Bryan Kohberger was captured on police body cam footage during a routine traffic stop in 2022, just a couple months before he murdered four University of Idaho students … and he’s recorded insisting he’s a super honest guy.

New video — which prosecutors planned to present at trial — has now been released after Kohberger has already pled guilty to his brutal killings … and, it starts when a cop stops him for allegedly going 43 mph in an area with a 35 mph speed limit.

The Latah County sheriff’s deputy pulls up to the window in the August 2022 stop … and notices Kohberger isn’t wearing his seat belt. He asks if Kohberger was wearing his seat belt while he was driving, and BK admits he wasn’t.

That’s unfortunate for Kohberger … ’cause this cop says he’s got a mandate from his superiors to catch people without their seat belts.

The cop writes Kohberger a $10 citation … who then tells the cop he’s “obviously an honest person” — and questioning how the cop would’ve figured out if Bryan was wearing a seat belt if he hadn’t told him.

BTW … according to documents released by the prosecutor, this traffic stop was made on a night when his cell phone pinged off a tower which covers the house where he killed four people — an area he allegedly visited multiple times in the lead-up to the slayings.

However, prosecutors insist they only planned to introduce this video to identify Kohberger and establish he drove a white Hyundai Elantra … the vehicle spotted near the murder scene in November 2022, not necessarily to prove he was near the house in August.

This wasn’t the only time Kohberger was pulled over … remember, he schmoozed his way out of a ticket just a month before killing Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin.
