Police investigating the quadruple murder of four University of Idaho students discovered a pillow covered in ‘blood’ and gloves in suspected killer Bryan Kohberger‘s apartment.
Authorities searched the property on the Washington State University campus, in Pullman, just a few miles from the crime scene after his arrest.
A new search warrant reveals that police found several hair strands, including one animal hair, a black glove, a computer tower and an item that was a ‘collection of dark red’ spotting.
They also hauled away a pillow with a ‘reddish/brown stain’ on it and the top and bottom of a mattress cover with ‘multiple stains’.
Kohberger’s apartment was searched hours after she was arrested at his parents hom e in Pennsylvania on December 30
Forensic teams swooped on his property less than 15 minutes from the house where the gristly murders took place
Investigators also collected receipts from Walmart and two Marshall’s receipts, as well as collecting dust from his vacuum.
Authorities initially sealed the search warrant for the murder suspect’s Washington home – arguing that releasing the details could ‘prematurely’ end the investigation.
However, the document appears to have been unsealed, though it is yet to be uploaded to the Idaho court website.
Court documents seen by the New York Times show that eight strands of hair were recovered from the apartment, as well as a ‘possible’ animal hair.
They also recovered a Fire TV stick during their search, with all of the items being stored a the Washington State University Police department.
Authorities reportedly said they wanted to see if any hair had been ‘transferred’ onto Kohberger and then back to his apartment – including Kaylee Goncalves’ dog Murphy.

Kaylee’s dog Murphy was spared during the slayings, with officers finding him alone in her room
Murphy was found alive in Kaylee’s room by investigators who were called to the scene, and has now been returned to her ex-boyfriend.
The application also stated that the student’s home had a significant amount of blood from the victims – including ‘spatter and castoff blood’.
Investigators believe that it was likely that the killer would have had blood evidence on his body or clothing, and hoped to find trace evidence in Kohberger’s apartment.
However, they did not describe the results of any of the testing in the documents, and did not confirm if any hairs found matched to the victims of Kaylee’s dog.
His offices at Washington State University were also searched, but nothing was seized by officers.
Initially, the court ruled that the warrant should be sealed until March 1, claiming that if it were made public there would be a threat to ‘public safety’.

Court documents filed the same day as his arrest state ‘compelling circumstances warrant the temporary sealing ordered in this matter.’
Kohberger, 28, appeared in court last week but has yet to enter a plea for the murders of Maddie Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin.
Authorities released the probable cause affidavit against Kohberger just before his first hearing in Moscow, Idaho, on January 5.
It reveals how Kohberger turned his phone off on the night of the murders in an attempt to cover his tracks before the murders – turning it off before getting too close to the property.
Kohberger even returned to the scene of the crime at 9am on November 13 – just hours after he allegedly committed the quadruple murders.
The documents say that the criminal justice graduate stalked the property in the late evening and early morning on each occasion – bar one.

Officials have not revealed the exact dates that he canvassed the three-story property but confirmed that in August, he was pulled over just two minutes after leaving the area covered by the cell phone tower closest to the home.
A Latah County Sheriff’s deputy pulled him over on August 21 at 11.37pm as part of a traffic stop – in which he provided his number.
During the stop, which was recorded on the officer’s body cam, Kohberger was driving his white Hyundai Elantra.
The papers also included details on how Kohberger’s DNA was found on a knife sheath close to the bodies of Maddie Mogen and Kaylee Goncalves.
Authorities are still hunting for the murder weapon, with Moscow Chief of Police James Fry confirming they are yet to find it after Kohberger was arrested.
They confirmed they found DNA on a button of the sheath, which they then confirmed was Kohberger’s by digging through his trash.

It comes as law enforcement sources say the alleged killer was seen taking out garbage using surgical gloves several times at his parents home.
The officers were tasked with tracking Kohberger so they could arrest him as soon as a warrant was issued as well as trying to get hold of an object to compare DNA to a sample found at the scene.
He was also seen cleaning the inside and outside of his car, with the source adding that he didn’t ‘miss an inch’.
Kohberger was also reportedly seen taking out the trash to his neighbours bins at around 4am – with the contents being recovered by offices.
Unsealed court documents show the painstaking work done by officers, who matched the DNA found on the sheath to Kohberger’s by comparing it to his father’s DNA – which was a 99.9998 percent match.
The probable cause affidavit also revealed that Dylan Mortensen – who lived through the attack with Bethany Funke – heard several scuffles throughout the night and opened her door.
Mortensen told police that she saw a suspect dressed in all black with a mask covering his face and heard one of her housemates say, ‘there’s someone here’.
She also heard the suspect say, ‘it’s ok, I’m here to help you’ as he wandered the house committing the atrocity.

Kohberger even returned to the scene of the crime at 9am on November 13 – just hours after he allegedly committed the quadruple murders
Police confirmed that a 911 call was made by one of the surviving roommates at 11:58am who requested help for an unconscious person – though it has not been confirmed who spoke to police.
It has raised the question of why Mortensen didn’t contact authorities sooner, with some arguing that she may have been ‘frozen’ by fear.
The roommate did not contact authorities for six hours, despite hearing several of her roommates in distress as well as witnessing the killer.
Mortensen told cops she was awoken at around 4am by what sounded like victim Kaylee Goncalves, 21, ‘playing with her dog’ in a third floor bedroom.
She said she looked out of her room but didn’t see anything, looking again on second occasion when she thought Xana Kernodle was crying.
Mortensen ‘stated she opened her door for the third time after she heard the crying and saw a figure clad in black clothing and a mask that covered the person’s mouth and nose walking towards her.
After the man moved towards her she said that she remained in a ‘frozen shock phase’ as he continued past her – but let her survive.
Kohberger previously insisted that he would be ‘exonerated’ to his lawyer in Pennsylvania.
