Washington State University Police seized a reddish-brown stained pillowcase from Bryan Kohberger's apartment, hair strands, and one nitrite-type black glove, according to a search warrant released on Wednesday.

Kohberger is accused of killing four college students in an off-campus home in Moscow, Idaho. According to the search warrant, animal hair was also discovered during the search of Kohberger's flat.

A dog belonging to one of the victims, 21-year-old Kaylee Goncalves, and her ex-boyfriend was discovered in the Moscow residence when local police officers first responded to the scene, according to the search warrant documents, and dog hair was one of the items police hoped to find during the search of Kohberger's apartment.

The murder weapon, which police have not yet recovered, was more elusive. The search warrant said, however, that on November 13, 2022, an empty knife sheath was found at the crime scene under or near the corpse of the 21-year-old victim Madison Mogen.

In their application for a search warrant, detectives noted that the home on King Road, where the killings took place, contained a significant amount of blood spatter, which happens when drops of blood are produced due to vigorous action.

The warrant said that police thought blood would be found on Kohberger's person, clothing, or shoes. The search warrant indicated that when investigating the murder scene, police discovered a latent shoe print with a diamond-shaped pattern identical to that of Vans sneakers. No blood test results were mentioned in the search warrant.

Investigators stated in the search warrant paperwork that they discovered a knife sheath made of tan leather lying on the bed adjacent to one of the victims. Afterward, the sheath was processed and stamped with the Ka-Bar, USMC, and United States Marine Corps eagle globe and anchor insignias.

The Idaho State Laboratory later identified a single source of male DNA on the knife sheath's button snap. Previously, law enforcement officials told CBS News that forensic evidence purportedly linked Kohberger to the crime scene in Idaho. An affidavit indicated that DNA was discovered on a knife sheath at the murder site.

According to the search request, police also seized a computer tower, Walmart and Marshall's receipts, the dust canister from a Bissell Power Force vacuum, and a Fire TV stick with a wire and socket. Police said on December 30 that Kohberger was captured in Pennsylvania on a fugitive from justice warrant and transported to Idaho, where he was formally charged with the murders.

Kohberger's office at Washington State University, which is a 15-minute drive from Moscow, Idaho, was also searched by the police. Kohberger was a Ph.D. in criminology and teaching assistant who had just completed his first semester at WSU, according to a statement from the university.

The 28-year-old is charged with four charges of first-degree murder and felony burglary for his alleged role in the deaths, according to Latah County, Idaho, prosecutor Bill Thompson, who announced during a news conference following the suspect's detention.

From Kohberger's apartment, police seized a single "nitrite-type black glove," a Walmart receipt and Dickies tag, two receipts from Marshalls, the dust container from a Bissell vacuum, eight "possible hair strands," a Fire TV stick, a single "possible animal hair strand," four other "possible" hairs, and a computer tower.

Once inside, investigators discovered many bedroom items, including a heavy crimson stain, two "pillow cuts with a reddish-brown stain," and mattress coverings with several stains. Documents indicate that he resided alone in the unit. He said that police had conducted an "outstanding" investigation and that, at this time, it may not be required to locate the murder weapon to get a conviction.

Kohberger reportedly attacked four victims around 4:00 a.m., when some of them were asleep, according to officials. When authorities arrived at a 911 call the following day, they discovered Xana Kernodle and Ethan Chapin, both 20 years old, died on the second floor.

According to the documents, officers discovered Kernodle and Chapin in the same second-floor room when they approached her bedroom. They discovered the dog of Goncalves, who had also survived the attack, in her bedroom. She and Mogen were found dead in the other bedroom on the third floor, in the same bed, with a Ka-Bar knife sheath that prosecutors believe had male DNA that was eventually traced to Kohberger.

Two more housemates also survived. One of them, described in court records only as DM, reportedly heard weeping coming from Kernodle's room and a male saying, "It's okay, I'll assist you." A short time later, police claim she witnessed a masked man with "bushy eyebrows" exit through a sliding door.

Authorities previously disclosed that Kohberger completed the semester following the crime. In newly announced documents, detectives stated that they suspected he intended to return to classes during the winter break.

Pennsylvania police and the FBI arrested Kohberger on December 30 at his parents' home in the Pocono Mountains. On the same day, their counterparts in Pullman, Washington, executed search warrants on his apartment and in his WSU office about the stabbings that occurred in Moscow, Idaho, approximately 10 miles away.

The court had previously ordered the warrants to remain sealed for two months, citing dangers to law enforcement, the investigation's integrity, and public safety. However, it left open the possibility that they may be made public sooner, Fox News reported.
