Prosecutors and attorneys for a man charged in the killings of four University of Idaho students in 2022 began arguing some of the final ground rules they want for Bryan Kohberger’s trial.

The horrific murders shocked not only the small college town but also the entire country, and in December 2022 police arrested 28-year old Bryan Kohberger, a graduate student at the nearby Washington State University, after his DNA was reportedly found on a knife sheath left at the scene.
