A Washington State University Police officer pulled Bryan Kohberger over in his Hyundai Elantra roughly a month before the Idaho murders

Bryan Kohberger is seen pushing back at a Washington State University Police officer after an October traffic stop in newly released bodycam video made public Thursday evening, giving a new glimpse at the prior life of a suspected quadruple murderer.

"I think you know why I stopped you," the officer tells Kohberger. "You ran the red light."

"What actually happened is I was stuck in the middle of the intersection," Kohberger replies. "So, I was forced to go to the left."

"Yeah I was behind you the whole time," the officer says. "You're not supposed to enter the intersection at all for that reason because if the light turns red, then you're stuck in the intersection."

Kohberger claimed he was unfamiliar with how to drive through crosswalks because he was from a rural part of Pennsylvania.

"It never even occurred to me that was actually something wrong," Kohberger tells the officer.

The officer explains to Kohberger that, under Washington state law, drivers can't enter an intersection unless there's enough space for their vehicles on the opposite side.

However, he asks her to explain the rules for him, a request she accommodates.

"Can you explain that to me a little bit further?" Kohberger, a 28-year-old with a master's degree in criminal justice, asks the officer during the encounter. "So, in Pennsylvania, when you're stuck in an intersection, you have to make the left. What would the appropriate thing for me to have done been?"

"You're not supposed to block an intersection like that in Washington," she replies. 

He was eventually let off with a warning.

"I do apologize if I was asking you too many questions about the law," Kohberger says.

The release also includes officers banging on his apartment door Dec. 30, announcing their presence before serving a search warrant. He was already in Pennsylvania, where he was taken into custody by state police and the FBI at his parents' house that same day.

Documents describe Kohberger's sparsely furnished apartment

Previously unsealed court documents go into more detail about what police found in his apartment in Pullman, Washington. The new documents give a glimpse at what was missing.

"We also noticed, while clearing the apartment, it was sparsely furnished and fairly empty of belongings, including no shower curtain in the bathroom and the trash cans appeared empty," wrote WSU Assistant Chief of Police Dawn Daniels.

The search of his office in the school's department of criminal justice and criminology turned up nothing, Fox News Digital has previously reported. The new documents reveal his desk was completely empty.

In the apartment, police found hair samples, fabric with dark red stains and a single black glove and other evidence.

Police seized a single "nitrite-type black glove," a Walmart receipt and Dickies tag, two receipts from a Marshalls store, the dust container from a Bissell vacuum, eight "possible hair strands," a Fire TV stick, a single "possible animal hair strand," four other "possible" hairs and a computer tower. 

They also found a dark red spot, two "cuttings from uncased pillow of reddish/brown stain," and mattress covers with multiple stains.

Lastly, the school released an official letter from the school informing the suspected murderer and former Ph.D. criminology student he is no longer welcome on campus. It was signed by Kohberger from his Idaho jail cell.

Kohberger is accused of fatally stabbing four University of Idaho students Nov. 13. Their school is less than 10 miles from where Kohberger was studying.

Victims Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Ethan Chapin, 20, were found dead hours after a surviving housemate told police she heard strange noises and saw a masked man with "bushy eyebrows" leaving out the back door.

According to police in Moscow, Idaho, he allegedly entered their house at 4 a.m. and massacred them with a large knife. At least some of the students were believed to have been sleeping at the start of the attack, according to the Latah County coroner.

Police found a Ka-Bar knife sheath at the apartment, from which they recovered DNA, which allegedly helped link Kohberger to the killings.

Police also identified the white Hyundai Elantra in which he was pulled over in October as the suspect vehicle in the November attack.
