Pullman, Washington - The search warrant that was granted for the apartment of Bryan Kohberger, the main suspect in the quadruple murder of four University of Idaho students, has been unsealed. Its contents reveal just what investigators obtained from his Washington State University apartment as evidence of a crime.

The day Kohberger was arrested in Pennsylvania to face four murder charges and a felony burglary charge in Idaho, law enforcement officers requested a search warrant for his apartment at Washington State where he was a PhD student.

Such documents had remained sealed to protect the integrity of the investigation. However, the docs were made public on Wednesday night, citing the unsealing of a revealing 19-page probable cause affidavit that inevitably led to Kohberger's arrest and return to Idaho.

Included in the 49-page search warrant were the pieces of evidence investigators collected from Kohberger's residence.

The evidence of a crime that was collected at the suspect's apartment included a nitrite black glove, a Walmart receipt with a Dickies brand tag, a dust collector from a Bissell Power Force vacuum, eight possible hair strands, one possible animal strand, one computer tower, one collection of a dark, red spot, two cuttings from an uncased pillow with a "reddish/brown stain" that was tested, and parts of a mattress cover with stains – one of which was tested.

Kohberger is currently being held at the Latah County jail on four murder charges as he awaits his preliminary hearing, which was set for June.

Investigators linked Kohberger to the scene with DNA from a leather knife sheath that was found next to one of the victims. The DNA was later matched to DNA found on a piece of trash taken from the suspect's family's home in Pennsylvania, which led to his arrest.
