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.

Prosecutors say Bryan Kohberger’s defense team will argue at his murder trial that someone else could have planted a knife sheath with Kohberger’s DNA at the home where four University of Idaho students were killed in 2022.

Idaho prosecutors say a man charged in the stabbing deaths of four University of Idaho students shouldn’t be allowed to offer an alibi defense unless he takes the stand himself during the murder trial later this year.

Attorneys for a man charged with murder in connection with the killings of four University of Idaho students are asking a judge to throw out most of the evidence in the case.
