On Nov. 13, 2022, University of Idaho students Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin were stabbed to death at an off-campus residence. The murders horrified the nation, resulting in numerous documentaries attempting to unspool the strange and unsettling tragedy. The latest, Amazon Prime Video‘s One Night in Idaho: The College Murders, promises to be one of the most exhaustive.
The four-part series comes from documentarians Liz Garbus and Matthew Galkin. The former, in particular, is a good fit for the topic, as her vast resume includes HBO’s I’ll Be Gone in the Dark (2020) and Netflix’s Gone Girls: The Long Island Serial Killer (2025), both of which explore horrific murders that turned into media frenzies.
“Told in captivating, tense, and emotionally wrenching detail by only those involved in and affected by the crime, the series intimately explores this American tragedy and its continued impact and fallout,” reads a synopsis, which notes that the series features exclusive interviews with the parents of Chapin and Mogen.
The series arrives just days after former PhD student Bryan Kohberger admitted to the murders in a signed confession. But who is Kohberger? Why did he do it? And where is he now?

Goncalves, 21; Mogen, 21; Kernodle, 20; and Chapin, 20, were found dead on Nov. 13, 2022, in an off-campus home where Goncalves, Mogen, and Kernodle lived with two other roommates. Chapin, who was dating Kernodle, was staying the night. Goncalves was sleeping in Mogen’s room, while Chapin was sleeping in Kernodle’s room.
According to CNN, a figure in a mask and dark clothing entered the house around 4 a.m. and stabbed the four students, moving from one room to the next. One roommate, Dylan Mortensen, testified that she saw the figure when investigating noises outside her bedroom door. Though she discussed what she saw with another roommate, Bethany Funke, nobody called 911 until roughly noon on Nov. 13, per court documents.
Two days later, the Moscow Police Department revealed that the murders were committed with an “edged weapon,” as reported by CNN, though no murder weapon was found.
On Dec. 30, a month and a half after the murders, police announced that they’d arrested a suspect, Bryan Kohberger, in Albrightsville, Pa., more than 2,000 miles from the site of the crime. He was later extradited to Idaho, per the New York Times.

At the time of his arrest, Kohberger was 28 years old and had recently wrapped his first semester as a Ph.D criminology student at Washington State University’s Pullman campus, a roughly 15-minute drive from Moscow.
Kohberger was formally charged with four counts of first-degree murder and one count of felony burglary on Dec. 20, 2022. According to CBS News, Kohberger’s lawyer claimed that his client denied allegations of his involvement in the murders.
But at his arraignment in May 2023, Kohberger refused to enter a plea, choosing to “stand silent.” On his behalf, the court entered a plea of “not guilty.” In April 2024, Fox News reported that Kohberger’s lawyers “firmly” believed in his innocence.
Speaking with CBS News, one of Kohberger’s neighbors in Pullman, Wash., said Kohberger brought up the murders in conversation just days after they happened. “[He] asked if I had heard about the murders, which I did,” they recounted. “And then he said, ‘Yeah, seems like they have no leads. Seems like it was a crime of passion.'”
While completing his master’s degree in criminal justice at DeSales University, Kohberger studied under Dr. Katherine Ramsland, who has written numerous books about serial killers, including The Mind of a Murderer (2011) and Confession of a Serial Killer: The Untold Story of Dennis Rader, the BTK Killer (2016). His studies included classes on forensic psychology, death investigation, and antisocial behavior, per NewsNation.
Though she described him to NewsNation as “a promising student who really could have made a mark in this career in a very positive way,” she said, “I have to look at the framework of what I taught and wonder, did I inspire him in some way?”
Kohberger’s reputation was less positive at Washington State University. According to the New York Times, he was terminated from his teaching assistant role in December 2022, a month after the killings. The firing followed investigations of his conduct around female students and a “verbal altercation” with a professor.
The Times also reported that Kohberger discussed “not being able to feel emotions” and feeling as if he could do “whatever I want with little remorse” in online forum posts from the early 2010s. He was also at one time addicted to heroin, per the Times.
In 2025, Kohberger’s lawyers revealed that he has autism spectrum disorder, which, as CNN puts it, would “explain what might be perceived as odd behavior as he sits at the defense table.”
What evidence links Kohberger to the murders?
While a motive for the crime remains elusive and no evidence shows Kohberger had any prior contact with the victims, prosecutors shared evidence they say ties Kohberger to the murders at a hearing on July 2, 2025, per the New York Times.
One key piece of evidence was a knife sheath left at the scene of the crime that had some of his DNA on it, which helped investigators “build a family tree that led them to Mr. Kohberger’s name more than a month after the killings.”

Prosecutors also cited video surveillance that depicts a car resembling Kohberger’s circling the neighborhood of the victims’ house before the murders. Also of note was Kohberger’s cell activity. While his phone was turned off during the murders, records later revealed that he was in the vicinity of the house in the hours after the killings but before the bodies were discovered.
As CBS News reports, prosecutors also allege that Kohberger bought a knife and Ka-Bar knife sheath — the same type of sheath found at the scene of the crime — online just months before the murders. Kohberger’s defense team planned to argue that the sheath “could have been planted by the real perpetrator.”
Where is Bryan Kohberger now?
On July 2, 2025, Kohberger pled guilty to all charges against him and submitted a signed confession in which he admitted that the killings were “willful, unlawful, deliberate, with premeditation and with malice afterthought.” He offered no reason as to why he committed the murders.
Kohberger’s plea deal allows him to evade the death penalty, which prosecutors would have pushed for had the case gone to trial, per CBS News. In exchange, the plea recommends Kohberger serve four consecutive life sentences for the murders and an additional 10 years for the burglary charge. Furthermore, he waives any right to appeal and will never be eligible for parole.
A judge will decide whether or not to accept the sentence recommended in the plea agreement at a July 23 sentencing hearing.
Currently, Kohberger is awaiting sentencing at Ada County Jail in Boise, Idaho.
