Prosecutors Seek to Introduce Kohberger's Academic Paper and Balaclava Purchase in Idaho Murder Case

Court filings reveal prosecutors aim to use Bryan Kohberger's 2020 crime scene paper and a balaclava purchase as evidence linking him to the 2022 killings of four University of Idaho students.

Prosecutors disclosed that Bryan Kohberger purchased a black balaclava in January 2022, resembling a mask described by a surviving roommate who saw the intruder on the night of the murders.
A 12-page academic paper written by Kohberger in 2020, detailing crime scene procedures and evidence handling, is being introduced to demonstrate his knowledge of crime scenes.
Key evidence includes DNA found on a knife sheath at the crime scene and Kohberger’s purchase of a combat-style knife and sheath months before the murders.
The defense is challenging the admissibility of evidence and raising concerns about Kohberger’s developmental disabilities, including claims of autism spectrum disorder.
The trial, moved to Boise to ensure impartiality, is scheduled to begin on August 11, 2025, with jury selection starting in late July.
