Hearing looks at rules for evidence and other details in Bryan Kohberger's trial for Idaho murders

BOISE, Idaho -- Prosecutors and attorneys for a man charged in the killings of four University of Idaho students in 2022 argued some of the final ground rules they want for Bryan Kohberger's trial in a Wednesday morning hearing.

Kohberger, 30, is charged with murder in the stabbing deaths of Ethan Chapin, Xana Kernodle, Madison Mogen and Kaylee Goncalves at a rental home near campus in Moscow, Idaho.

Kohberger, then a criminal justice graduate student at Washington State University, was arrested in Pennsylvania weeks after the November 2002 killings. Investigators said they matched his DNA to genetic material recovered from a knife sheath found at the crime scene.

When asked to enter a plea to the charges, Kohberger stood silent, prompting the judge to enter a not guilty plea on his behalf.

Jury selection in the case is expected to begin July 30, with the trial starting Aug. 11. The trial is expected to take nearly three months to complete.

Attorneys on both sides of the case have filed hundreds of pages of legal motions, including whether Kohberger should face the death penalty if he is convicted, whether witnesses should be allowed to testify about things like "touch DNA," and who should be allowed in the courtroom during the trial.

Can Kohberger's family members attend the trial?

The prosecution has listed Kohberger's family as potential witnesses. Typically, witnesses are excluded from trials until after they have testified so their testimony isn't influenced by other evidence they may see.

But the defense team says Kohberger's family should be able to attend because it is the humane thing to do and Kohberger relies on their support.

Prosecutor Ashley Jennings told 4th District Judge Steven Hippler that the defense shouldn't be able to dictate how the prosecution presents its case. She says putting the family members on the witness stand early in the trial would make the testimony out of context and out of order.

"This is like a gumbo," Hippler replied. "You all are going to put all the pieces you need into a pot, and at the end of the day, the jury is going to decide if it's a good soup or not."

He said he would take the matter under advisement and issue a ruling later.

"I can only imagine that the family of Mr. Kohberger is devastated by these things. It's nothing that they did, and their ability to be here to see the trial is important," Hippler said.

Will Kohberger's autism spectrum diagnosis be brought up if he is convicted?

If the jury finds Kohberger guilty, the defense team plans to submit evidence about his autism spectrum diagnosis as a "mitigating factor" that he should not be sentenced to death.

The purpose is to show jurors that some of his behaviors are a product of autism, defense attorney Anne Taylor said. For instance, Kohberger tends to be stoic and can sit very still for long periods of time, she said, and sometimes talks longer than other people might want him to talk.

Taylor asked the judge to issue an order that says Kohberger's autism-related characteristics can't be used by prosecutors as "aggravating factors," or reasons that he should get the death penalty.

The prosecution team countered that they have much better aggravating factors to present and don't plan to use Kohberger's autism spectrum condition if the case reaches the penalty phase. But they also don't want the defense to be able to chalk up anything as being related to autism.

The judge said he will issue a detailed ruling later, but for now is issuing a general ruling that the state can't use autism as an aggravating factor.

Is anyone else a possible suspect?

The defense team says they plan to present evidence of "alternate perpetrators," and their investigation into that is still underway.

But prosecutors want the judge to issue an order preventing defense attorneys from using a "shotgun approach" by throwing a bunch of names at the jury without offering substantiating evidence tying those people to the crime.

Defense attorney Elisa Massoth told the judge that there's a lot of evidence to support alternate perpetrators in the case.

"I would hope that the state, the court, can see that we are calculated and thoughtful in everything we're doing in this case and wouldn't treat alternative perpetrators any other way," Massoth said.

The judge says the defense team will have to make a "factual showing" that any suggested alternative perpetrators have a connection to the crime, and he doesn't want to do that during the trial.

Hippler said he would set a separate hearing before the trial so the defense can present the evidence they believe support the alternative perpetrator claims.

What about inflammatory evidence and terms?

Kohberger's defense team asked Hippler to prevent the state from relying on the excessive use of "emotional appeal" or gruesome photographs, and inflammatory words like "murderer," "psychopath" and "sociopath."

Hippler declined to issue a general order against inflammatory conduct but told both sides that he expected them to follow courtroom rules. He said he wouldn't allow the use of the terms "psychopath," "sociopath" or "murderer" during the evidentiary phase but left open the possibility that prosecutors could use "murderer" during closing arguments.

"Make no mistake, these murders, whoever did them, were ... horrific. And I expect that the evidence will reflect that," Hippler said. "When it comes to cumulative evidence or some that are unnecessarily graphic, I think we will address that on a case-by-case basis."
