Chilling Photos Reveal Key Evidence in Bryan Kohberger Case

Photos of the Ka-Bar knife sheath have been disclosed for the first time as part of over 2,300 pages of evidence released by the Idaho State Police. This sheath served as a crucial item that helped identify Bryan Kohberger as the murderer of four University of Idaho students.

The Knife Sheath's Role in the Investigation

Kohberger left behind a brown leather Ka-Bar knife sheath when he fled the crime scene shortly after the murders of Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin in the early hours of November 13, 2022. Forensic genetic genealogy matched DNA found on the sheath at 1122 King Road in Moscow, Idaho, to Kohberger, a 30-year-old criminology PhD student.

Details of the Sheath and Weapon

The sheath is brown leather, adorned with a USMC military seal, and is less than 15 inches long.
Kohberger purchased both the sheath and a Ka-Bar knife, believed to be the murder weapon, from Amazon in March 2022.
This purchase occurred eight months before the murders and three months prior to his relocation from his parents’ home in Albrightsville, Pennsylvania, to Pullman, Washington.
Importantly, the knife itself has never been recovered.

"It was this crucial piece of evidence that led to the killer’s downfall, as forensic genetic genealogy traced DNA on the sheath left behind at 1122 King Road in Moscow, Idaho, to the 30-year-old criminology PhD student."

These newly released images provide insight into the tangible evidence instrumental in the case against Kohberger.

Summary: The discovery and DNA analysis of a Ka-Bar knife sheath left at the crime scene was pivotal in identifying Bryan Kohberger as the murderer of four students, despite the murder weapon remaining missing.
