A Washington State Court has unexpectedly unsealed the search warrants of murder suspect Bryan Kohberger’s office and home. Police recovered human hair strands, a black glove, a computer, and a mattress cover with dark red stains that could be blood. The search of his office at the Washington State University Department of Criminal Justice and Criminology turned up nothing, but his home unveiled significant evidence. 

The warrants were supposed to remain sealed for at least two months, with the court citing the risk to the investigation’s integrity, threats to police officers, and public safety. A judge decided to have them unsealed on Wednesday, January 18.

The search documents revealed previously undisclosed evidence that investigators found, including information gathered about the victims and their off-campus house, DNA, blood, and shoes with diamond patterned soles.

Kohberger is accused of four murders in the first degree and felony burglary count after police accused him of sneaking into a house outside the University of Idaho and stabbing four university students – three females and the boyfriend of one of the young women – at around 4 am on November 13, 2022.

With the new evidence, police allege that the suspect preplanned the murders and studied other murders and how to avoid arrest.

Police found a nitrite black glove, two Marshalls store receipts, possible human and animal hair, a Dickies tag, a receipt from Walmart, a Bissell vacuum dust collector, a computer and a fire stick.

In order to obtain the search warrant, police told the judge that they believed a search of Kohberger’s apartment and office would reveal evidence linked to the crime scene, because there was a lot of blood spatter in the victims’ apartment.

At the murder scene on November 13, two victims were found dead on the second floor, and two others on the third floor of the house.

On the third floor, where police believe the attacks started, they found a knife sheath next to two victims. The snap on the sheath later tested positive for Kohberger’s DNA.

After the brutal murders, Kohberger traveled to the victims’ house later in the day in the morning. He finished his semester and drove cross country with his father to Albrightsville, Pennsylvania, his parents’ home, and was arrested on December 30.

Investigators also said that the accused repeatedly messaged one of his victims on Instagram weeks before the slayings but did not get a response. He was following all his female victims on Instagram.
