BOISE, Idaho (AP) — A judge is expected to order Bryan Kohberger to serve four life sentences without parole this week for the brutal stabbing deaths of four University of Idaho students nearly three years ago.

Wednesday’s sentencing hearing will give 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.

Kohberger was a graduate student at Washington State University when he broke into a nearby rental home through a kitchen sliding door and killed the four friends who appeared to have no connection with him.

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.
