(NewsNation) — Newly-released surveillance video shows Bryan Kohberger visiting multiple stores hours after he murdered four University of Idaho students.

In the video first obtained by Gray Hughes Investigates, Kohberger is seen walking into Costco in a button-up shirt, pants, and sneakers. He is drinking from a water bottle and is stopped by the greeter.

After a brief conversation, Kohberger exits the store, seemingly denied entry.

“It’s amazing to look at him, just walking around so casually knowing that he killed four different people earlier in the day,” Hughes said before a “Banfield” appearance Thursday.

“And interesting how he has his hand kind of in his left pocket. And that’s the hand that has the Band-Aid on it that was cut. So, trying to hide that as he’s walking around.”

Kohberger was seen with a wound on his hand in selfies he took after the murders.

Another piece of footage then shows Kohberger driving his Hyundai Elantra out of the parking lot, heading toward a coffee shop. He didn’t appear to order anything at the shop and paused briefly in the middle of the parking lot.

He headed to a different store and was seen in surveillance video grabbing a drink and paying for it at self-checkout.

Bryan Kohberger admits to murders

The surveillance video was released after Kohberger pleaded guilty and was sentenced to life in prison for killing Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin in November 2022.

He entered a guilty plea on July 2, sparing him from the death penalty, and was sent to the Idaho Maximum Security Institution.

Since being booked at the prison, he’s complained about the food and taunting by his fellow inmates.

He filed an initial complaint July 30, a week after his sentencing, saying other inmates were flooding their cells on purpose while subjecting him to “minute-by-minute verbal threats/harassment,” according to documents obtained by NewsNation. In a follow-up communication Aug. 4, Kohberger said he had faced threats of sexual assault.

Bryan Kohberger case file reveals new details

Court documents detailing the investigation into Kohberger have trickled out since his sentencing, and investigators shared new details about the probe in interviews with NewsNation.

Digital forensic experts Heather and Jared Barnhart told “Banfield” that Kohberger’s mom sent him a link to a news article about the murders before his arrest. Their investigation into his phone and devices also revealed that he had only 18 phone contacts saved, and exclusively referred to his mom as “mother.”

“Think about all the people you meet and the hundreds of random numbers,” Heather Barnhart said.

“And they were even identified as ‘girl I ran with,’ ‘second girl I ran with.’ A contact, then in parentheses ‘hair,’” she said. “Then there was ‘Mother’ and ‘Father,’ and his sister and just a few others.”

The release of some case files and crime scene photos has been blocked after families of Kohberger’s victims filed a lawsuit seeking to keep them sealed.

Kohberger’s motive for killing Mogen, Chapin, Kernodle and Goncalves is unknown.
