The four University of Idaho students stabbed to death in November 2022 each sustained wounds consistent with prolonged suffering, newly unsealed autopsy reports reveal, offering the most detailed public account yet of how Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin died inside a rental home on King Road in Moscow, Idaho.
Bryan Kohberger, the former Washington State University criminology doctoral student charged with four counts of first-degree murder, has pleaded not guilty. His federal trial is set to begin August 11 in Boise after a change of venue moved the case out of Latah County. The autopsy findings, sealed for more than two years, now form a critical piece of the evidentiary record prosecutors intend to present to jurors.
Latah County Coroner Cathy Mabbutt conducted the four autopsies. Each victim's cause of death was listed as homicide by stabbing, Fox News reported. The reports describe multiple stab and incised wounds on every victim, with injuries to major organs and blood vessels.
Kaylee Goncalves, 21, sustained wounds to her torso, including injuries that perforated her lungs and liver. The autopsy noted defensive wounds on her hands and arms, indicating she fought back against her attacker. Goncalves had the highest number of individual stab wounds among the four victims.
Madison Mogen, 21, who shared a bed with Goncalves on the third floor of the home, suffered stab wounds to her upper body. Her injuries also included defensive wounds on her hands. The coroner noted that some of her wounds penetrated deeply enough to reach her chest cavity.
Xana Kernodle, 20, sustained stab wounds to her torso and extremities. Her autopsy documented injuries consistent with an active struggle, including bruising and defensive wounds. Kernodle and her boyfriend Ethan Chapin were on the second floor of the home at the time of the attack.
Ethan Chapin, 20, suffered multiple stab wounds to his chest and abdomen. The autopsy described wounds that damaged major blood vessels. Chapin's injuries, like the others, were consistent with a sustained assault rather than a single fatal blow.
Prosecutors have pointed to the autopsy findings as evidence that the victims "endured a high degree of pain" before dying. That language carries legal weight. In Idaho, prosecutors can seek the death penalty when a murder involves "exceptional depravity," which can include inflicting prolonged suffering on victims. The state initially pursued a death sentence against Kohberger before the case was moved to federal jurisdiction.
Federal prosecutors have not publicly stated whether they will seek the death penalty at the August trial. The Department of Justice must authorize a capital prosecution in federal cases, and that decision has not been announced. The autopsy evidence, however, gives prosecutors a factual foundation to argue the killings were carried out with particular brutality.
The unsealing of these reports comes after months of legal battles over sealed evidence in the case. An Idaho judge previously launched a criminal investigation into leaked sealed evidence from the Kohberger proceedings, underscoring how tightly courts have tried to control the flow of information in this case.
The presence of defensive wounds on multiple victims stands out in the autopsy reports. Defensive wounds typically appear on the hands, forearms, and arms when a person raises them to block or deflect an attack. The coroner documented such injuries on at least Goncalves, Mogen, and Kernodle.
Those findings suggest the victims were conscious and aware during portions of the attack. They also indicate the assailant faced physical resistance, a detail that could bear on how prosecutors reconstruct the sequence and duration of the killings for the jury.
Forensic pathologists consulted in similar cases have noted that the number and distribution of defensive wounds can help establish whether victims had time to react, which in turn speaks to how long the attack lasted. Prosecutors will likely use this evidence to argue the victims did not die quickly.
The four students were killed in the early morning hours of November 13, 2022, inside a six-bedroom rental home near the University of Idaho campus. Two other roommates who were on the first floor survived and were unharmed. One of the surviving roommates called 911 later that morning after discovering something was wrong, though the precise timeline of events inside the home remains a subject the defense has challenged.
Investigators identified Kohberger as a suspect through DNA evidence and cellphone data. A knife sheath found near one of the victims contained DNA that investigators matched to Kohberger through genetic genealogy, then confirmed with a direct sample. Cellphone records placed Kohberger's phone near the King Road residence in the hours surrounding the killings, and surveillance footage captured a white Hyundai Elantra consistent with his vehicle in the area.
In other high-profile murder cases, forensic DNA evidence has proven both powerful and contested, and the Kohberger defense has signaled it intends to challenge the DNA analysis and collection methods used here.
Kohberger's defense team, led by public defender Anne Taylor, has maintained his innocence and has aggressively challenged the prosecution's evidence at every stage. The defense has questioned the reliability of cellphone location data, the handling of DNA evidence, and the investigative procedures used by the Moscow Police Department and the FBI.
Taylor's team has also fought to suppress certain evidence and has raised concerns about pretrial publicity tainting the jury pool, which contributed to the change of venue from Moscow to Boise. The defense has not yet publicly responded to the specific autopsy findings in the unsealed reports.
The defense team has been vocal about what it considers improper public commentary on the case. Kohberger's attorneys previously declared themselves "appalled" after a former defense expert went public with statements about the case, arguing that such disclosures threatened their client's right to a fair trial.
Meanwhile, Kohberger's family has maintained his innocence from the beginning. His mother told the FBI after his arrest that he was "my angel" and insisted law enforcement had made a serious mistake.
The case moved to federal jurisdiction after prosecutors determined the crimes could be charged under federal statutes. The trial is scheduled to begin August 11 at the federal courthouse in Boise. Judge Scott Bluestein is presiding.
Jury selection is expected to be a lengthy process given the extensive media coverage the case has received. Prospective jurors will be drawn from the District of Idaho. Both sides have indicated they expect the trial to last several weeks, given the volume of forensic evidence, witness testimony, and expert analysis involved.
The unsealed autopsy reports will likely be entered as exhibits during the prosecution's case-in-chief. Prosecutors may call the coroner and additional forensic pathologists to walk jurors through the findings and explain the medical significance of each wound pattern.
Authorities have not publicly confirmed the precise order in which the four victims were attacked. The sequence matters because it could affect how prosecutors argue premeditation and whether the jury concludes the killer moved deliberately from room to room.
Investigators have also not said publicly whether any of the victims were awake before the attack began or whether they were roused by the assault itself. The defensive wounds suggest awareness, but the autopsy reports alone cannot establish the full timeline of consciousness for each victim.
The murder weapon has not been recovered. Prosecutors have described it as a large fixed-blade knife consistent with a Ka-Bar-style blade, based on wound characteristics and the sheath left at the scene. Investigators will need to explain to jurors how they reached conclusions about the weapon without presenting it physically.
Moscow, Idaho, a college town of roughly 26,000, has lived under the shadow of these killings for more than two and a half years. The King Road house where the murders occurred was demolished in December 2023 at the university's direction, a decision that drew mixed reactions from the victims' families and the broader community.
The families of all four victims have largely avoided public statements since the early months of the case, though some have expressed frustration with the pace of proceedings. The unsealing of the autopsy reports, while painful, provides a measure of the transparency families and the public have sought since the beginning.
Four young people fought for their lives in the dark, and the evidence of that fight is now part of the public record. When the trial begins in August, jurors will have to look at every wound, every mark of resistance, and decide whether the man sitting at the defense table put them there.
