Idaho judge strikes blow to Brian Kohberger’s defence with DNA ruling

A judge has denied a high-profile quadruple murder suspect’s motions to suppress key evidence collected during search warrants, dealing his defence team a severe blow.

A judge has denied Idaho college murders suspect Bryan Kohberger’s motions to suppress key evidence collected during search warrants, dealing his defence team a severe, but expected blow.

Kohberger’s defence team brought up two DNA samples from unidentified males at the King Road home where he is accused of killing four University of Idaho undergrads, as part of their effort to have his arrest warrants thrown out, Fox News reports.

Two unidentified male blood samples, one on a handrail and one on a glove outside, were recovered by investigators after the stabbing deaths of Madison Mogen, 21; Kaylee Goncavles, 21; Xana Kernodle, 20; and Ethan Chapin, 20. Neither matched Kohberger, and they came from different subjects.

With the sources of both in question, defence lawyer Anne Taylor told Ada County Judge Steven Hippler at a hearing last month that it could mean Kohberger, 30, is not related to the crime at all.

But in the pre-trial stage, the judge seemed unconvinced that the presence of two other DNA samples would be a reason to throw out probable cause for Kohberger’s arrest. Detectives made another damning find — a Ka-Bar knife sheath under Mogen’s body.

“His DNA is still on the knife sheath, though,” Hippler told Taylor in court. “That’s the problem, counsel.”

Judge Hippler also denied Kohberger a Frank’s hearing, which would have allowed his attorneys to challenge how police conducted the investigation which resulted in Kohberger’s arrest in December 2022.

Kohberger was studying for a PhD in criminology and criminal justice at Washington State University at the time of the murders. The University of Idaho is only 16km away from WSU.

Kohberger is charged with murdering four University of Idaho students in their off-campus home in the early morning hours of November 13, 2022.

A nearly two-month investigation led police to finally nab Kohberger at his parents’ home in Pennsylvania.

Prior to the SWAT raid on the home, Kohberger and his dad were stopped twice by Indiana law enforcement on a cross-country drive home to Pennsylvania from his apartment in Pullman, Washington, about 16km from the crime scene.

Kohberger’s trial is scheduled to start in August. If convicted, Kohberger could face the death penalty.
