Chilling Photos Reveal Key Evidence Against Bryan Kohberger

Photos of the Ka-Bar knife sheath, a critical piece of evidence in the case against Bryan Kohberger, have been made public for the first time. The images come from over 2,300 pages of evidence released by the Idaho State Police.

Details of the Knife Sheath

The brown leather sheath, measuring less than 15 inches, bears a USMC military seal. It was left behind by Kohberger at the crime scene shortly after he fatally stabbed four University of Idaho students on November 13, 2022.

Role in Identifying the Suspect

Forensic genetic genealogy matched DNA found on the sheath at 1122 King Road in Moscow, Idaho, directly to Bryan Kohberger, a 30-year-old criminology PhD student. This discovery was pivotal in uncovering the identity of the murderer.

Background on the Weapon

Kohberger purchased the Ka-Bar knife and the sheath from Amazon in March 2022.
This was eight months before the murders and three months before he relocated from Pennsylvania to Washington.
The knife itself, believed to be the murder weapon, 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."

These discoveries underscore how seemingly small pieces of evidence can be crucial in solving complex criminal cases.
