According to the probable cause affidavit, which has been reviewed by PEOPLE, a sheath of the knife that authorities believe was used in the stabbings was left at the scene in the bed where Mogen and Goncalves were found deceased. This is where detectives found DNA allegedly linking Kohberger to the crime, according to the affidavit. Agents took trash from Kohberger's parents' home in Pennsylvania to test for a DNA match, the documents state.

The roommate also said she heard crying on the night of the killings. At the time of the murders, Kohberger was a Ph.D student at Washington State University studying criminal justice and criminology. The university, which is in Pullman, Wash., is approximately eight miles away from the residence in Moscow where the four students were stabbed to death. Inside Idaho Murder Suspect's Alleged Chat Room Posts: I Can Do 'Whatever I Want with Little Remorse' Although a motive in the murders has not been revealed, the affidavit alleges Kohberger's cell phone pinged near the home on at least twelve occasions prior to the day of the killings. "All of these occasions, except for one, occurred in the late evening and early morning hours of their respective days," the affidavit states. University of Idaho officials recently announced that the house where the murders occurred will be demolished. "This is a healing step and removes the physical structure where the crime that shook our community was committed," University President Scott Green wrote. "Demolition also removes efforts to further sensationalize the crime scene." Scholarships are also being created in memory of Mogen, Goncalves, Kernodle and Chapin, Green said.
