Idaho Killer’s Psych Report Reveals Four New Diagnoses

Bryan Kohberger’s closely guarded psychological evaluation has finally been unsealed, revealing a complicated history of developmental, psychiatric and eating disorders — along with new details about the convicted killer’s behavior behind closed doors.

The report, conducted months before Kohberger admitted murdering four University of Idaho students, says he was diagnosed in February 2025 with Autism Spectrum Disorder Level 1, obsessive-compulsive disorder, ADHD and Avoidant/Restrictive Food Intake Disorder, commonly known as ARFID.

But those were not the only conditions detailed in the newly public documents.

The evaluation also says Kohberger previously met criteria for Developmental Coordination Disorder, an unspecified depressive disorder, anorexia nervosa and opioid use disorder. His opioid disorder, linked to a heroin addiction during his teenage years, was described as being in sustained remission.

The revelations come more than a year after Kohberger stunned the country by pleading guilty to the November 2022 murders of Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20.

And with Kohberger now trying to undo that guilty plea, the newly released psychological records are putting his mental state back under an intense spotlight.

Defense expert Dr. Rachel Lawson Orr conducted the neuropsychological evaluation after being brought in by Kohberger’s lead attorney, Anne Taylor.

According to the report, Kohberger met with Orr six times over approximately three months for interviews, psychological testing and evaluation. His parents and two sisters were also interviewed about his behavior.

Orr described Kohberger as displaying a “restricted range of facial expression,” with a generally stoic demeanor. His smiles were reportedly slight, while social smiling could be inconsistent or absent.

She also documented what she viewed as unusual social behavior, including limited gestures, an atypical speaking cadence, awkward interactions, difficulties recognizing humor and a tendency to redirect conversations toward his own experiences.

At times, Kohberger allegedly maintained an intense gaze or made abrupt, matter-of-fact comments without appearing to recognize how they might come across.

During testing, Orr said she also observed impulsive tendencies.

According to the report, Kohberger sometimes rushed through tasks, violated testing rules and demonstrated what Orr characterized as generally poor insight into his own behavior.

His relatives reportedly described similar patterns stretching back years.

Family members told the psychologist that Kohberger struggled with nonverbal communication, displayed a limited range of facial expressions, engaged in rigid thinking and had difficulty adapting when his routine changed.

They also described repeatedly attempting to coach him through social situations, reportedly with little success.

Those observations helped Orr conclude that Kohberger met the criteria for Autism Spectrum Disorder Level 1 without accompanying intellectual or language impairment.

Crucially, however, nothing in the evaluation establishes that autism, OCD, ADHD or an eating disorder caused Kohberger to commit murder. Millions of Americans live with developmental or psychiatric conditions without committing violent crimes.

That distinction became part of a heated legal fight before Kohberger’s guilty plea.

Taylor argued that her client’s mental health and developmental disabilities should potentially be considered mitigating evidence. She objected to efforts by prosecutors that the defense characterized as treating those conditions as aggravating factors.

Taylor argued in court filings that doing so risked effectively “criminalizing his status as a disabled person.”

The defense also made clear that the evaluation was not commissioned to claim Kohberger lacked the mental capacity to stand trial or understand what he was doing.

Instead, Orr could have been called to testify if prosecutors challenged the defense’s characterization of Kohberger’s psychological condition.

That showdown never happened before a jury.

On July 2, 2025, Kohberger stood before Judge Steven Hippler and pleaded guilty to four counts of first-degree murder and one burglary charge.

When Hippler asked whether he was pleading guilty because he was actually guilty, Kohberger answered, “Yes.” He separately admitted deliberately killing each of the four students.

The plea deal spared Kohberger from a potential death sentence.

On July 23, 2025, Hippler sentenced him to four consecutive life sentences without the possibility of parole, plus another 10 years for burglary.

For months, that appeared to be the final chapter in one of America’s most infamous murder cases.

Then Kohberger made another stunning legal move.

In July 2026, he filed a post-conviction challenge seeking to withdraw his guilty plea, alleging ineffective assistance from his former attorneys. Legal experts have noted that overturning the deal could be difficult because Kohberger waived substantial appeal rights when he pleaded guilty, though claims involving ineffective counsel can potentially provide a separate avenue for challenging a conviction.

The newly released evaluation therefore arrives at an extraordinary moment.

It offers the public its most detailed glimpse yet into Kohberger’s psychological history while his lawyers attempt to reopen a case many believed had been permanently settled.

Still unanswered is the question that has haunted the victims’ families and the public since the killings: why?

Kohberger admitted that he deliberately murdered Goncalves, Mogen, Kernodle and Chapin, but he has never publicly explained his motive.

Even when given an opportunity to speak at his sentencing, Kohberger declined.

Now, despite four murder confessions, four life sentences and hundreds of pages of court records, the darkest mystery surrounding the Idaho killings remains intact.
