Former criminology graduate student Bryan Kohberger was struggling to understand the court proceedings against him just weeks before he pleaded guilty to murdering four students.
Newly unsealed court documents reveal that his former defense team raised serious concerns about whether the 31-year-old could rationally understand his case and make "consequential decisions" about his defense.
Kohberger is currently serving four consecutive life sentences without the possibility of parole. He pleaded guilty in July 2025 to killing University of Idaho students Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin.
The new revelations emerged on Tuesday when Judge Steven Hippler ordered a previously sealed legal memorandum to be made public. The document was filed by Kohberger's new attorney, Greg Rauch, as part of an ongoing effort to withdraw the guilty plea and challenge the conviction.
The victims were murdered on November 13, 2022, inside an off-campus rental apartment at 1122 King Road in Moscow, Idaho. Moscow is a small college town in the state's northern panhandle region.
A selfie taken by Kohberger hours after the murders has since circulated widely. Investigators also recovered a brown leather Ka-Bar knife sheath that was left behind at the crime scene.
Kohberger was a student at neighboring Washington State University, which is located a short distance away in Pullman, Washington. He was arrested on December 30, 2022, and charged with four counts of first-degree murder alongside one count of burglary.
"The memo is pretty clear that there's a serious issue there that shows different reasons why that plea might not have been accepted," Rauch told Fox News Digital following the unsealing of the document.
"Those issues have to be fleshed out and explored."
Struggles in court
According to the Tuesday filing, the former defense team led by Anne Taylor approached the court on May 20, 2025. They advised the court that their client was having difficulty understanding adverse rulings from the bench.
"Counsel advised the Court that Kohberger was having difficulty comprehending adverse rulings and discerning their effect upon the case as a whole," the newly published memorandum reads.
Taylor and her team sought additional time and expert assistance. They stated that they needed to investigate his ability to understand the legal proceedings and make informed choices regarding his defense strategy.
At the time, the legal proceedings were moving rapidly toward what was expected to be a high-profile murder trial. For more than two years, Kohberger had firmly maintained his innocence.
His lawyers had aggressively challenged the evidence presented by the prosecution and fought over issues including the potential application of the death penalty. First-degree murder charges in Idaho can carry capital punishment, which made the stakes of the trial particularly high.
The defense requested a delay to evaluate his mental competency. However, on Thursday, June 26, 2025, Judge Hippler denied the request for additional time.
The court concluded that Kohberger had not demonstrated good cause for a continuance, nor had he shown that proceeding toward the scheduled trial date would cause him prejudice.
The guilty plea
Just six days after the judge denied the request for more time, Kohberger abandoned the trial altogether. On Wednesday, July 2, 2025, he appeared in a courtroom in Boise, Idaho, and pleaded guilty to each of the four murders and the burglary charge.
During that plea hearing, Judge Hippler repeatedly questioned the defendant to establish that he understood exactly what he was doing.
"Do you feel like you are thinking clearly today?" the judge asked.
"Yes," Kohberger replied.
Hippler then asked whether anyone had threatened him or anyone close to him to make him plead guilty.
"No," Kohberger said.
The judge also asked whether anyone had promised him anything beyond the confines of the formal plea agreement.
Again, Kohberger answered: "No."
Finally, Hippler asked the fundamental question of the hearing: "Are you pleading guilty because you are guilty?"
Kohberger answered: "Yes."
The judge ultimately found that Kohberger fully understood the charges and the possible consequences of his plea. Hippler ruled that the plea was given "freely, voluntarily, and was intelligently made."
Post-conviction relief
That courtroom exchange will now become a significant factor as Kohberger attempts to undo the conviction.
The initial guilty plea meant there would be no murder trial. On July 23, 2025, Judge Hippler sentenced him to the four consecutive life terms, plus an additional 10 years for the burglary charge.
At the time, the plea appeared to bring the long-running criminal case to an end. But more than a year later, Kohberger began a legal campaign to undo the conviction from behind bars. He is now known as inmate number 163214 and has already filed a string of complaints within the prison system.
On Monday, July 27, 2026, he filed a petition for post-conviction relief. This is a civil legal process that allows a convicted person to challenge their conviction or sentence based on constitutional violations. Through this petition, he is seeking to withdraw his guilty plea.
Kohberger has alleged that his former lawyers pressured him into accepting the plea. He has also claimed that he was "convinced to falsely confess." These are allegations made solely by Kohberger and have not been established by the court.
Judicial bias claims
Rauch filed the memorandum supporting this effort under seal on August 27, 2026. It remained shielded from public view until Tuesday.
The new filing does not establish that Kohberger was legally incompetent when he entered the courtroom to plead guilty. In fact, his original defense lawyers expressly denied that he was incompetent.
Instead, Rauch explained that the goal of the memorandum is not to show incompetence, but to bolster an argument that Judge Hippler may be biased against the defendant. Kohberger previously moved to have the judge disqualified from his case after Hippler termed him a "faceless coward."
The document reveals the defense's concerns about whether Kohberger could fully understand the rapidly changing circumstances of his case and make rational decisions about how to proceed.
Rauch wrote that the sequence of events does not itself establish that the pleas were constitutionally invalid. However, he stated that it raises a factual issue for the post-conviction court to consider: whether Kohberger's lawyers had enough time and assistance to ensure that he understood the circumstances confronting him and could meaningfully participate in the decision to resolve the case without a trial.
For now, Tuesday's disclosure of the sealed document does not change his convictions or sentences. He remains imprisoned under the four consecutive life sentences without the possibility of parole.
The attempt to remove Judge Hippler from the post-conviction proceedings is scheduled for a hearing on October 15, 2026. A potential evidentiary hearing on the broader effort to withdraw the plea has been set for June 2027, where the court will ultimately decide whether the concerns raised by his former lawyers are enough to affect his conviction.
