Bryan Kohberger's defense challenges DNA evidence, warrants in ID quadruple murder case
2 years since University of Idaho murders
The University of Idaho hosted a special vigil Wednesday to mark the two year anniversary of the deaths of four students.
Attorneys for Bryan Kohberger, the man accused in the brutal stabbing deaths of four University of Idaho students, are challenging an array of evidence in an effort to prevent prosecutors from presenting it at trial.
A filing posted Friday totaled more than 160 pages and included the legal justification for blocking a variety of materials that Kohberger's lawyers say were improperly obtained, the Idaho Statesman reported.
Some of the evidence defense lawyers want suppressed is Kohberger's genetic information, which they argue was "illegally gathered by law enforcement," citing the Fourth Amendment, which protects against unreasonable searches and seizures, according to the newspaper.

Kohberger is accused of killing Madison Mogen, 21; Kaylee Goncalves, 21; Xana Kernodle, 20; and Ethan Chapin, 20, in a 4 a.m. attack on Nov. 13, 2022. All four were staying in a six-bedroom home just steps from the university campus.
At the time of the slayings, Kohberger was studying for a Ph.D. in criminology at neighboring Washington State University, less than 10 miles from the site of the killings.
He claimed he was taking one of many solo, nighttime drives at the time of the murders.
Authorities said Kohberger's DNA was found on a Ka-Bar knife sheath under Mogen's body. DNA was later matched to Kohberger through a cheek swab.
Other evidence being challenged by the defense includes the contents of Kohberger’s digital history on his Amazon, Google, Apple iCloud and AT&T phone accounts, citing privacy law violations, as well as evidence obtained from his apartment in Pullman, Washington, with a search warrant.
Prosecutors have until Dec. 6 to respond to the defense’s 14 evidence suppression filings. A public hearing on the matter is scheduled for Jan. 23.
Kohberger's attorneys fight to remove death penalty
Murder suspect Bryan Kohberger returned to court Thursday, where his defense hopes to have the death penalty taken off the table before he goes to trial in the stabbing deaths of four University of Idaho undergrads.
The venue for the murder trial was moved from the college town of Moscow to Boise after defense lawyers argued the extensive media coverage would make it difficult to find impartial jurors.
The change also resulted in Judge Steven Hippler being assigned to preside over the proceedings, replacing Latah County District Judge John Judge, who agreed to the change of venue.
Hippler, who is no stranger to murder cases, denied Kohberger's request to extend deadlines for filing motions for discovery material.

Bryan Kohberger defense calls in expert who helped O.J. Simpson get exonerated
As part of his defense team's effort to have the death penalty taken off the table before his trial in the killing of four University of Idaho students, lawyers for suspect Bryan Kohberger want to bring in a forensics expert with a record of taking a new look at old cases that had previously been considered solved.
"Motions to enlarge a deadline filed on the eve of the deadline are not well taken," the judge wrote in a Friday ruling. "The State's discovery deadline was September 6, 2024. Defendant could have ascertained far sooner whether the discovery motions deadline would pose a difficulty and brought it to the Court's attention."
"Furthermore, and importantly, Defendant has not demonstrated with his filing good cause to enlarge the deadline," he added. "He has not set forth what efforts have been made to review the discovery, what portion of discovery has not yet been reviewed, why it has not been reviewed or how long it will take to complete such review."
