THIS IS HORRIFYING! What really drove Bryan Kohberger? Top legal experts and criminal profilers expose THE DARK TRUTH behind the Idaho student murders that shocked the nation

Because Bryan Kohberger accepted a plea deal in the killing of four University of Idaho students, he avoided the death penalty, a trial and never had to state a motive.

On Nov. 13, 2022, Kohberger — who was a Ph.D. student at the nearby Washington State University — drove to an off-campus home in Moscow, Idaho, where five female students lived. He proceeded to fatally stab three of the roommates Kaylee Goncalves, Madison Mogen and Xana Kernodle, as well as Kernodle’s boyfriend, Ethan Chapin.

It took authorities over a month to arrest Kohberger via DNA evidence in Pennsylvania. He was charged with four counts of first-degree murder but maintained his innocence.

Ahead of his scheduled August 2025 trial, Kohberger changed his plea and agreed to a deal in which he pleaded guilty to the murders to avoid the death penalty. The deal also meant Kohberger never went to trial where a possible motive could’ve been 𝓮𝔁𝓹𝓸𝓼𝓮𝓭.

One year after he received four consecutive life sentences, Kohberger filed a petition to reverse his plea deal and obtain a trial by alleging his attorneys withheld “exculpatory discovery.” Kohberger is fighting his guilty plea from behind bars at the Idaho Maximum Security Institution.

In the near four years since Kohberger killed the four students, he has not spoken about a possible motive but experts and lawyers have shared their theories. The Netflix three-part docuseries The Idaho Murders: College Nightmare, which premiered on July 29, revisits the tragedy.

So, what have experts and lawyers said about Bryan Kohberger’s motive? Here’s what we know.

During Kohberger’s plea hearing in early July 2025, Latah County Prosecutor Bill Thompson detailed the night of the murders and said there was “no evidence there was any sexual component or sexual assault on any of the victims. I want to make that clear so there’s no speculation.”

However, days later, Steve Goncalves, whose daughter Kaylee was one of the four victims, shared during an appearance on NewsNation’s Banfield that he strongly disagrees with Thompson’s remarks, based on information he allegedly got from individuals involved in the investigation.

“People got so angry at what was happening in that courtroom that they would literally pick up their phone and call us and say, ‘This is what’s on Bryan’s phone. This is what he was searching. This was sexually motivated,’ ” Steve claimed. “I don’t care what Thompson said.”

Since the gag order in the case had just been removed, Steve was able to share more about why he disagreed, alleging that somebody involved in the investigation informed him of Kohberger’s “weird, weird 𝒑𝒐𝒓𝒏 fetishes,” which allegedly included “drunk passed out girls and gagging girls.”

“[T]hose are two things that were part of that crime scene, so for Thompson to say that there was no sexual assault…” Steve claimed, adding, “Of course, there wasn’t [evidence of sexual assault]. He didn’t have enough time. Somebody came up there.”

Days later, Kohberger was given a final opportunity to speak before his sentencing by an Idaho judge. Instead of defending himself, he uttered just three words — “I respectfully decline.” Then, he left the courtroom, without acknowledging his mother and sister.

Members of the technology forensic evidence team that investigated Kohberger’s cell phone and computer explained in The Idaho Murders: College Nightmare that his lack of contacts, internet searches and apps led them to believe he was cautious and taking extra steps to not get caught.

In addition, forensic pathologist and former Chief Medical Examiner of Onondaga County Mary Jumbelic, M.D., told PEOPLE that she believes his motive related to killing the three women differently than the one male victim.

“The three young women show a pattern of overkill by the perpetrator,” Jumbelic told PEOPLE in February 2026, while explaining that overkill “is when the infliction of injuries exceeds the force necessary to cause death,” and can indicate an “intense emotional rage.”

“Behavioral profilers say that this type of injury indicates a strong motive and a need to dominate,” she said.

In addition to Kohberger not disclosing his motive for the murders, prosecutors have also been unable to find evidence to suggest a particular reason for the killings. After Kohberger took the plea deal in early July 2025, Thompson presented some of the evidence gathered throughout the case and shared that they had failed to locate the murder weapon.

When it came time to discuss motive, Thompson shared that investigators found evidence of Kohberger’s phone pinging the cellular tower in the area of the victims’ off-campus home multiple times in the months leading up to the murders. However, Thompson said prosecutors still could not connect the killer to his victims.

“We do not have evidence that he had direct contact with [the home], but we can put his phone in that area at those times,” Thompson said.

In exchange for Kohberger’s plea, prosecutors agreed that they would not seek the death penalty. Instead, on July 23, 2025, Kohberger received four life sentences, plus 10 years for a burglary charge and $270,000 in fines and civil penalties.

“He’s the only one that has the ‘why,’ “ Idaho State Police Lt. Darren Gilbertson told ABC News in July 2025. “And oftentimes that ‘why,’ it may only make sense to him.”

However, Kohberger’s petition to reverse his plea and request a trial could potentially drum up further information on a motive. Kohberger alleged that he was “convinced to falsely confess” through “coercion, disinformation, false promises and withholding of exculpatory discovery.”

Although Kohberger claimed his attorneys failed to tell him about “unknown hair in Ethan Chapin’s hands,” he isn’t guaranteed a trial. Former federal prosecutor Neama Rahmani told PEOPLE that he believes “this petition is going to be denied.”

“If the defense knew that the prosecution failed to disclose the existence of this hair or any other exculpatory material, they would have filed their own motion, because that was a way they could’ve gotten the death penalty struck from the case,” Rahmani said. “Bryan Kohberger would be freerolling. He would roll the dice and go to trial.”
