Chilling photos reveal evidence that brought down Bryan Kohberger

Photos of the Ka-Bar knife sheath have been disclosed for the first time among more than 2,300 pages of evidence released by Idaho State Police. This sheath was a key item that linked Bryan Kohberger to the murder of four University of Idaho students.

Kohberger abandoned a brown leather Ka-Bar knife sheath at the crime scene shortly after fatally stabbing 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, left at 1122 King Road in Moscow, Idaho, to Kohberger, a 30-year-old criminology PhD student.

Details of the Evidence

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

"Photos have been revealed for the first time of the key piece of evidence that led to Bryan Kohberger being unmasked as the murderer of four University of Idaho students."
