Netflix’s ‘The Idaho Murders: College Nightmare’ Asks Why Bryan Kohberger Spared Dylan Mortensen the Night Four University of Idaho Students Were Killed

Netflix’s true crime documentary has reignited one of the most haunting questions surrounding the 2022 University of Idaho murders. Viewers want to know why Bryan Kohberger left surviving roommate Dylan Mortensen alive that night, even after she reportedly came face to face with him in the King Road house.

The Idaho Murders College Nightmare was released on Netflix on July 29 and chronicles the crime and its aftermath, including the weeks long manhunt for the then suspected killer. The docuseries leans heavily on Dylan Mortensen’s own account of that night, and it is her survival that continues to fuel public fascination and speculation.

What Dylan Mortensen Witnessed Inside the King Road House

Around 4.17am, a security camera captured the sound of a barking dog, voices, and what sounded like a thud, and at some point around this time Dylan Mortensen was awoken and heard a male voice say it’s okay Kaylee, I’m here for you. She reportedly heard crying afterward and saw a masked man moving through the property.

While recounting the events of that night in the documentary, Dylan described hearing a man’s voice she did not recognize saying he was going to help her, and she noted the tone was not delivered in a nice way but in what she called a weird way with a weird tone. That detail, more than almost anything else in ‘The Idaho Murders College Nightmare’, has become central to why fans believe Kohberger chose not to harm her.

According to the documentary’s timeline, Mortensen attempted to call Kernodle, Goncalves, and Mogen multiple times, but the calls went unanswered, and she then began texting Bethany Funke saying she was freaking out after seeing a man in a ski mask. She and Funke then locked themselves inside Funke’s room rather than immediately calling for help.

Bryan Kohberger’s Guilty Plea and His Sudden Reversal

Bryan Kohberger pleaded guilty to the murders of four college students in their off campus home in the Idaho college murders case, and he is now attempting to withdraw that plea. The timing has stunned many, since his effort to reverse course surfaced just days before the Netflix documentary’s premiere.

Kohberger went up to the third floor and killed Mogen and Goncalves with a knife, leaving the knife sheath which would later connect him to the crime next to Mogen’s body, and after killing Mogen and Goncalves he encountered Kernodle, who had recently received a food delivery, and killed her, before killing Kernodle’s boyfriend Chapin, who had been sleeping in her room. Notably, Mortensen and Funke were the only two people in the house that night who were not physically harmed.

In an interview cited by the documentary’s reporting, Kohberger insisted on his innocence, and according to the New York Times, he stated that his actual innocence is his truth and that the plea, which he claims hinged on false promises and blatant disinformation, must be withdrawn. That statement has only added fuel to renewed public debate over what really happened inside the house.

Why the Documentary Still Cannot Answer the Motive Question

Despite extensive access to investigative documents, police bodycam footage, and people connected to the case, the documentary does not identify an alleged motive for Kohberger’s killings. That includes any definitive explanation for why he left Mortensen and Funke unharmed while killing the other four residents of the home.

Because Kohberger pleaded guilty weeks before his trial, a motive for the killings has never been publicly established. This legal reality means that even the filmmakers behind ‘The Idaho Murders College Nightmare’ were working without the benefit of trial testimony or cross examination that might have forced Kohberger to explain his choices that night.

Director Skye Borgman made a deliberate choice about how to frame Kohberger’s presence in the story. According to the Today show, Borgman said the series was built to be victim forward, holding off as long as possible before showing images of the perpetrator or even speaking his name aloud. That structural decision keeps the focus on the survivors rather than on speculation about Kohberger’s internal reasoning.

Dylan Mortensen’s Life Since Surviving the Attack

Mortensen has said she has suffered from debilitating panic attacks since the night of the murders, telling Kohberger during his sentencing that he has taken away her ability to trust the world. She attended Kohberger’s sentencing hearing and shared her own statement with the court.

Mortensen testified that she saw the figure while investigating noises outside her bedroom door, and though she discussed what she saw with Bethany Funke, nobody called 911 until roughly noon on November 13, per court documents. That delay has become a flashpoint in Kohberger’s defense.

Kohberger’s defense has challenged the accounts of Mortensen and Funke, arguing they waited about eight hours before calling 911 after realizing someone had entered the home. People previously reported that Funke expressed guilt over not contacting authorities sooner, a detail that adds another painful layer to an already devastating case.

With Kohberger now fighting to withdraw his guilty plea and no clear motive ever confirmed, the question of why he spared Dylan Mortensen that night in the King Road house may never get a definitive answer, so what do you think really happened in those final terrifying moments before Kohberger walked out of that house.
