As the case is being built against the 28-year-old murder suspect Bryan Kohberger, search warrants for the suspect’s apartment and his office were unsealed in court on Wednesday, revealing items of interest that were recovered in the searches.

Although these warrants were initially sealed, a Washington judge ordered that the redacted versions be released, disclosing what the Washington State University Police found at these locations.

At the suspect’s office at Washington State University, where he was a Ph.D. criminal justice student, authorities found nothing relating to the case. However, at his apartment, they found multiple items of interest that may tie Kohberger directly to the murders.

According to the filings, police found two pieces from an uncased pillow with a “reddish/brown stain” on it, eight possible strands of hair, a potential animal hair strand, a disposable “nitrite type black glove,” and a mattress cover that is possibly stained with blood.

These items have since been sent to a lab for testing.

Kohberger is currently facing first-degree murder and burglary charges for the quadruple murders of four University of Idaho students.

Despite the evidence that has already been released to the public, there are five major factors that could keep Kohberger from being convicted for the murders.

First, one of the surviving roommates reported seeing a masked man in the hallway of her home around the time of the killings but did not call the police at the time. Her failure to act immediately allowed the murderer to flee the scene and dispose of any evidence. Additionally, the roommate’s testimony that the mystery man had “bushy eyebrows,” which have been compared to Kohberger’s, could be dismissed as circumstantial evidence.

Second, the police have not found the murder weapon. Although a knife sheath was found at the scene, the knife itself has not been recovered.

According to the knife manufacturer who made the sheath, the police contacted them but they don’t have anyone with Kohberger’s name in their system. Therefore there is no proof yet that Kohberger ever possessed such a knife.

Third, there has been no clear motive determined for the quadruple murders. An added element to the search for a clear-cut motive is why the murderer chose the four students, yet left the other two roommates alive.

Fourth, a DoorDash food delivery occurred at the home just minutes before the murders are suspected to have taken place. Based on when one of the surviving roommates reports seeing the masked figure leaving the home, the timeline issued by law enforcement suggests that Kohberger would have had only 15 minutes to break into the house and kill all four victims.

The fifth and final reason that Kohberger may not be easily convicted of the murders is that his attorney could claim that DNA evidence was ‘transferred’ to the knife sheath that was found at the murder scene.

Legal experts have weighed in on the DNA evidence, arguing that the evidence found on the sheath is not sufficient for an “open and shut conviction.”
