• Bryan Kohberger is charged with four counts of first-degree murder.
• A knife sheath found at the crime site had a DNA match with Mr. Kohberger.
• Police have not yet identified a murder weapon.

The police took a reddish-brown stained pillowcase and hair strands from Idaho murder suspect Bryan Kohberger‘s apartment, according to an unsealed search warrant.

In connection with the deadly stabbings of four University of Idaho students, Mr. Kohberger was detained last month and is now charged with murder.

Police have not yet identified a murder weapon, a “fixed blade knife,” or a reason behind the deaths.

The defendant has not yet made a decision.

At Mr. Kohberger’s residence and office, police recovered “a collection of dark red,” cuttings from a pillow stained reddish-brown, part of a mattress cover with stains, a nitrate type black glove and a possible animal hair strand, according to the search warrant.

When neighborhood police first arrived at the crime site, they discovered a puppy that belonged to one of the deceased students, Kaylee Goncalves, and her ex-boyfriend.

Other items discovered were Walmart and Marshalls receipts, a Fire TV stick, and a vacuum cleaner dust container.

The rationale for Mr. Kohberger’s arrest, which was supported by a probable cause affidavit, included the fact that a knife sheath discovered at the crime site had a DNA match with Mr. Kohberger.

The white Hyundai Elantra that Mr. Kohberger was driving, which matched the description of a sedan seen close to the crime site, had already been found by authorities.

In connection with the deadly stabbings of Kaylee Goncalves, Madison Mogen, and Xana Kernodle, both 20 years old, as well as Ethan Chapin, 20, Mr. Kohberger is charged with four counts of first-degree murder.

On November 13, they were all murdered in a residence outside of campus.

According to Mr. Kohberger’s attorney, the defendant thought he would be cleared.

The 28-year-old was a graduate student at Pullman, Washington’s Washington State University’s Department of Criminal Justice and Criminology.

The date of the preliminary probable cause hearing is set on June 26.
