Convicted murderer Bryan Kohberger spoke to his mother, Maryann Kohberger, for a total of more than three hours over several phone calls the same day he stabbed four University of Idaho students to death at an off-campus house. The first phone call came shortly after he arrived back at his residence in Pullman, Washington, that morning, about two hours after the murders. The second came on his way to revisiting the crime scene at 1122 King Road in Moscow, Idaho, hours later, digital forensics expert Heather Barnhart told People in a story published on Wednesday, August 13.
