Bryan Kohberger caught on police bodycam before Idaho murders.

Newly released bodycam footage shows Bryan Kohberger arguing with a police officer during a traffic stop about a month before he allegedly murdered four University of Idaho students. Kohberger, who was a Ph.D. criminology student at Washington State University, was pulled over for running a red light and quibbled with the officer about the law. The officer eventually let him off with a warning. Kohberger is accused of brutally murdering the four students in their home and evidence found in his apartment includes hair samples, red-stained fabric, and a single "nitrite-type black glove." Kohberger's desk in the university's criminology department was found to be completely empty and he has been banned from the campus.
