Dylan Mortensen is one of the two surviving roommates of the Idaho murders, the November 13, 2022, quadruple stabbing at an off-campus house on King Road in Moscow that killed four University of Idaho students. She was 19, asleep on the first floor, and came face to face with the masked intruder in the hallway without realizing anyone had been hurt. Her account of what she saw and heard, and the roughly eight hours that passed before 911 was called, became central to the case against Bryan Kohberger.
Who She Is and Where She Was That Night
Mortensen lived on the first floor of the three-story rental at 1122 King Road along with Bethany Funke, the other surviving roommate. Upstairs that night were Madison Mogen, 21, and Kaylee Goncalves, 21, on the third floor, and Xana Kernodle, 20, with her boyfriend Ethan Chapin, 20, on the second. All four were fatally stabbed in the early morning hours. Neither Mortensen nor Funke was physically harmed.
What She Saw and Heard
According to police interviews, grand jury testimony, and court filings, Mortensen was awakened around 4 a.m. by sounds she first thought were Goncalves playing with her dog, Murphy. She then heard Goncalves say something like “someone’s here” in a tone she described as frantic, “somewhere between talking and yelling.” Murphy, who Mortensen said did not usually bark, was barking.
Over the next several minutes she opened her bedroom door more than once. She reported hearing crying from the direction of a bathroom or Kernodle’s room, followed by an unfamiliar male voice saying, “It’s okay, I’m going to help you.” She told police the voice did not sound kind. In an initial interview she recalled the voice using Goncalves’ name; she later walked that detail back.
On the third time she opened the door, Mortensen saw a figure dressed entirely in black, wearing a mask that covered everything but his eyes and the bridge of his nose. She described him as male, roughly her height or a few inches taller, with a lean, athletic build she compared to a basketball player. She noticed one “bushy eyebrow” but could not identify a color. He was holding something near his stomach that she initially thought was a vacuum. He looked at her, said nothing, and walked toward a sliding glass door off the kitchen.
At the same time, she noticed Kernodle lying on her back near her bedroom doorway, but assumed Kernodle had passed out. Mortensen told investigators she did not perceive a threat, explaining that people often came in and out of the house. She acknowledged she had been drinking that evening, said her vision was blurry, and later told police she was “trying to determine what was real” and questioning whether her memories were actual events or her mind “playing with her.” After the figure left, she went downstairs to Funke’s bedroom. She told police she believed everyone in the house was asleep.
The Eight-Hour Gap Before 911
The 911 call was not placed until 11:58 a.m. that day. Text messages introduced in court filings show that around 4:20 a.m., Mortensen began texting and calling her roommates. She texted Funke that she was “freaking out” after seeing a “masked man” and described him as wearing “a ski mask almost.” Funke replied, “Come to my room,” and “Run.” The two locked themselves in Funke’s first-floor bedroom. Mortensen also texted Goncalves, “Pls answer,” and got no reply.
Neither roommate called police, friends, or family for hours after that. Defense filings introduced phone records showing both were active on their devices well before noon. Funke called her father around 7:30 a.m. about a toothache. Mortensen was active on Instagram for about two hours starting around 8 a.m. and also used Snapchat and Indeed. The two eventually asked a friend to come to the house because Mortensen was “too scared.” It was that friend’s boyfriend who told them to get out and call 911. When Funke placed the call, she told the dispatcher that a roommate was “passed out drunk and not waking up” and that they had seen a man in the house the night before.
The delay drew heavy public criticism. Elizabeth Cauffman, a professor of psychological science at UC Irvine, told reporters the brain’s amygdala can trigger a freeze response that overwhelms the prefrontal cortex, the region responsible for decision-making, and that the effect is especially pronounced in people between 18 and 25, whose prefrontal cortexes are still developing. She also cited cognitive dissonance, in which the brain rationalizes a frightening situation into the “least threatening explanation,” and suggested socialization may lead young women to downplay fear to avoid seeming “overly dramatic.” If the roommates talked it through together, Cauffman said, they may have “reinforced each other’s doubts instead of escalating to call 911.”
Her Role in the Criminal Case
Mortensen and Funke were both placed under a broad gag order that kept them from speaking publicly about the case for most of its duration. In court filings they were identified only by their initials, “D.M.” and “B.F.” Both were expected to be key prosecution witnesses, with prosecutors planning to use their testimony and texts to establish the timeline of the attack. Mortensen had already testified before a grand jury and had sat for multiple interviews with law enforcement.
Kohberger’s defense attorney, Anne Taylor, challenged Mortensen’s credibility aggressively. The defense pointed to her alcohol consumption, shifting descriptions across interviews, and the hours-long delay in reporting. Court filings flagged inconsistencies in her account, including evolving descriptions of the intruder’s height, the lighting, and whether she had heard specific names spoken. Mortensen herself acknowledged in interviews that she could not confirm the man she saw was Kohberger after viewing a photograph of him following his arrest, saying she only remembered the bushy eyebrow and the black clothing. The defense filed motions seeking to exclude or limit her testimony. Prosecutors argued her account was consistent enough on its core details to be reliable, and the judge sided with them.
The case never went to trial. Kohberger accepted a plea deal on June 30, 2025, and formally pleaded guilty on July 2 to four counts of first-degree murder and one count of burglary. The agreement eliminated the need for either surviving roommate to testify. On July 23, 2025, Judge Steven Hippler sentenced him to four consecutive life terms without the possibility of parole, plus a maximum ten-year sentence on the burglary count. The death penalty was taken off the table in exchange for Kohberger waiving his right to appeal.
What She Said at Sentencing
The July 23 sentencing hearing was the first time Mortensen spoke publicly about the killings. She addressed Kohberger directly, calling him “a hollow vessel, something less than human, a body without empathy, without remorse.” She told the court the murders had “shattered me in places I didn’t know could break” and described panic attacks that hit “like a tsunami out of nowhere.”
“My nervous system never got the message that it is over,” she said. She spoke about the friendships that were taken from her and said Kohberger would not define her future. “He tried to take everything from me: my friends, my safety, my identity, my future,” she said. “But he will never get to take my voice.” She closed by drawing a contrast between her life and his: “I get to live, and while I will still live with this pain, at least I get to live my life. He will stay here, empty, forgotten and powerless.”
Funke did not attend the hearing, citing ongoing trauma. Her statement, read by her friend Emily Alandt, described the guilt and regret she carries for not realizing what had happened sooner, and said she forces herself to go out in public despite still being afraid, because “I know that they would want me to keep living my life to the fullest.”
