Bryan Kohberger’s defense team faces mounting challenges in his upcoming murder trial as they attempt to ban certain phrases and argue his autism should exempt him from the death penalty, while the prosecution streamlines their strategy for the sentencing phase.
At a Glance
- Kohberger faces four counts of first-degree murder for the November 2022 killings of University of Idaho students
- Defense seeks to ban phrases like “bushy eyebrows” and “murderer” at trial, claiming they could bias the jury
- Judge ruled Kohberger’s family can attend the trial despite potentially being called as witnesses
- Defense argues Kohberger’s autism makes him “insufficiently culpable” for execution if convicted
- Prosecution will rely on guilt phase evidence and victim impact statements during sentencing if Kohberger is convicted
Defense Strategy: Block Key Terms and Highlight Autism
Bryan Kohberger’s legal team is pursuing multiple strategies to protect their client as his trial for the murders of four University of Idaho students approaches. Most recently, they filed motions to prevent a surviving roommate from using the phrase “bushy eyebrows” when describing the assailant. The defense argues this description could unfairly influence jurors since Kohberger himself has prominent eyebrows, essentially functioning as an identification in the courtroom despite the witness never formally identifying him as the perpetrator.
Additionally, the defense is seeking to prohibit the use of terms including “murder,” “psychopath,” and “sociopath” during the trial. In court documents, the defense contends: “To label Mr. Kohberger as a ‘murderer,’ the alleged weapon consistent with an empty sheath as a ‘murder weapon’ or to assert that any of the four decedents was ‘murdered’ by Mr. Kohberger denies his right to a fair trial and the right to be presumed innocent.”

Few corners of true crime have stirred as much fascination and debate as the murders of four University of Idaho students, Kaylee Gonsalves, Madison Mogen, Ethan Chapin, and Xana Kernodle, or the heartbreaking deaths…

Family Presence and Mental Health Examination
In a significant ruling, Judge Steven Hippler determined that Kohberger’s immediate family members will be permitted to attend his trial. This decision comes despite the possibility that family members might be called as witnesses. The judge emphasized that their presence “advances the values served by the right to a public trial” and noted there was minimal risk that family members would alter their testimony based on trial observations.
“Courts recognize that having defendant’s family members present at trial advances the values served by the right to public trial, i.e., ensuring fair proceedings; reminding the prosecutor and judge of their grave responsibilities; discouraging perjury; and encouraging witnesses to come forward.”, said Judge Steven Hippler.
The judge has also partly granted the prosecution’s request for a mental health examination of Kohberger. Defense experts have diagnosed him with autism spectrum disorder, obsessive-compulsive disorder, and attention deficit hyperactivity disorder. While prosecutors are allowed to conduct their own mental health examination, they are not permitted to conduct personality testing. These mental health diagnoses form a central part of the defense’s strategy against the death penalty.
Prosecution Strategy and Judicial Criticism
The prosecution has outlined a streamlined approach for the penalty phase should Kohberger be convicted. In a significant tactical decision, they announced they will not call any lay witnesses during sentencing. Instead, they plan to rely on testimony and evidence already presented during the guilt phase of the trial, supplemented by impact statements from the immediate family members of the victims.
“[Kohberger] has been receiving discovery in the same manner for over two years,” Hippler wrote. “[Kohberger] has not sought additional resources…to hire additional staff to review discovery or obtain litigation document control software to help organize and sort the evidence. His lead counsel insisted that she be allowed to take on a second high-profile capital case despite the voluminous discovery in this case.”
Judge Hippler has openly criticized defense attorney Anne Taylor for her handling of the case. The defense claimed the prosecution’s discovery process was inadequate, making it difficult for Kohberger to review evidence before trial. However, the judge pointedly noted that Kohberger has been receiving discovery materials in the same manner throughout the case and questioned the defense team’s approach to managing the extensive evidence.
Autism as a Mitigating Factor
Central to the defense’s strategy is Kohberger’s autism diagnosis, which they argue should make him ineligible for the death penalty. According to court filings, the defense describes Kohberger as having rigid thinking, obsessive-compulsiveness, and an eating disorder, with behaviors including compulsions around cleanliness and germ avoidance. They argue that these conditions affect his communication, social skills, and impulse control, making him “insufficiently culpable” for execution.
Despite these arguments, the judge has maintained that the death penalty remains a possible punishment if Kohberger is convicted. With the trial set to begin in August, both the prosecution and defense continue to fine-tune their strategies in what promises to be one of the most closely-watched murder trials in recent years.
