Four University of Idaho students — Ethan Chapin, Xana Kernodle, Madison Mogen, and Kaylee Goncalves — were stabbed to death in their off-campus house in Moscow, Idaho. Bryan Kohberger, a criminology PhD student, was arrested in December 2022. The case drew enormous national media coverage. Bryan Kohberger pleaded guilty to all charges in July 2025 and was sentenced to life in prison without parole.

In the early morning hours of November 13, 2022, four University of Idaho students were fatally stabbed inside an off-campus rental house at 1122 King Road in Moscow, Idaho. The victims were Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20. According to authorities, the attacks occurred between roughly 4:00 and 4:25 a.m., carried out with a large fixed-blade knife. Two other roommates who were home survived unharmed. Investigators said one surviving roommate reported waking to noises and briefly seeing a masked man dressed in black leave the residence. A 911 call reporting an unconscious person was placed later that morning, and responding officers discovered the four victims.

The killings shocked the small college town and drew national attention. For nearly seven weeks no suspect was named and no weapon was recovered, fueling widespread community fear and prompting many students to leave Moscow. The FBI joined the Moscow Police Department and Idaho State Police, sifting through thousands of tips. Investigators publicly focused on a white Hyundai Elantra seen near the home and, in mid-December 2022, announced a review of tens of thousands of vehicle records to identify it.

The investigative breakthrough came from forensic evidence. According to court filings, a knife sheath left at the scene carried touch DNA, which authorities said was analyzed using investigative genetic genealogy to develop a lead. Prosecutors stated that DNA later recovered from Bryan Christopher Kohberger, then a 28-year-old criminology PhD student at Washington State University in Pullman, about eight miles from Moscow, matched DNA on the sheath. Kohberger was arrested on December 30, 2022, at his family's home in Monroe County, Pennsylvania, on four counts of first-degree murder and one count of burglary, and was extradited to Idaho in early January 2023.

A grand jury indicted Kohberger in May 2023, and prosecutors announced they would seek the death penalty. Kohberger stood silent at arraignment, and a not-guilty plea was entered on his behalf. Amid extensive pretrial litigation and publicity, the trial was moved from Latah County to Ada County (Boise), where Judge Steven Hippler presided. In a sudden resolution, Kohberger agreed to a plea deal and, on July 2, 2025, pleaded guilty to all four murders and the burglary charge, admitting responsibility and waiving his right to appeal in exchange for the state dropping its pursuit of capital punishment.

On July 23, 2025, Judge Hippler sentenced Kohberger to four consecutive terms of life in prison without the possibility of parole for the murders, plus the maximum 10 years for burglary. Victims' family members delivered impact statements at the hearing; Kohberger declined the opportunity to speak, and the judge noted that a definitive motive may never be publicly known. As of 2026, Kohberger is serving his life sentences in Idaho, and the case is legally closed following his conviction and sentencing.
