motive behind the attack?

Although investigators eventually identified the accused, the biggest question remains unanswered — why?

Netflix has explored the investigation, trial, and unanswered mysteries surrounding the case in a three-part documentary titled ‘The Idaho Murders: College Nightmare’, released on July 29.

The documentary highlights the horrifying details of the crime, key evidence from the investigation, the accused’s background, and the long journey of grief experienced by the victims’ families.

Initially, investigators had very few clues. There were no eyewitnesses, and the identity or motive of the attacker remained unknown.

The investigation took a major turn after a knife sheath was discovered at the crime scene. A small DNA sample found on the sheath helped investigators move toward Bryan Kohberger.

Surveillance footage showing a white vehicle near the area and cellphone location data further strengthened suspicions against Kohberger.

Police later arrested Kohberger after combining DNA evidence, vehicle movement records, and digital information.

In July 2025, Kohberger admitted responsibility for the murders. He was sentenced to life imprisonment without the possibility of parole for the four killings.

However, despite the legal conclusion of the case, the motive behind the murders remains a mystery.

The reason why those four students were chosen, why the house was targeted, and why such a brutal crime occurred have never been fully explained.

The documentary also explores Kohberger’s academic background. He was pursuing a PhD in criminology at Washington State University and had previously earned a master’s degree in the same field.

Former classmates claimed that Kohberger often wanted attention during discussions about serial killers and showed limited interest in others’ opinions.

Investigators also found that Kohberger had posted research questions on Reddit, claiming they were part of his academic work. The questions asked prisoners about their thoughts during crimes, victim selection, and planning methods.

Some participants in the documentary suggested that his interest in criminology may have gone beyond academic research, though no such theory was proven in court.

The documentary also includes allegations from some female students who said Kohberger’s behavior made them uncomfortable.

However, these claims represent personal opinions of participants and were not confirmed by a court ruling regarding the motive of the murders.

Although the verdict has been delivered, the grief and unanswered questions of the victims’ families remain.

Some family members expressed disappointment that Kohberger avoided the death penalty, while others felt that avoiding a lengthy trial helped families move forward.

In 2026, Kohberger gave an interview to The New York Times from prison, claiming he was innocent and saying mistakes occurred during the plea process. He has also appealed his conviction.

However, the court’s ruling remains in effect, and Kohberger is currently serving his sentence in a maximum-security prison.

Unlike many true-crime documentaries that end with the identification of the criminal and a court verdict, ‘The Idaho Murders: College Nightmare’ focuses on the unanswered question — why?

That unanswered mystery makes the documentary not only a reconstruction of a crime but also a story about human psychology, the limitations of justice, the pain of losing loved ones, and four young lives cut short.
