Newly released photographs reveal shocking evidence left by Brian Koberger after he killed four University of Idaho students in the early hours of November 13, 2022. Size 13 footprints in the snow outside his off-campus residence and a knife sheath were among the most telling signs of his actions that night.
The Daily Mail reported that these disturbing images were part of a significant file release by Idaho State Police, totaling around 3,000 files, which provided insight into the tragic events before they were quickly taken down.
One of the most critical pieces found at the crime scene was a tan leather knife sheath that matches a KA-BAR combat knife, identified as the weapon used in the stabbings of Zana Kernodle, Kaylee Gonsalves, Madison Mogen, and Ethan Chapin. The sheath was discovered on Mogen’s bed, surrounded by blood-stained sheets.
Forensic analysts matched DNA found on the sheath to Koberger. Investigators also noted that he had bought a set of knives months prior to the killings. Initial assumptions were that Koberger left the sheath behind to confuse the investigators. However, they later suggested he accidentally discarded it in a panic during the violent events.
While searching, investigators tracked footprints in the snow that led away from Koberger’s home. Crucially, a large footprint was also located at the crime scene after detectives applied a chemical agent to the floor. Notably, Nike shoes seized from Koberger’s home matched the size of these prints.
Koberger, who pleaded guilty to the murders in July, carried out the attacks around 4 a.m., completing the horrific spree in mere minutes. He reportedly entered through a sliding door and attacked the two young women brutally, leaving behind the DNA-laden sheath before moving upstairs to Mogen’s room, where he encountered Gonsalves.
Koberger subsequently attacked Kernodle, who had just returned from picking up a food delivery, before moving to kill Chapin, who was also asleep in the room.
Latest coverage on Brian Koberger
The graphic images released previously have been the most detailed depiction of the crime scene since the incident occurred. Idaho State Police have temporarily taken down the photo release, citing privacy concerns and the need for further review before any potential reposting.
A spokesperson for the department noted that many public record requests had followed the verdict in Koberger’s case, prompting the need to assess the appropriateness of the materials released.
In redacting the files, the Idaho State Police also complied with a judge’s injunction that required specific areas of photos showing blood near deceased individuals to be obscured. This decision was made to address privacy versus public transparency, amidst growing scrutiny.
As a graduate student at Washington State University in Pullman, Koberger received four life sentences without the possibility of parole at the Idaho Maximum Security Institute, avoiding the death penalty through a controversial plea deal.
