Police previously said in court documents that they found nothing of evidentiary value in Kohberger’s campus office, which he shared with two other Ph.D. students. Photos show a mostly empty desk, save for a couple of textbooks, and Kohberger’s name written on a dry-erase board alongside some notes and redacted materials. 

It’s not clear how useful the evidence they took from his apartment turned out to be – aside from possibly the hard drive in his PC. Experts from the digital forensics firm Cellebrite told Fox News Digital last month that they were given his phone and a single computer drive to examine.

From those devices, they saw he attempted to cover up his movements on the night of the murders and wiped a month’s worth of browser history – but he also spent that Christmas reading up on serial killers, took numerous “American Psycho” style selfies and had only 18 contacts in his phone while only keeping in touch with his immediate family. 

Kohberger pleaded guilty to four counts of first-degree murder and one of felony burglary in July, weeks before he would have gone to trial for the murders of Xana Kernodle, 20, Ethan Chapin, 20, Kaylee Goncalves, 21, and Madison Mogen, 21.

The plea deal spared him from the potential death penalty, which prosecutors said they would seek if he were convicted. He waived his rights to appeal and to seek a sentence reduction in exchange for four consecutive terms of life in prison with no parole, plus another 10 years.

He is being held at the Idaho Maximum Security Institution, where he is in protective custody in a wing known as J Block, which also houses death row inmates, including fellow murderer Chad Daybell.
