Bryan Kohberger’s defense team on Thursday suggested there are “alternate perpetrators” and wants to include the theory during the trial.

During Thursday’s pre-trial hearing, Judge Steven Hippler revealed that Kohberger’s defense team made a filing which suggested an alternate suspect. Kohberger is charged with first-degree murder in the Nov. 13, 2022 deaths of University of Idaho students Xana Kernodle, 20, Kaylee Goncalves, 21, Madison Mogen, 21, and Ethan Chapin, 20.

Hippler did not rule on whether he is going to allow Kohberger’s defense team to present the “alternate perpetrators” theory during trial, but he asked for more evidence supporting their claim.

The former homicide detective said he thinks Kohberger’s defense team is presenting the possibility of another suspect in order to instill reasonable doubt in the eyes of jury members.

“When it gets before the jury, even if they can just get one juror and create reasonable doubt, that one juror could hang this trial and they’re doing all that they could to not have a guilty verdict against Bryan Kohberger,” he said.
