Idaho Prosecutors Seek to Limit Defense Strategies in Bryan Kohberger Murder Trial

Prosecutors aim to block alternative perpetrator claims and restrict alibi and psychiatric evidence as trial approaches in August.

Bryan Kohberger is accused of fatally stabbing four University of Idaho students in November 2022 and faces the death penalty if convicted.
Prosecutors have requested the judge to bar the defense from presenting alternative perpetrator theories without proving their relevance under Idaho's evidence rules.
Key DNA evidence linking Kohberger to the crime scene, including a knife sheath with his DNA, will be allowed at trial despite defense challenges to its admissibility.
The defense's attempt to suppress investigative genetic genealogy evidence was denied, with the court ruling it did not violate Kohberger's constitutional rights.
The trial, set to begin on August 11, will also feature a 3D FBI model of the crime scene, created to aid witness testimony after the house's demolition.
