Prosecutors Seek to Introduce Kohberger's Crime Scene Essay and Balaclava Purchase as Key Evidence

New filings highlight Bryan Kohberger's academic paper on crime scenes and his purchase of a balaclava similar to the mask described by an eyewitness.

Prosecutors plan to use a 2020 academic paper written by Bryan Kohberger to demonstrate his detailed knowledge of crime scene procedures and evidence handling.
Kohberger's paper outlines steps to avoid crime scene contamination, which prosecutors argue aligns with the lack of forensic evidence left at the Idaho murder site.
Court filings reveal Kohberger purchased a black balaclava in January 2022, closely resembling the mask described by a surviving roommate who saw the intruder.
Defense attorneys challenge the admissibility of this evidence and argue that Kohberger's developmental disabilities, including autism spectrum disorder, may undermine the prosecution's claims.
The trial, relocated to Boise for impartiality, is set to begin on August 11, 2025, with pretrial hearings scheduled for April 9.
