Nearly four years after the grisly crime that garnered national attention, the question still remains: What drove Bryan Kohberger to brutally kill four students at the University of Idaho in 2022?
While the convicted killer has yet to provide any hints himself, a new Netflix documentary hopes to shed new light on Kohberger’s motivations and provide a deeper look into the lives of the four students who were murdered. The Idaho Murders: College Nightmare begins streaming on Wednesday, July 29, and features “unprecedented access to police footage, plus archival materials and firsthand accounts from the victims’ families,” according to Tudum.
While executive producer Joe Berlinger has confirmed the three-part project focuses primarily on the four victims—Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin—Kohberger and his behavior preceding the murders will likely face new examination. The killer is currently serving four consecutive life sentences for first-degree murder as part of a 2025 plea deal with prosecutors.
Earlier this week, Kohberger spoke publicly about his conviction for the first time, telling The New York Times he filed a petition in court to rescind his guilty plea and go to trial instead—putting the case back in the spotlight.
Ahead of the documentary, here is everything you need to know about Kohberger’s background, the murders and subsequent investigation, and Kohberger’s life in prison today.
Who Is Bryan Kohberger?
Bryan Christopher Kohberger was born on November 21, 1994, and was raised in the Pocono Mountain communities of Albrightsville and Effort in Pennsylvania.
Former neighbors remembered Kohberger as a “quiet, heavyset boy who was picked on for his weight,” according to the Idaho Statesman. He attended Pleasant Valley High School, graduating in 2013.
Friends and classmates said Kohberger began kickboxing and running sometime around his junior year, leading to considerable weight loss. Along with the physical changes came a shift in personality. “It almost seemed to me he had a desire to be the alpha,” a former friend named Thomas Arntz said. “For no reason, he’d try to grapple me and put me in headlocks when I didn’t want to. He tried to portray it as just boys being boys, but that’s not the way I ever took it.” Kohberger also expressed an interest in working for law enforcement.
Other friends allege Kohberger smoked marijuana, and that his drug use spiraled into a heroin addiction. However, he seemingly changed his lifestyle, later working a job as a security officer for the Pleasant Valley School District.
Kohberger earned a bachelor’s degree in 2020 and a master’s in 2022 from DeSales University in Center Valley, Pennsylvania, and started in Washington State’s criminal justice and criminology PhD program in August 2022. Interview documents released by Idaho State Police revealed students and faculty showed concerns about his conduct. The school received nine separate complaints accusing him of “rude and belittling behavior toward women.” One faculty member worried Kohberger might stalk or sexually abuse students should he ever become a professor himself.
All of this came to a deadly crescendo just a few miles away in Moscow, Idaho, with the 2022 University of Idaho killings.
What Happened During the Idaho Murders?
On November 13, 2022, four University of Idaho students—Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20—were murdered in an off-campus residence in Moscow. Goncalves, Mogen, and Kernodle were roommates. Chapin, Kernodle’s boyfriend, was staying in the home on the night of the attack, as Biography.com previously reported.
We now know from unsealed autopsy records the victims had at least 150 combined stab wounds. Kernodle was stabbed 67 times, Goncalves 38 times, Mogen 28 times, and Chapin 17 times. The report found all four died primarily of multiple sharp force injuries.
While the actual blade believed to carry out the killings was never found, investigators found a KA-Bar knife sheath inside the house—possibly left behind from the killer’s confrontation with Kernodle. This piece of evidence ended up providing the trace DNA used to ultimately link Kohberger to the crime scene.
How Was Bryan Kohberger Arrested?
On November 29, Kohberger was officially named a person of interest. Cellphone records revealed Kohberger’s phone was close to the crime scene between 9:12 a.m. and 9:21 a.m. the day of the murders and had been near the residence at least a dozen times before.
By the following month, Kohberger had returned to his parents’ home in Albrightsville and was under surveillance. Authorities collected trash samples from the residence, which were used to build a DNA profile showing a near-certain probability of a familial match with the knife sheath. This means there is a very high probability of a match to the person who left DNA at the crime scene.
