BOISE, Idaho (AP) — Bryan Kohberger has been sentenced to life in prison without parole in the brutal stabbing deaths of four University of Idaho students nearly three years ago.

Judge Steven Hippler ordered Kohberger to serve four life sentences, one for each murdered student, which will run consecutively. The defendant pleaded guilty early this month, just weeks before his trial was to start, in a deal to avoid the death penalty.

Wednesday’s sentencing hearing gave the families of Xana Kernodle, Madison Mogen, Ethan Chapin and Kaylee Goncalves the opportunity to describe the anguish they’ve felt since their loved ones were killed in the early morning hours of Nov. 13, 2022.

“This world was a better place with her in it,” Scott Laramie, the stepfather of Madison Mogen, told the court. ”Karen and I are ordinary people, but we lived extraordinary lives because we had Maddie.”

A roommate who survived the attack, Bethany Funke, provided a statement that a friend read on her behalf in the courtroom. She described the day her four friends died as “the worst day of my life, and I know it always will be.”

“I slept in my parents’ room for almost a year, and had them double lock every door, set an alarm, and still check everywhere in the room just in case someone was hiding,” Funke wrote. “I have not slept through a single night since this happened. I constantly wake up in panic, terrified someone is breaking in or someone is here to hurt me, or I’m about to lose someone else that I love.”

The father of Kaylee Goncalves taunted Kohberger for leaving his DNA behind and getting caught despite being a graduate student in criminology at nearby Washington State University at the time.

“You were that careless, that foolish, that stupid,” Steve Goncalves said. “Master’s degree? You’re a joke.”

Kohberger broke into the home through a kitchen sliding door and brutally stabbed the four friends, who appeared to have no connection with him. No motive has been offered, and Kohberger chose not to speak at the hearing.

He remained expressionless as the testimony went on, and chose not to speak before his sentencing.

Dylan Mortenson, a roommate who told police of seeing a strange man with bushy eyebrows and a ski mask in the home that night, sobbed as she described how Kohberger, seated across the room in an orange jumpsuit, “took the light they carried into each room.”

“He is a hollow vessel, something less than human,” Mortenson said. “A body without empathy, without remorse.”

Police initially had no suspects, and the killings terrified the normally quiet community in the small, western Idaho city of Moscow. Some students at both universities left mid-semester, taking the rest of their classes online because they felt unsafe.

But investigators had a few critical clues. A knife sheath left near Mogen’s body had a single source of male DNA on the button snap, and surveillance videos showed a white Hyundai Elantra near the rental home around the time of the murders.

Police used genetic genealogy to identify Kohberger as a possible suspect, and accessed cellphone data to pinpoint his movements the night of the killings. Online shopping records showed Kohberger had purchased a military-style knife months earlier, along with a sheath like the one at the home.

Kohberger was arrested in Pennsylvania about six weeks after the killings. He initially stood silent when asked to enter a plea, so a judge entered a “not guilty” plea on his behalf.

Both the investigation and the court case drew widespread attention. Discussion groups proliferated online, members eagerly sharing their theories and questions about the case. Some self-styled armchair web-sleuths pointed fingers at innocent people simply because they knew the victims or lived in the same town. Misinformation spread, piling additional distress on the already-traumatized community.

As the criminal case unfolded, Latah County Prosecutor Bill Thompson announced that he would seek the death penalty if Kohberger was convicted. The court-defense team, led by attorney Anne Taylor, challenged the validity of the DNA evidence, unsuccessfully pushed to get theories about possible “alternate perpetrators” admitted in court, and repeatedly asked the judge to take the death penalty off of the table.

But those efforts largely failed, and the evidence against Kohberger was strong. With an August trial looming, Kohberger reached a plea deal. Prosecutors agreed to drop their efforts to get a death sentence in exchange for Kohberger’s guilty plea to four counts of first-degree murder and one count of burglary. Both sides agreed to a proposed sentence of four consecutive life sentences without parole, plus an additional 10 years for the burglary charge. Kohberger also waived his right to appeal any issues in the case.

Kohberger’s mother and sister also attended the hearing, sitting in the gallery near the defense table. His mother quietly wept at times as the other parents described their grief. She sobbed briefly when Maddie Mogen’s grandmother said that her heart goes out to the other families, including Kohberger’s.

Xana Kernodle’s aunt, Kim Kernodle, said she forgave Kohberger and asked him to call her from prison, hoping he would answer her lingering questions about the killings.

“Bryan, I’m here today to tell you I have forgiven you, because I no longer could live with that hate in my heart,” she said. “And for me to become a better person, I have forgiven you. And any time you want to talk and tell me what happened, get my number. I’m here. No judgment.”
