Surviving Idaho roommate SAW killer moments after quadruple murder (2023)

A surviving roommate of the murdered Idaho students saw the suspected killer leave their house moments after the massacre took place, bombshell court filings reveal.

Dylan Mortensen saw the suspect - who was masked and dressed in all black - exit the house after one victim was heard crying and another said '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.

The newly-unsealed affidavit, which refers to Mortensen as DM, describes how she was confronted by the suspect after she investigated the disturbances - but apparently hadn't realized the murders had taken place.

Suspect Bryan Kohberger, 28, faces the death penalty if he is convicted over the murders of Idaho students Xana Kernodle and Ethan Chapin, both 20, and best friends Madison Mogen and Kaylee Goncalves, both 21, on November 13.

In her interview with police, Mortensen said she was awoken at around 4am by what sounded like Goncalves 'playing with her dog' in a third-floor bedroom.

A short time later Mortensen, who was in her second-floor bedroom, heard Goncalves say 'there's someone here', the haunting affidavit reveals. Mortensen looked out of her bedroom door but didn't see anything.

She looked out of her room a second time shortly after, 'when she heard what she thought was crying' coming from Kernodle's room, which is also on the second floor.

Mortensen then heard a male voice say something like, 'it's ok, I'm going to help you,' the affidavit states.

At 4.17am, a neighbor's security camera picked up audio of 'what sounded like voices or a whimper followed by a loud thud. A dog can also be heard barking numerous times.'

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'.

The affidavit adds: 'D.M. described the figure as 5' 10" or taller, male, not very muscular, but athletically built with bushy eyebrows. The male walked past D.M. as she stood in a "frozen shock phase".

'The male walked towards the back sliding glass door. D.M. locked herself in her room after seeing the male.

'D.M. did not state that she recognized the male. This leads investigators to believe that the murderer left the scene.'

Police said Mortensen's statements, combined with phone records, led them to believe the killings took place between 4am and 4.25am.

The 19-page probable cause affidavit released on Thursday lays out the early stages of the police case against Kohberger, including how his DNA was found on a knife sheath left at the scene, and how he stalked the victims' home in his white Hyundai Elantra before choosing to strike.

Kohberger was denied bail on Thursday during a brief court appearance in Moscow. He will return to court on January 12 for a status hearing.

At one point Kohberger grinned during the 10-minute hearing, which some of the victims' relatives attended.

He spent most of hearing looking directly at Judge Megan Marshall as she read him his rights and the five counts - four of murder and one of burglary - and answered ‘yes’ when asked if he understood each count.

Below, breaks down the key pieces of information from the new court documents, and some of the questions that remain unanswered.


The most damning piece of evidence is the fact that a DNA sample taken from Kohberger's family's home in Pennsylvania matched DNA found on the snap button enclosure of a knife sheath found at the murder scene.

The sheath is described as 'tan leather' with the USMC (United States Marines Corps) and 'KA-BAR' insignia stitched on its exterior.

A similar sheath can be purchased online for less than $20.

According to Moscow PD Officer Brett Payne - a rookie who joined the force in 2020 - the sheath was found on a single bed next to the stabbed corpses of Mogen and Goncalves.

'I noticed what appeared to be a tan leather knife sheath laying on the bed next to Mogen's right side (when viewed from the door).

'The sheath was later processed and had "Ka-Bar" 'USMC" and the United States Marine Corps eagle globe and anchor insignia stamped on the outside of it.

'The Idaho state lab later located a single source of male DNA (suspect Profile) left on the button snap of the knife sheath,' Payne wrote.

That DNA sample was sent for lab processing and then onto the FBI's genetic genealogy branch.

Through extensive research of public DNA databases, a match led to Kohberger's home.

On December 27, an undercover team of police seized trash from Kohberger's family home in Albrightsville, Pennsylvania

Police had already zeroed in on Kohberger by linking his white Hyundai Elantra to the scene.

On December 27, an undercover team of police seized trash from Kohberger's family home in Albrightsville, Pennsylvania.

A DNA sample from that trash returned a 99.98 percent match with the sample on the knife sheath.

Cops obtained a sample of his DNA on December 27, when they stole trash from his family's house in Albrightsville, Pennsylvania.

That sample returned a 99.98 percent match with the sample found at the scene to Kohberger's father.

A shoe print was found in the mud outside the murders house, just outside the sliding door that Mortensen said was used by the killer to escape.

Police studied that shoe print and found a 'diamond pattern' which is consistent with the sole of a Vans shoe

Police studied that shoe print and found a 'diamond pattern' which is consistent with the sole of a Vans shoe.

It's unclear if Kohberger owns Vans - the affidavit does not confirm the discovery of any shoe that has a sole print similar the one found at the scene.


A white Hyundai Elantra was observed on surveillance cameras in the vicinity of the crime, around the relevant time frame, but the absence of a front license plate made it harder for police to track down its owner.

On November 29, police obtained surveillance footage from the parking lot of Kohberger's apartment building, some 10 miles from the murder scene, in Pullman, Washington State.

Moscow Police officers visited the parking lot to obtain a license plate for the vehicle.

They ran a search, and found multiple incidents in which the car and its owner - Bryan Kohberger - had been pulled over multiple times in the past.

With Kohberger's name, police honed in on him and reviewed historic surveillance camera footage, along with phone records, going back several months.

A study of Kohberger's phone records and surveillance camera footage from Pullman, WA - where he lived - and Moscow, ID - the murder scene - revealed that he visited the area 12 times at least before November 13, the night of the killings.

Kohberger had to return to the state of Idaho to be formally charged and served with the search warrants that were used to secure his arrest.

Those documents are expected to be made public by the Idaho courts either during or after his appearance.

Kohberger is a PhD student studying criminology. He lived eight miles from the murder scene in student housing on the University of Washington's Pullman campus.

Through his public defenders, he has protested his innocence.His family, who hid their faces during a court appearance in Pennsylvania earlier this week, also believe he is innocent.

Kohberger's attorney in Idaho previously revealed his eagerness to return to Idaho to learn more about the authorities' case against him.

After the November 13 killings, Kohberger and his father, Michael, drove 2,500 miles in a white Hyundai Elantra from Idaho to Pennsylvania.


The two resounding questions that are not answered by the probably cause affidavit are did Kohberger know any of the victims, and what was his alleged motive?

It was previously revealed that there were 'connections' being found between the victims, namely Goncalves, and the suspect, but those connections have not yet been made public.

The probable cause affidavit lays out the evidence that led police to make an arrest but does not put forth the entire case against Kohberger.

That will emerge during trial - if the case gets to that stage.
