2022 University of Idaho murders

In the early morning hours of November 13, 2022, four University of Idaho students—Madison Mogen, Kaylee Goncalves, Ethan Chapin, and Xana Kernodle—were fatally stabbed in an off-campus house in Moscow, Idaho. On December 30, authorities arrested 28-year-old Bryan Christopher Kohberger in Monroe County, Pennsylvania, on four counts of first-degree murder and one count of felony burglary. At the time of the murders, Kohberger was a PhD student completing his first semester at Washington State University in Pullman, Washington, located less than eight miles (13 km) west of Moscow.

Prosecutors initially sought the death penalty. On July 2, 2025, Kohberger entered a guilty plea to all charges against him as part of a deal to avoid the death penalty. Three weeks later, he was sentenced to four consecutive life sentences in prison without the possibility of parole, plus ten years for burglary.

Lives and background

During the fall 2022 semester, five female University of Idaho students lived in a rented off-campus residence in the rural college town of Moscow, Idaho. The town of Moscow had not had a murder since 2015. The three-story house had six bedrooms, two on each floor. Built on a hillside, the house had entrances on both the first and second floors.

Kaylee Goncalves and Madison Mogen had their bedrooms on the third floor. On the night of the murders, Mogen and Goncalves slept in Mogen's room. The second floor had the house's kitchen and the bedrooms of Xana Kernodle and surviving roommate Dylan Mortensen. At that time, Kernodle's boyfriend, Ethan Chapin, was staying at the house in her room. The first floor of the house had the bedroom of another surviving roommate, Bethany Funke.

Mogen and Goncalves both grew up in Coeur d'Alene, Idaho, and had been best friends since childhood. Mogen, age 21, was a senior majoring in marketing. She was a member of the Pi Beta Phi sorority and had a part-time job working at the Mad Greek restaurant in Moscow. Twenty-one-year-old Goncalves was a senior majoring in general studies and a member of the Alpha Phi sorority. She was set to graduate the following month, finishing her studies a semester early. She had already lined up a job with an IT firm in Texas and was planning to move shortly after graduating.

Kernodle, age 20, grew up in Avondale, Arizona, and later lived in Post Falls, Idaho. She was a junior majoring in marketing. Like Mogen, she was a member of the Pi Beta Phi sorority and had a part-time job working at the Mad Greek restaurant in Moscow. Chapin, age 20, grew up in Mount Vernon, Washington, and was a triplet close to his siblings and parents. He was a sophomore majoring in recreation, sport and tourism management. Chapin was a member of the Sigma Chi fraternity.

Murders

All five roommates and Chapin were in the house by 2:00 a.m. on November 13, 2022. Chapin and Kernodle had returned from an on-campus party at the nearby Sigma Chi fraternity, arriving home at 1:45 a.m. Mogen and Goncalves had gone to a downtown sports bar called Corner Club and then a food truck called Grub Truck, arriving home at 1:56 a.m. Between 2:26 to 2:52 a.m., the phones of Goncalves and Mogen made several unanswered calls to the former long-time boyfriend of Goncalves, a fellow student.

Detectives believe all four murders occurred between 4:00 and 4:25 a.m. Kernodle appears to have been awake when the killer entered the house, as she had just received a DoorDash food order at around 4:00 a.m, and was using the TikTok app on her phone at 4:12 a.m. Surviving roommate Dylan Mortensen, who was asleep in her bedroom on the second floor, told investigators that she was awakened by a noise on the third floor that she initially thought was Goncalves and her pet dog. She stated she later heard someone saying something to the effect of "there's someone here." Mortensen believed this was Goncalves, although investigators believe it may have been Kernodle.

Mortensen looked out her door but did not see anything. She stated she then heard what sounded like crying from Kernodle's room. She opened her door again and heard an unfamiliar male voice say, "It's okay; I'm going to help you." Security cameras near the house picked up the sound of whimpering, a loud thud, and a dog barking numerous times starting around 4:17 a.m. Mortensen opened her door a third time and saw a figure clad in black clothing and a mask that covered his mouth and nose walking towards her. The man, whom Mortensen stated she did not recognize, walked past her and exited through a sliding glass door in the kitchen. Mortensen stated she stood in a "frozen shock phase" and then locked herself in her room. She later told authorities she did not immediately call 911 after seeing a masked stranger in the house because she "was intoxicated and didn't want to believe what was going on."

