Early in the morning of November 13, 2022, University of Idaho students Madison Mogen and Kaylee Goncalves, both 21, and Xana Kernodle and Ethan Chapin, both 20, were stabbed to death in their off-campus house in Moscow, Idaho. The brutal deaths in an otherwise peaceful college town shocked the nation.

DNA evidence found on a knife sheath left at the crime scene soon led police to Bryan Kohberger, a Ph.D. student in criminal justice and criminology at Washington State University, located just a few miles from Moscow in Pullman, Wash. On December 30, 2022, Kohberger was arrested. He was subsequently charged with the four murders.

Kohberger, now 30, was scheduled to go on trial in Idaho in August 2025, but in June, he and the state reached a plea deal that allowed him to escape the death penalty. Since reporting to the Idaho Maximum Security Institution, Kohberger has encountered myriad problems, and new information about his life and behavior has been made public.

Bryan Kohberger Never Explained Why He Killed

On July 2, 2025, Kohberger pleaded guilty to killing the four students. On July 23, he was handed four life sentences with no possibility of parole, as well as a 10-year sentence for one count of burglary. His life sentences will run consecutively.

Kohberger didn’t provide any explanation for his crimes, disappointing some family members of his victims. The plea deal could have required this, but prosecutor Bill Thompson said he didn’t trust Kohberger to be honest about his motive. Thompson added, “I don’t believe there is anything that would come out of his mouth that wouldn’t be self-serving, and I don’t believe that there’s anything that would come out of his mouth that would not further victimize the families.”

After sentencing, Kohberger transferred to the Idaho Maximum Security Institution, a state prison in Kuna, near Boise, where he is inmate #163214.

Living in Solitary Confinement

Kohberger was initially evaluated in a medical transition unit inside the prison. On July 29, he was sent to long-term restrictive housing, or solitary confinement, on the J Block unit, where he remains in his cell 23 hours a day and has one hour of outdoor recreation. “Incarcerated individuals in long-term restrictive housing live in single-person cells, are moved in restraints and are provided showers every other day,” according to a statement from the Idaho Department of Correction.

Individuals in this type of confinement are able to place commissary orders and access religious services and can use communication services.

J Block can hold up to 128 individuals. The prison’s full capacity is 535.

Trouble Adjusting to Prison Life

After arriving on J Block, Kohberger complained that fellow inmates were taunting him at all hours. Although he has a one-man cell, the men incarcerated in his prison often communicate with each via air vents. Former detective Chris McDonough, who now works with the Cold Case Foundation, told The Daily Mail that the inmates “joined forces” in their “relentless” targeting of Kohberger.

“It’s driving him crazy,” McDonough said. “The inmates are tormenting him at night and almost all hours of the day—taunting him through the vents in his cell.”

Kohberger has filed complaints that other prisoners flooded his cell, his meal trays have been missing some items and he’s received threats of 𝒔𝒆𝒙𝒖𝒂𝒍 𝒶𝓈𝓈𝒶𝓊𝓁𝓉. In a report, a corrections officer confirmed that Kohberger was threatened with vulgar language, but the officer could not identify the person speaking.

The Idaho Statesman also reported that, because Kohberger requested protective custody, the prison held a hearing on this matter on August 12, 2025. During the proceedings, Kohberger admitted he would likely become less of a target as outside interest in his case faded. Officials decided to leave him on J Block.

Also in August 2025, videos that seem to show Kohberger in his prison cell were shared publicly soon after he arrived at the state prison. Officials initially thought the videos could be AI but by September had determined the footage was likely real. Making and distributing videos of prisoners violates policy, and an investigation is underway to determine who may be responsible.

Following the case’s adjudication, Idaho State Police and the City of Moscow Police Department released information gathered during the investigation. The newly public reports and photos include details that do not offer an explanation for Kohberger’s actions but provide some insight into his life and behavior before and after the murders.

Police photos taken in Kohberger’s apartment show books and papers related to his criminology studies, as well as personal items like birthday cards and vegan-friendly frozen pizza. The prosecutor said the apartment had been thoroughly cleaned and contained “nothing of evidentiary value.”

Police interviewed multiple people who’d gotten to know Kohberger in the fall of 2022 during his first semester as a grad student at Washington State University. Several described his antagonistic behavior toward women: One said she’d witnessed Kohberger blocking a female coworker at her desk area, and that he’d followed her and her coworker to their cars. Kohberger also once prevented a woman from leaving class. As a teaching assistant he was seen acting inappropriately with female students. Interviewees also related that he was often late to classes with female instructors but not male teachers.

While discussing the Moscow murders with a fellow Ph.D student, Kohberger shared his opinion that the killer “must have been pretty good.” In a conversation about whether the murderer would be 𝒄𝒂𝓊𝓰𝒉𝓉, Kohberger “said maybe it was a one-and-done type of thing.”

This student also told police that at school Kohberger had been interested “in the emotions of what it felt like when committing a crime.”
