The three-part documentary “The Idaho Murders: College Nightmare,” released on Netflix, has brought renewed public attention to one of the most high-profile criminal cases in the United States: the murder of four University of Idaho students in November 2022.
The crime was discovered on November 13, 2022, at a rental home on King Street, just minutes from the University of Idaho campus in the small college town of Moscow. The incident had occurred in the early morning hours.

The victims were Madison “Mandy” Mogen, 21, Kaylee Gonsalves, 21, Zanna Kernodle, 20, and her boyfriend, Ethan Chapin. All four were found stabbed to death inside the house where they lived, while two other roommates survived.
Madison and Kaylee were close friends, while Zanna and Ethan were in a relationship. The young people had active social and university lives and were preparing to pursue their plans for the future.
The Night That Turned Into Tragedy
On November 12, Madison and Kaylee spent the evening in downtown Moscow. Meanwhile, Zanna and Ethan had spent part of the night at a fraternity party.
All four returned to the house in the early morning hours. Shortly before 04:00, Zanna received her food order.
Security camera footage showed that a white vehicle had passed near the house several times and returned to the area at around 04:04.
Prosecutors allege that Brian Koberger entered the house through the sliding kitchen door. He first went to the third floor, where Madison and Kaylee were, and then went down to the second floor, where Zanna and Ethan were.
At 04:17, a security camera at a neighboring home recorded a dog barking, voices or whimpering that could not be clearly distinguished, as well as a loud thud.
Just minutes after those recordings, the white car was filmed speeding away from the neighborhood.
The noises had awakened one of the two surviving roommates. After opening her bedroom door, she saw a man dressed in black whose mouth and nose were covered. He walked past her and left the house, while at that moment she did not know what had happened in the other rooms.
Authorities were notified at 11:58 a.m. following a report of an unconscious person. When police officers entered the house, they found that all four students were dead.
The murders caused immediate shock throughout the college town. For several weeks, authorities did not release the name of any suspect. Many students decided to leave the area temporarily, while others continued their classes remotely.
The case also gained enormous attention on social media. Numerous users analyzed photographs, videos and posts by the victims, while also putting forward theories that were not supported by facts.
At the same time, the investigative team analyzed hundreds of witness statements and many hours of security camera footage. A white Hyundai, similar to the car filmed near the house on the night of the crime, became one of the key focuses of the investigation.
The vehicle was found to be registered to Brian Koberger. At the time, he was 28 years old and was pursuing graduate studies in a doctoral program in criminal justice and criminology at Washington State University, which is located near Moscow.
Another important piece of evidence was discovered in Madison’s room. A leather knife sheath was found near her body, and investigators identified genetic material linked to Koberger on its metal clasp.
To verify this link, investigators retrieved an item from the trash at the Koberger family home in Pennsylvania. Genealogical research and genetic comparison initially linked the DNA on the sheath to his family and then to Koberger himself.
Cellphone data, vehicle movements and camera footage were also used to support the case.
According to prosecutors, during the crucial period when the attack occurred, Koberger’s phone was not connected to the network. The device became active again as the vehicle was leaving the area.
The data also showed that, in the months before the murders, his phone had been recorded near the victims’ neighborhood at least 12 times.
Despite this evidence, it was not established that Koberger personally knew any of the four students.
About six weeks after the crime, on December 30, 2022, Brian Koberger was arrested at his family’s home in Pennsylvania.
He was charged with four counts of first-degree murder and one count of burglary. He was then transferred to Idaho, where he remained in custody awaiting trial.
For more than two years, Koberger maintained that he was innocent. His defense challenged the legality of some of the evidence, the way genetic data had been used and the possibility that prosecutors would seek the death penalty.
Investigators were unable to find the murder weapon, and the motive for the killings was never clearly established.
Just weeks before the trial was due to begin, on July 2, 2025, Koberger changed his position and pleaded guilty to the four murders and burglary.
The plea agreement spared him the death penalty. Koberger accepted four consecutive life sentences without the possibility of parole, as well as an additional 10 years in prison for burglary. He also waived his right to appeal the decision.
The sentences were handed down by Judge Steven Hippler on July 23, 2025. During the hearing, the victims’ relatives spoke about the pain of their loss and the lives that Ethan, Zanna, Madison and Kaylee were unable to continue.
Koberger declined to speak in court and offered no explanation regarding the motive for the crime.
A new development in the case came on July 27, 2026. Koberger filed a motion for reconsideration, seeking to withdraw his guilty plea and go to trial.
He claimed that the attorneys who had previously represented him had misinformed and frightened him about the possibility of the death penalty, thereby persuading him to plead guilty.
These claims contradict statements he made in court in July 2025. At the time, Koberger said that he understood the agreement, that he was not under pressure and that he was pleading guilty because he was guilty. The judge has since approved the appointment of a new attorney to represent him.
The appointment of the new attorney does not mean that the guilty plea has been overturned or that another trial will automatically be opened. Koberger must prove that his previous legal representation was seriously inadequate or that allowing the guilty plea to stand would constitute a miscarriage of justice.
His attempt has angered the victims’ families. Shannon Gray, the attorney for Kaylee Gonsalves’ family, said that Koberger was trying to put himself back in the spotlight. It remains unclear whether the court will grant his request.
Although Brian Koberger has pleaded guilty and been sentenced for all four murders, the fundamental question remains unanswered: what was the motive?
It has not been established why he chose the house on King Street, whether he had stalked any of the students or whether one of them had been the initial target.
Prosecutors have not presented evidence proving a personal connection between Koberger and the four victims. Nor has a sexual motive been established.
For the families, friends and university community, the event remains the tragedy that forever changed the small town of Moscow. A memorial garden has been established at the University of Idaho, bearing the names of Ethan, Zanna, Madison and Kaylee in honor of the four young people whose lives were tragically cut short in November 2022.
As the new documentary brings the story back before the public and Koberger seeks to change the status of his case, the central mystery remains the same: why were four students murdered?
