A family member of murdered University of Idaho student Ethan Chapin has questioned why the roommate who survived the slayings didn't call the police.
An account believed to belong to Ethan's sister-in-law made several posts online before the arrest affidavit was unsealed for suspected quadruple killer Bryan Kohberger.
The court document detailed how surviving roommate Dylan Mortensen came face to face with a masked man on the night of the murders.
Ethan, 20, his girlfriend Xana Kernodle, 20, and Maddie Mogen, 21, and Kaylee Goncalves, 20, were all killed as they slept in the house on November 13.
His sister-in-law has since revealed that Dylan, who was in the property at the time of the killings along with Bethany Funke, called all of the roommates after she heard 'screaming and crying' coming from their rooms.
Posting in a thread on Reddit, she said: 'D supposedly called all the girls in the house after the crying and screaming stopped and no one answered – and she still didn't call the police.

His sister-in-law said that she needed to 'explain herself and her actions' on the night of the killings
'She needs to explain herself and her actions that night.'
When questioned about who did call the police, she added: '911 caller was the friend who went in because D called him to come over because she was scared from what she heard in the night.
'He went to Xana and Ethan's room first, then called 911. Why D or B didn't call the police once is the question.'
The affidavit revealed that Mortensen came face to face with a 'bushy eyebrowed' killer but was spared along with Funke.
Mortensen told police that she heard several scuffles throughout the night and opened her door where 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.
Police confirmed that a 911 call was made from the phone of 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 court documents show that she opened her bedroom door on several occasions throughout the night
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 '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 the 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.
The online discussion also dissected where the bodies were found, with the relative adding that both Xana and Ethan were found in her room.

Stacy Chapin said that 'nothing has changed’ since Kohberger’s arrest and that mourners should direct their anger elsewhere.
It comes after sources told NewsNation that Xana fought back against her attacked and repeatedly grabbed the knife used in the attacks.
Sources claim that her fingers were nearly severed from the student trying to fight back, with her father Jeffrey Kernodle giving the same information in November.
He told CBS 5 that autopsy reports showed that his daughter's skin showed 'bruises, torn by the knife.'
The FBI has also been forced to deny losing the suspected quadruple killer just moments after he left his apartment in Pullman, Washington, with his father, Michael, to return home to Pennsylvania.

Kaylee and Madison were found on the top floor of the Moscow, Idaho home. College lovers Chapin and Kernodle were found in a second-floor bedroom - while survivors Dylan Mortensen and Bethany Funke, both Kernodle's housemates, were sleeping on the first floor
Best friends Kaylee Goncalves and Madison Mogen, both 21, were murdered along with roommate Xana Kernodle and her boyfriend Ethan Chapin, both 20 in an off-campus home in Moscow
The pair had just pulled out of the parking lot of his graduate housing before he vanished from the sight of police – before being pulled over twice as he made his way back to the family home.
A Hanco*ck County Sheriff's Department confirmed Kohberger was pulled over by a deputy at around 10.41am on December 15.
Kohberger was pulled over twice within nine minutes while driving along I-70 in December, looking more concerned on the second occasion.
He remains in Latah County Jail awaiting a preliminary hearing in June, and he is expected to plead not guilty to the charges.
Court documents recently revealed that police discovered d a pillow covered in 'blood' in Kohberger’s Washington apartment.

A new search warrant, made public on January 17, shows that police found several hair strands, including one suspected animal hair, a black glove, a computer tower and one unnamed item with a collection of 'dark red spots'.
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'.
Investigators who raided the property back in December also picked up receipts from Walmart and two Marshall's receipts, as well as collecting the contents of his vacuum cleaner.
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 has since been unsealed with the approval of Whitman County Prosecutor Denis Tracy, who filed the motion on January 17.
Court documents 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. All the items are now being stored at the Washington State University Police department.
Kohberger was allegedly stalking the students in the weeks leading up to the murders. Pictured is the home where the murders took place, just over eight miles from where he worked as a PhD student and teaching assistant
Authorities reportedly said they wanted to see if any hair had been 'transferred' onto Kohberger and then back to his apartment – including that of Kaylee Goncalves' dog Murphy.
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 home where the students were murdered 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 their 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 the victims or Kaylee's dog.
His offices at Washington State University were also searched, but nothing was seized by officers.
