Kohberger’s cellphone “utilized cellular resources that would provide coverage to the King Road Residence between 9:12 a.m. and 9:21 a.m.,” the affidavit reads. The cellphone then traveled back to the Kohberger Residence, arriving at approximately 9:32 a.m., according to the affidavit.

Goncalves, Mogen and Kernodle were roommates and Chapin was sleeping over with his girlfriend Kernolde.

It was previously reported thattwo surviving roommates— who were unharmed — slept through it on the first floor of the house, but the affidavit states that one of the roommates was on the second floor andsaw the suspected killer.

According to the affidavit, the surviving roommate said she opened her door “after she heard the crying and saw a figure clad in black clothing and a mask that covered the person’s mouth and nose walking towards her.” The person walked past her and left the crime scene as “she stood in a ‘frozen shock phase,'” the affidavit reads. She then locked her bedroom door.

At the time of the slayings, Kohberger was a Ph.D student at Washington State University studyingcriminal justice and criminology. The university, which is in Pullman, Wash., is approximately eight miles away from the residence in Moscow, Idaho where the four students were killed.

Kohberger was in Pennsylvania visiting family for the holidays at the time of his arrest. Kohberger’s next pre-trial hearing is scheduled for Jan. 12. He has not yet entered a plea to the charges against him.
