According to a body language expert, Bryan Kohberger seemed to show signs of satisfaction internally when he confessed to the brutal killings of four Idaho students.

Judi James told DailyMail.com the 28-year-old killer seemed to be ‘enjoying the attention’ during his plea deal hearing on Wednesday.

The expert observed that he remained calm but with a detached curiosity, and when his name was mentioned, he moved his chair away smoothly, almost like pulling out a drawer from a filing cabinet. Additionally, he stood up unnecessarily even after being advised by the judge that it was not required.

The expert, who is from the UK, mentioned that Kohberger seemed to relish the attention, notably by theatrically raising his right hand with fingertips above his head while taking the oath.

James added: ‘When sitting listening to his crimes, his demeanor looked passive and unemotional.

‘His one-word answers came quickly and in an assured, speedy, slightly sibilant voice that gave the impression of someone being politely helpful.’

She continued: ‘When he agreed to having committed those crimes, with each name and each cause of death being listed, his tone and his body language did not appear change. 

‘[There were] no apparent attempts to mask his eye expression or to dip his head in shame or guilt. Just an impassive-looking verbal agreement of guilt.’

Kohberger pleaded guilty to the brutal murders of four students at a rental home in November 2022 in a crime that shocked the nation.

The confession allows him to avoid a quadruple murder trial set for next month and a potential death penalty, although he is expected to spend the rest of his life in prison. 

His victims were Ethan Chapin, 20, Kaylee Goncalves, 21, Xana Kernodle, 20, and Madison Mogen, 21.

James added: ‘Kohberger sat in a confident symmetric pose in his seat listening impassively to the judge’s long introduction, his large, deep-set and cold bug-eyes watching with an expression of alien interest.

‘Suddenly, in standing mode, his pose and his demeanor suggested an air of menace. 

‘He towered above the court with his wide shoulders splayed and his back arched in an almost military-looking stance.

‘His arms hung at his sides, although not touching his torso and the too-short sleeves of his shirt that revealed long bare wrists and huge hands. 

‘The shirt looked tight at the neck, with stretch marks from neck to armpits as though the tie had been knotted too tight.’

His admission marked the first time the alleged killer has spoken in court. When asked whether he was pleading guilty because he is guilty, he coldly replied ‘yes’, as several of the victims’ heartbroken relatives broke down in tears.

It came moments after the prosecutor who handed him the plea deal broke down in court as he read out the victims names.

Prosecutor Bill Thompson choked up as he laid out the timeline of the shocking murders, growing emotional as he reached for a sip of water and a colleague patted him on the back. He then broke down again as he read out the names.

Kohberger stared coldly ahead as Thompson laid out the timeline, saying that he stalked the students’ home at 1122 King Road in Moscow, Idaho, before the slayings. 

Thompson said the state would have argued in court that Kohberger slipped in through a side door before killing Mogen and Goncalves on the third floor.

He said Kohberger then encountered Kernodle as she came down the stairs to pick up a Doordash order, and killed her with the same Ka-Bar knife he used on her roommates.

He then entered Kernodle’s bedroom and stabbed her sleeping boyfriend Chapin to death, Thompson said. 

Thompson said that after Kohberger murdered the four students, he then returned to the home at around 9am the next morning and lurked outside for around 10 minutes.

He then returned to his home, and took a selfie of himself in his bathroom, where he looked menacingly into the camera with his thumbs up.

Thompson admitted that he could not precisely place Kohberger in the murder house, but said phone data put him in the area.

His vehicle, a white Hyundai Elantra, was also seen circling the home on 1122 King Road, before surveillance cameras caught it fleeing the scene shortly after the murders at a high rate of speed.

As his victims’ loved ones sobbed in the courtroom, Kohberger showed no emotion and stared ahead.

Kohberger was arrested on December 30, 2022, and taken into custody in Pennsylvania over the murders.

Kohberger was eventually linked to the murders after a tan leather sheath found at the crime scene was shown to contain male DNA. This was eventually traced back to his family line, and matched to himself after a swab was taken.

His cellphone was also ‘pinged’ in the vicinity of the house around a dozen times in the month’s before the crime, including on November 13, 2022.
