Once a quiet criminology PhD student, Bryan Kohberger has now been sentenced to four consecutive life terms after newly unsealed documents revealed the full horror of how he brutally murdered four University of Idaho students—leaving behind a shattered community and haunting questions that may never be answered.

Nearly three years after the brutal stabbing deaths of four University of Idaho students shocked the nation, newly unsealed documents have exposed the full, chilling details of the crime—and the disturbing behavior of the man behind it, Bryan Kohberger.

The documents, made public on July 23, 2025—just hours after Kohberger was sentenced to four consecutive life sentences without parole—shed light on the savagery of the November 13, 2022 murders and the calculated mind of the 30-year-old criminology student turned killer.

According to the files released by Moscow Police, Kohberger used a suspected Ka-Bar combat knife with overwhelming force to butcher Xana Kernodle, Kaylee Goncalves, Madison Mogen, and Ethan Chapin inside their off-campus home in Moscow, Idaho.

The attacks, described in grim detail by officers who responded to the scene, paint a nightmarish picture of what unfolded that early morning.

Xana Kernodle, 20, was found in a second-floor bedroom, lying on her back in blood-soaked underwear and a shirt. She had sustained over 50 stab wounds, including two that pierced her heart.

Police reported signs of a desperate struggle: deep cuts on her hand, blood spatter across the walls, and furniture overturned in what appeared to be a violent fight for her life.

Ethan Chapin, 20, her boyfriend, was found dead in the same room, partially covered by a blanket, with arterial blood spray visible near his head.

On the third floor, Kaylee Goncalves and Madison Mogen, both 21, were found in bed together. Goncalves had been stabbed more than 20 times—her body described as “unrecognizable” due to the damage to her facial structure.

She had sustained injuries to her lungs, liver, and major arteries, along with blunt-force trauma and asphyxiation.

Mogen was also fatally stabbed, covered in a blood-soaked pink blanket. Goncalves’ beloved Goldendoodle, Murphy, was found at the scene—unharmed but visibly traumatized.

One haunting detail the documents reveal is how Dylan Mortensen, one of two surviving roommates, told a friend she had seen a masked man in the hallway but failed to call 911. The filings claim Mortensen was intoxicated and too frightened to confront what she witnessed.

Instead, she locked herself in a room with fellow survivor Bethany Funke and texted a friend to come check the house. The friend never arrived. It wasn’t until later that the four bodies were discovered.

While the Ka-Bar knife sheath was found at the scene, the murder weapon itself was never recovered—an eerie reminder of the unfinished pieces of this puzzle.

The unsealed files also contain interviews with inmates who shared space with Kohberger after his arrest.

One described him as “a f–king weirdo,” noting his obsessive hygiene habits—washing his hands dozens of times daily, spending nearly an hour in the shower, and sleeping irregular hours.

Another inmate claimed Kohberger would spend hours video chatting with his mother and rarely interacted with others.

A former teaching assistant who worked with Kohberger at Washington State University, where he was pursuing a PhD in criminology, said Kohberger had scratches on his hands and face in the days following the murders.

When questioned, Kohberger claimed he’d been in a car accident, brushing off the concern.

The TA also reported increasingly inappropriate behavior toward female students—another chilling red flag missed in hindsight.

During Kohberger’s first police interview in December 2022, held at his parents’ home in Pennsylvania, he chatted about school and said he’d learned about the murders from a campus alert.

When detectives probed deeper, he quickly invoked his Fifth Amendment rights and requested an attorney.

At his sentencing on July 23, Kohberger showed no remorse. When asked if he had anything to say, he uttered just three words: “I respectfully decline.”

His silence followed nearly three hours of emotional testimony from grieving families. Steve Goncalves, Kaylee’s father, confronted the killer directly: “You’re a joke… Today, you have no name. Nobody cares about you. You’ll be nothing but two initials forgotten to the world.”

Survivor Dylan Mortensen broke down as she faced Kohberger in court, calling him a “soulless killer” who destroyed the lives of her best friends.

Though Kohberger has been sentenced and will never walk free again, the question of “why” still looms. He was never required to provide a motive as part of his plea deal—and offered none.

The unanswered questions, along with the freshly revealed horrors of that night, leave behind a deep scar on the Idaho community, and a reminder that evil sometimes wears a scholarly face.
