Chilling Photos Reveal Evidence That Brought Down Bryan Kohberger

Newly released images from the Idaho State Police show, for the first time, the Ka-Bar knife sheath that became the key evidence in identifying Bryan Kohberger as the killer of four University of Idaho students.

The Critical Evidence

Kohberger left behind a brown leather Ka-Bar knife sheath as he fled the crime scene in the early hours of November 13, 2022. The murders claimed the lives of Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin.

Forensic Breakthrough

Investigators used forensic genetic genealogy to match DNA found on the sheath to the 30-year-old criminology PhD student. This discovery was instrumental in his identification and arrest.

Details of the Sheath

The photos display a brown leather sheath engraved with a USMC military seal, measuring under 15 inches in length. It was part of over 2,300 pages of evidence disclosed by Idaho authorities.

Timeline and Purchase

Kohberger purchased the Ka-Bar knife and sheath on Amazon in March 2022, roughly eight months before the killings and three months before relocating from Albrightsville, Pennsylvania, to Pullman, Washington. The knife itself has not been recovered.

"The sheath left behind at 1122 King Road in Moscow, Idaho, contained the DNA that ultimately revealed the killer’s identity."
