As digital forensics experts analyzed the cellphone of Bryan Kohberger, the 30-year-old failed criticist turned convicted murderer, they drew similarities between him and the fictional main character of the book and movie, “American Psycho,” the narcissistic banker Patrick Bateman – and they discovered that he spent Christmas night a month after the slayings reading dozens of articles about serial killers.
“I looked at 'American Psychology' that day, how futile he was, he always bent like a naked photo, like him, like he was wearing pants, but nude at his waist, soft [in] The mirror moves forward and backward, making different expressions, but only for yourself.

“He took off his shirt, bent his muscles, took pictures of himself and went back to everything he had done before,” he said of Koberg. “Barring.”
Barnharts said they don't have the authority to share photos, but they describe them as narcissistic and weird. He even took pictures from weird angles, highlighting himself from the back and from his profile.
Experts revealed that Bryan Kohberger called his mom while returning to the Idaho murder the next day.

A selfie, previously announced after prosecutors included it in court documents, showed the bathroom smiling a few hours after killing, lifting his thumb up in his bathroom. Barnharts noted that there was a band aid on his knuckles and his hands were obviously scrubbed.

“He kept taking pictures and seemed to be helpless against them,” said Jared Barnhart. “They were just on his phone.”
He said it would make more sense if he shared it with others or posted them online, but Kohberger didn't do that. In fact, he had little conversation with anyone except his mom and dad, and he was called “mother” and “father”.
“He seems fascinated by himself, his parents and his body,” Heather Barnhart said.

According to Barnharts, Kohberger worked hard to minimize his digital footprint and successfully erased important information from his laptop. However, they found other abominable evidence – including his reading of serial killers online on Christmas night.
One of his key mistakes, the couple said, was that he downloaded some of these sites, not just read online, and analyzed a clear trace for them.

“All of these things are sitting there,” Jared Barnhart told Fox News Digital. “You know he's a criminology major. Can you forgive me? Maybe. But there isn't yet-not for this guy.”
But despite some incredible evidence, Koberg succeeds in hiding all traces of why he might have committed a crime.
“I think that's the most important thing for me, he cleaned up all the stories that victims' families need to hear, right? Why, how, why my kids? All of this went away,” Jared Barnhart said. “And, we wanted to find crazy things to tell these families, and that's not there.”

His search history includes searching for the term “mental ill,” his lawyers do not want to use it in trials, and the use of serial killers. Before his arrest, according to Barnharts, but after reading a news report on how police identified a suspicious vehicle in the murder of a white Hyundai Elantra for students, Kohberger seemed to panic and searched the car details and the replacement car. They said he also spent a lot of time streaming videos on YouTube and Tiktok.
“On his computer [personal computer]”mental ill” is a common word he enters the browser, but he could have said it was targeted at his profession or research.
However, from October 12 to November 16, 2022, he cleared his browsing history for about a month.

Kohberger pleaded guilty last month to one of four counts of first-degree murder and felony burglary. He did not have parole four times in a row, plus ten years. The plea agreement requires him to waive his right to appeal and seek a judgment.
When Kohberger was held in isolation at the Idaho largest security institute in the state prison near Boise, he was reportedly the target of harassment and ridicule by fellow prisoners.
