Background on the Knife and Sheath

Kohberger purchased the Ka-Bar knife and sheath from Amazon in March 2022, months before the murders. He moved from his parents’ home in Albrightsville, Pennsylvania, to Pullman, Washington, three months prior to the killings. The actual knife believed to be the murder weapon has not 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."
"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."

Release of Evidence

The newly disclosed photos are part of over 2,300 pages of evidence released by the Idaho State Police, shedding light on the investigation that led to Kohberger's arrest.
