He has exercised his right to remain silent during the court case, so a not-guilty plea was entered on his behalf earlier this year.
The court document filed Wednesday is the first time Kohberger has said anything about his whereabouts on the night of the stabbings.
His defence team submitted it after prosecutors asked the court to force Kohberger to reveal if he intends to offer an alibi.
“Kohberger has long had a habit of going for drives alone. Often he would go for drives at night,” his defence attorney, Anne Taylor, wrote in the document.
“He did so late on November 12 and into November 13, 2022.”
Kohberger isn’t claiming to be in any specific location at any specific time, according to the document, and may have witnesses who can corroborate that he wasn’t at the home where the students were killed.
His defence team is still going over transcripts of grand jury testimony and other evidence from the investigation, his attorneys wrote, so it is too soon to detail exactly who those witnesses might be and what they might be able to testify about.
“The defence has stated all that can be firmly stated at this time,” Kohberger’s attorneys wrote.
Idaho law requires that defendants notify the prosecution if they intend to present an alibi defence, which is generally a claim that they were somewhere other than at the crime scene and have witnesses who will verify that.
The slayings shocked the rural Idaho community and neighbouring Pullman, Washington, where Kohberger was a graduate student studying criminology at Washington State University.
