The latest pre-trial developments in the case of Idaho quadruple murder suspect Bryan Kohberger

The defense team of Bryan Kohberger, the man accused of killing four University of Idaho students in their off-campus home in 2022, has requested to move the case out of town, saying in a recent memorandum he can’t receive a fair trial in Latah County because of “inflammatory” publicity.

But prosecutors have rejected that argument, saying the court could put in place other measures to ensure a fair trial. The defense then reiterated its plea to change the venue, with survey results showing the county’s “mob mentality.”

The filings are the latest pre-trial developments in Kohberger’s quadruple murder trial, which is set to begin in June 2025.

It’s been a long and winding road since the four students – Kaylee Goncalves, Ethan Chapin, Xana Kernodle and Madison Mogen – were fatally stabbed in the overnight hours of November 13, 2022, at a home just off the school’s main campus in Moscow, Idaho.

Kohberger, a Washington State University graduate student in criminology, was arrested in the killings on December 30, 2022, in his home state of Pennsylvania. A not guilty plea was entered on his behalf in May 2023, and his attorneys have indicated the 29-year-old intends to present an alibi as part of his defense. Prosecutors have said they will seek the death penalty.

The progression of the case has been slowed by a series of pre-trial motions and hearings that have frustrated the family of one of the victims as well as the judge overseeing the case.

The hearings largely fall into a few different buckets. One relates to the defense attorneys’ access to evidence, particularly how the prosecution used investigative genetic genealogy in building the case. A second set of hearings concerns Kohberger’s proposed alibi for his innocence. Third, there have be a number of hearings related to a gag order that restricts what the parties can publicly say about the case.

Here’s a timeline of some of the notable pre-trial developments and decisions so far:

June 9, 2023: A coalition of media organizations and the family of a murder victim came to court to challenge the gag order placed on the parties in the case.

June 23, 2023: Latah County Judge John Judge denied both requests but issued a revised gag order that allows the parties to discuss topics that do not have a “substantial likelihood of materially prejudicing or otherwise influencing the outcome of the case.”

August 2, 2023: Kohberger’s attorneys said they would use an alibi defense but couldn’t pin down their client’s specific location on the night of the killings because he was “driving during the late night and early morning hours.”

“Mr. Kohberger is not claiming to be at a specific location at a specific time; at this time there is not a specific witness to say precisely where Mr. Kohberger was at each moment of the hours” of the attacks, his attorneys said in a court filing.

October 26, 2023: The judge denied a request to dismiss the grand jury indictment after the defense argued there was an error in the grand jury instructions.

December 18, 2023: The judge denied a second motion to dismiss the indictment after the defense argued prosecutors failed to comply fully with state rules on jury selection and the jury questionnaire.

February 28, 2024: Defense attorney Anne C. Taylor asked the court to allow three defense experts and others to view the investigative genetic genealogy evidence, which has been sealed, to understand the full timeline of how police began to focus on Kohberger.

Genetic genealogy is a practice that blends DNA analysis in the lab with genealogical research, such as tracing a person’s family tree. In this case, investigators found a single source of male DNA on the button snap of a leather knife sheath left at the crime scene, according to a probable cause affidavit. FBI investigators loaded the DNA profile to public genealogy sites to search for a match and then sent a tip to investigate Kohberger, according to a prosecution court filing.

The judge initially declined to give the defense investigators extended access to the investigative genetic genealogy, saying he would rather the experts already approved to view the material give justification for digging deeper.

April 4, 2024: The judge criticized Kohberger’s defense attorney, saying she commissioned phone surveys to potential jurors that could hinder Kohberger’s ability to get a fair trial. However, Taylor said the judge violated her client’s right to due process by ordering a stop to the anonymous survey without hearing the defense’s side first.

Judge said in April he wants a “hearing at least every month,” noting the importance of “cleaning up” the legal proceedings.

April 17, 2024: Kohberger’s defense lawyers filed a court document saying they plan to offer a cell phone tower and radio frequency expert to partially corroborate his proposed alibi that he was out driving west of Moscow on the night of the slayings.

April 19, 2024: The judge allowed surveys conducted with potential jurors to continue “without modification” after temporarily pausing them.

April 29, 2024: The prosecution asked the court to deny Kohberger the opportunity to add to his alibi and to preclude anyone other than the defendant to testify as to his whereabouts on the night of the murders.

May 2, 2024: Kohberger’s defense had asked for an upcoming evidentiary hearing with witnesses be made public, while the prosecution asked that it be sealed. The judge ruled that it will be closed to the public.

After the hearing, the family of Goncalves, one of the victims, criticized the slow pace of the proceedings. “This case is turning into a hamster wheel of motions, hearings, and delayed decisions,” adding they were “incredibly frustrated.”

May 23, 2024: Taylor, the defense attorney, questioned a Moscow police detective about the preparation of visual cell phone logs and methods for searching for certain videos. The testimony was related to two motions to compel prosecutors to share discovery with the defense, but the contents of the motions are sealed, so it was not clear what they were requesting.

May 30, 2024: The Moscow police detective leading the investigation and a defense expert in cell phone location data testified that the defense has not received some key evidence in the case.

Cpl. Brett Payne, the lead investigator on the case, testified he and other investigators collected thousands of hours of video surveillance as they tried to locate a white Hyundai Elantra connected to the suspect. The videos are saved on various thumb drives, but there is no central inventory of the videos, he testified. He also said investigators did not see on any of the videos the Elantra going south from Moscow toward Pullman, Washington, in the early morning hours after the killings.

The probable cause affidavit used in the case alleges Kohberger drove south toward Pullman after he committed the four killings.

Sy Ray, an expert on cell phone geolocation data, testified that he has not been provided the underlying AT&T source data and list of nearby cell towers that was used by detectives to create a map of Kohberger’s movements with his cell phone. Based on the data he had received, he believed some statements in the records were not accurate, and he said the missing data could be helpful to the defense.

“Because of the piecemealing of the data, because of the missing data, because of data that I’m reviewing that is incredibly inaccurate, everything that is missing is absolutely to the benefit of the defense right now,” he said.

June 7, 2024: After previously restricting who had access to the investigative genetic genealogy evidence, the judge ruled to allow unnamed “defense investigators” to view the material.

June 27, 2024: The parties set a trial date of June 2, 2025. Judge set aside about three months for the trial, including two weeks for jury selection, eight weeks for the trial and two weeks for potential post-conviction hearings and sentencing.

“This is a great step to set these deadlines and hearings so that we can move through this,” he said.

July 22, 2024: Kohberger’s defense team filed a memorandum in support of moving the case out of Latah County, saying he can’t receive a fair trial there “because of the extensive publicity that is ongoing and inflammatory.” The defense suggested the trial be moved to Ada County, which includes Boise, about 300 miles south. A hearing to discuss the change of venue is set for August 29.

August 13, 2024: Prosecutors objected to the defense team’s change of venue motion, arguing the defense failed to prove that Kohberger would not receive a fair trial in the county. “The Court should deny Defendant’s motion and instead, focus on crafting remedial measures to ensure that a fair and impartial jury can be seated in Latah County,” the prosecution argued.

August 19, 2024: In a reply to the state’s objection, Kohberger’s defense said moving the venue to Ada County is supported by expert analysis, precedent and results of a survey in Latah County showing a “mob mentality.” “The traumatized town of Moscow is understandably filled with deeply held prejudgment opinions of guilt,” the defense wrote.
