What He Did
In the early morning of November 13, 2022, Kohberger entered a rental house at 1122 King Road where six University of Idaho students lived. He killed four of them with a large fixed-blade knife: Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20. All died of multiple stab wounds while on or near their beds.2NBC News. Idaho College Student Killings Summary and Timeline
According to prosecutors, Kohberger entered through a sliding door just after 4:00 a.m. and went directly to the third floor, where he killed Mogen and Goncalves in their sleep. Kernodle was awake on the second floor and appears to have encountered Kohberger as he came back down the stairs. She fought back, suffered more than 50 stab wounds, and had defensive injuries to her hands. Her boyfriend, Chapin, was asleep in her bedroom and was killed there.3People.

Two other roommates, Dylan Mortensen and Bethany Funke, were in the house during the attack and were not harmed. Mortensen texted Funke around 4:22 a.m. saying she had seen what appeared to be a masked man inside. The two locked themselves in a room and did not call 911 until nearly noon the next day, after going upstairs and finding their roommates.4ABC7 New York.

Between his junior and senior years of high school, Kohberger lost a dramatic amount of weight, reportedly dropping from over 300 pounds. The change was so stark that some classmates mistook him for a new student. Friends said he developed an eating disorder serious enough to require hospitalization, and that his personality became more aggressive during that period.5Idaho Statesman. Bryan Kohberger Background
He went on to Northampton Community College and then DeSales University, earning a bachelor’s in psychology and a master’s in criminal justice. One DeSales professor called him a “brilliant student” and said he was one of only two she had recommended for a doctoral program in a decade.7Inside Higher Ed.

In fall 2022, Kohberger enrolled as a first-semester doctoral student in criminology at Washington State University in Pullman, about ten miles from Moscow. He served as a teaching assistant and was terminated from that role in December 2022 for failing to meet professional behavior standards, after complaints that included concerns raised by female students.9CNN.

How Investigators Identified Him
The case initially stalled. No suspect was publicly named for weeks, and thousands of tips poured in to the FBI.2NBC News. Idaho College Student Killings Summary and Timeline Two threads of evidence eventually converged on Kohberger.
The first was the knife sheath left on a bed near one of the victims. It carried a single source of male DNA on its button snap. Idaho State Police sent the sheath to Othram, a private forensic laboratory in Texas, which developed a high-resolution profile using forensic-grade genome sequencing and uploaded it to public genetic genealogy databases. Within days, the lab produced a family tree pointing to the Kohberger family.10Forensic Magazine. Othram Worked on DNA That Led to Kohberger in University of Idaho Murders
The second was surveillance footage of a white Hyundai Elantra near the house around the time of the killings. Investigators sorted through more than 22,000 registered vehicles of that model before Washington State University police identified one registered to Kohberger.11WPBF. Idaho Murder Bryan Kohberger DNA Cell phone records then showed his phone had pinged towers near the King Road house at least 12 times before the murders, dating back to August 2022, usually late at night or in the early morning.

On December 27, 2022, investigators recovered trash from outside the Kohberger family home in Pennsylvania. Lab analysis found the male DNA in the trash was “99.9998% likely to be the biological father” of the person whose DNA was on the knife sheath.10Forensic Magazine.

What Is Known About Motive
No clear motive has ever been established. Kohberger offered no explanation at his plea or sentencing, and investigators found no social media connection or personal relationship between him and the victims. “He’s the only one that has the ‘why,'” Idaho State Police Lt. Darren Gilbertson said after the case concluded.12ABC News. Idaho Murders Investigators Speak on Targets, Motive, and Interviewing Kohberger
Lead prosecutor Bill Thompson said he believes Kohberger targeted one of the women on the third floor and likely did not expect to encounter Kernodle and Chapin awake on the second floor. Thompson also noted that Kohberger had attempted to “sanitize” his electronic devices by deleting information, which may have destroyed evidence that could have shed light on his reasons.12ABC News. Idaho Murders Investigators Speak on Targets, Motive, and Interviewing Kohberger Some speculation centered on the fact that two of the victims worked at a Moscow restaurant known for vegan options and that Kohberger had been a vegan for years, but no concrete link was ever established.
The Plea Deal and Sentence
Kohberger was extradited to Idaho on January 4, 2023. A grand jury indicted him on four counts of first-degree murder and one count of felony burglary in May 2023, and prosecutors announced the following month that they would seek the death penalty.2NBC News.

By June 2025, with trial set for August and almost every defense motion denied, the defense requested a plea offer.

He accepted four consecutive fixed life sentences without the possibility of parole, plus 10 years for burglary, and waived all rights to appeal.16Idaho Courts.