On December 30, 2022, Kohberger was arrested at his parents’ home and charged with four counts of first-degree murder and one count of felony burglary. He was extradited to Idaho and held without bail.
What Was Bryan Kohberger Convicted Of?
Forgoing a preliminary hearing, prosecutors took the case before a grand jury. On May 17, 2023, the jury returned an indictment of the same charges already levied against Kohberger: four counts of first-degree murder and one count of burglary.
Kohberger stood silent at his arraignment, meaning he didn’t enter a plea. A judge submitted a “not guilty” plea on his behalf.
The following year, the district judge overseeing the case ruled prosecutors could seek the death penalty against Kohberger if he was convicted. The defense team later appealed, saying Kohberger’s diagnosis with an autism spectrum disorder “reduces his culpability, negates the retributive and deterrent purposes of capital punishment, and exposes him to the unacceptable risk that he will be wrongfully convicted and sentenced to death.” However, the ruling was upheld.
Ultimately, rather than go to trial and face the death penalty, Kohberger took a plea deal with prosecutors. On July 2, 2025, he pleaded guilty to all five counts—including the four for first-degree murder. The agreement stipulated four life sentences running consecutively for each murder, without chance of parole.
However, in July 2026, Kohberger provided a statement to The New York Times saying he planned to seek postconviction relief in court and rescind his guilty plea in favor of a trial. He claimed his plea was based on “false promises” and wrong information from his attorneys.
“My actual innocence is my truth, and the plea, hinged on by false promises and blatant disinformation, MUST be withdrawn,” Kohberger said.
Where Is Bryan Kohberger Incarcerated?
Kohberger is currently serving his life sentence at the Idaho Maximum Security prison located in Boise. He is kept in the facility’s J Block, according to the Idaho Department of Correction.
In February 2026, Court TV reported a source with knowledge of the Idaho prison system said the state had considered transferring Kohberger to another facility through an Interstate Corrections Compact agreement. The cited reasons were overcrowding of inmates and staffing shortages. However, Kohberger has yet to be moved.
What Is Bryan Kohberger’s Life in Prison Like?
The J Block is a high-security area where Kohberger and other inmates live in single-person cells, are transported in restraints, and are allowed one hour of recreation daily, according to KMTV11.
Kohberger has reportedly expressed numerous complaints to prison staff about the conditions there. Cold Case Foundation director Chris McDonough told NewsNation in December 2025 that Kohberger was unhappy with the quality of the bananas served to inmates, and previously alleged he didn’t receive all of the food allocated to him.
Kohberger has also claimed he received threats of sexual assault and “minute-by-minute” verbal harassment from inmates. He requested to be removed from the solitary confinement section of the prison, but this petition was denied.
Soon after Kohberger’s arrival at the prison, video footage appearing to show the killer inside his cell was shared publicly. Officials initially thought the footage may have been made with artificial intelligence, but eventually determined it was likely real and in violation of policy—prompting an investigation into the purported leak, according to A&E.
We must wait to find out if the Netflix documentary offers even more details about Kohberger’s daily routine.
What Happened to the Idaho Murders House?
In December 2023, the University of Idaho demolished the off-campus home where the murders took place. The home’s previous owner had donated the property to the school, and it was already scheduled to be razed months prior, according to CNN. However, it was kept standing to allow both prosecutors and defense attorneys access.
Family members of Goncalves and Kernodle argued the home should be preserved, claiming it could provide evidence during a trial for Kohberger.
Conversely, university spokesperson Jodi Walker called the site a “daily reminder of the horrific event that happened there.”
Associated Press video footage from July 2025 showed the site vacant with small memorial items left in memory of the victims.
More recently, the families of all four victims sued Washington State University, where Kohberger was pursuing his doctorate at the time of the murders, for damages. They allege the school remained “idle in the face of known extreme and repeated instances of discrimination, sexual harassment, and stalking by Kohberger occurring in its educational program.” The case is scheduled to go before a jury on September 13, 2027.