At approximately 4:26 a.m., Mortensen went downstairs to join the other surviving roommate, Bethany Funke. On the way, Mortensen saw Kernodle lying on the floor of her bedroom. She later told police that she believed at the time Kernodle may have been intoxicated.

The two surviving roommates then locked themselves in Funke's bedroom and spent several hours attempting to contact their other housemates. The following morning they still had not heard anything from the other housemates, and Mortensen called friends over for help. Soon after arriving, one of the friends went to the second floor where he discovered that Chapin and Kernodle had no pulses. He told the others to exit the home, and Funke called 911 at 11:55:42 a.m., requesting aid for an "unconscious person."

All four victims were pronounced dead at the home that afternoon. Kernodle and Chapin were discovered in her second floor bedroom, with Kernodle lying on the floor and Chapin in bed. Mogen and Goncalves were found in the single bed in Mogen's room on the third floor. All four were stabbed to death. The victims were not gagged or restrained and none had been sexually assaulted. Goncalves had more than twenty stab wounds in addition to injuries "connected with asphyxiation and blunt force trauma." Kernodle had more than fifty stab wounds, many of them defensive wounds. Upon searching the residence, officers discovered Goncalves' dog — which she shared with her ex-boyfriend — unharmed on the third floor.

Response

On the evening of November 13, the university canceled classes for November 14; it also scheduled a candlelight vigil on the UI administration building lawn on the evening of November 16, then postponed it for two weeks. From the day of the killings, investigators initially said that there was no risk to the community. Three days later, however, Moscow Police Chief James Fry said: "We cannot say that there is no threat to the community."

Fall break was scheduled to begin after November 18, with classes resuming on November 28. Many students and Moscow residents, not trusting initial police assurances and fearing for their safety, began an early Thanksgiving holiday exodus from the area. Other residents who stayed were anxious and cautious, and some professors canceled their classes. Due to weather concerns, the candlelight vigil was moved indoors to the Kibbie Dome and held on the evening of November 30.

The fathers of Goncalves and Chapin criticized the limited flow of information from police and the university to the victims' families. TikTokers, self-proclaimed psychics, and social media users began to speculate and spread rumors and misinformation about the case on social media. In response, the Moscow Police Department criticized the Internet sleuths for creating rampant online rumors and disrupting investigations, and in a December 2 news release stated: "There is speculation, without factual backing, stoking community fears and spreading false facts." Moscow Police Captain Roger Lanier said, "Tracking down rumors and quelling rumors about specific information and specific events that may not have happened is a huge distraction... We are not releasing specific details as we do not want to compromise the investigation." They also warned that "people harassing or threatening those potentially involved with the case could face criminal charges."

Investigation

The Moscow Police Department (MPD) led the investigation of the stabbings with support from the Idaho State Police (ISP) and the Federal Bureau of Investigation (FBI). Nearly 130 law enforcement personnel worked on the case.

On November 19, Moscow police requested the public provide any video of the house that was recorded the night of the killings. A phone tip line and email address were created through the FBI for the public to submit information to officials. As of December 5, 2,600 emailed tips, 2,700 phone calls, and 1,000 digital media submissions were reportedly submitted to the tip lines. On December 24, investigators reported receiving over 15,000 tips regarding the case.

The police initially left open the possibility of multiple perpetrators. Police stated that they believed it was "a targeted attack but have not concluded if the target was the residence or its occupants."

In a November 23 press conference, the Moscow police chief said that authorities received a number of tips, including one indicating that Goncalves had a stalker, but could not verify that claim or identify any such individual by the time of the press conference. While this claim received much press attention at the time, it has yet to be mentioned in the case against the eventual suspect.
