Bryan Kohberger secretly alleges 24 flaws in Idaho murders indictment in latest motion to dismiss

Lawyers for the suspected Idaho student killer Bryan Kohberger aiming to dismiss the indictment against him are alleging grand jury bias, "inadmissible" and insufficient evidence and prosecutorial misconduct.

In a Wednesday filing, defense attorney Jay Logsdon revealed that Kohberger's team was raising 24 issues in support of the allegations – however, the memorandum including those details was filed under seal.

Prosecutors, whom Kohberger's team is accusing of withholding exculpatory evidence, have until Wednesday to respond, and a motion hearing is scheduled for September 1.

At a hearing on Friday, August 18, Kohberger's team sought to discredit DNA evidence in the case and called expert witnesses from across the country.

In a probable cause affidavit made public in January, prosecutors revealed key evidence used to obtain the initial warrant for Kohberger's arrest. A subsequent superseding indictment, however, presented evidence to grand jurors behind closed doors.

According to the affidavit, police responded to a house near the University of Idaho campus on November 13, 2022, and found four students dead: Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20 and Ethan Chapin, 20.

All four had been stabbed multiple times. Some were asleep at the start of the massacre. Investigators say there was a knife sheath with Kohberger's DNA on it under Mogen's body.

Kohberger, who attended the neighboring Washington State University in pursuit of a Ph.D. in criminology, drove a white Hyundai Elantra, the same type of car investigators identified as the suspect vehicle, and allegedly turned his phone off before heading to and from the crime scene, according to the affidavit.

Police, citing phone records, also alleged that he stalked the victims' home on a dozen occasions before the murders and drove by once more hours afterward.

Grand jurors could have been shown different or more in-depth evidence behind closed doors before agreeing to the indictment.

The judge entered not guilty pleas on Kohberger's behalf at his arraignment in May. Kohberger previously said, through a public defender where he was arrested in Pennsylvania, that he looked forward to being exonerated.

On Wednesday, he waived his right to a speedy trial, postponing proceedings that would have begun next month.
