A massive new evidentiary release in the Idaho student murders case has provided a chilling, granular look into the investigation, revealing nearly 2,800 crime scene photos from the King Road residence. The trove, released by Idaho State Police, represents the fourth and largest batch of visual evidence made public since the 2022 killings, offering unprecedented context into the forensic landscape of the home where four lives were brutally taken.
The photos document the harrowing scenes within the bedrooms where University of Idaho students Madison Mogen, Kaylee Goncalves, Xana Kernodle, and Ethan Chapin were stabbed to death in the early hours of November 13, 2022. While many images are too graphic to broadcast, they underscore the violent struggle that occurred, with one source describing Xana Kernodle’s bedroom as resembling “something out of a horror movie.” Kernodle suffered more than fifty stab and slash wounds.
Central to the state’s case is a critical piece of evidence now shown in stark context: the Ka-Bar knife sheath. Photographs depict the leather sheath, bearing the US Marine Corps insignia, lying face-down on Maddie Mogen’s bed, partially under the comforter and adjacent to her leg. Its placement, with the handle dangling off the mattress, raises persistent questions about whether it was dropped in a frenzied state and forgotten.
Forensic testing revealed a mixture of DNA from Goncalves and Mogen on the sheath’s snap, alongside an unknown male profile. A separate, single-source male DNA sample found on the leather strap was later matched through genetic genealogy to Bryan Kohberger, the Washington State University criminology PhD student who pleaded guilty to the murders last year and received four consecutive life sentences.
The extensive photo set also details the widespread use of Blue Star, a luminol-based chemical reagent, throughout the home. Investigators sprayed the πππ·πππΆππΈπ, which reacts with the iron in hemoglobin to reveal trace amounts of blood invisible to the naked eye, across vast areas including the kitchen counters, sink, and the sliding glass door.
This intensive application suggests investigators were exploring whether any attempt was made to clean the scene during the nearly eight-hour gap between the estimated time of the murders and the 911 call. The sliding door, which surviving roommate Dylan Mortenson told police the masked intruder used to exit, is shown heavily coated with the reagent.
Notably, the photos document areas linked to two unknown male DNA profiles, labeled “Unknown Male B” and “Unknown Male E,” which were collected from a handrail leading from the second floor to the ground floor. These degraded samples, never uploaded to the national CODIS database, were highlighted by Kohberger’s defense team as pointing to potential alternate suspects prior to his guilty plea.
Forensic expert Joseph Scott Morgan, reviewing the images, noted the “copious amount of Blue Star application” indicated investigators were “casting a wide net.” He contextualized the sheath’s presence, stating it appears “pristine” in its natural occurring state and was likely dropped in the initial, frenzied moment the knife was drawn, before the bloodshed began.
“The one thing that I can take away from this… the sheath bears evidence of the fact that this is something that happened prior to the unsheathing of the knife,” Morgan said. He theorized the perpetrator, potentially in a “ππππππ frenzy” and surprised to find two victims in one bed, simply forgot the critical item.
The release has sparked profound anguish for the victims’ families. The Goncalves family, who had previously sought to block the release of crime scene photos, expressed fury in a social media post, stating they received only minutes of warning before the images went public. They pleaded with the public to remember the human toll, writing, “Murder isn’t entertainment and crime scene photos aren’t content.”
The visual evidence solidifies the grim tableau investigators confronted: a home where signs of a college lifeβa beer pong table, an Idaho Vandals sweatshirt, a dog crateβcollided with a devastating forensic aftermath. The images show Kaylee Goncalves’s bedroom untouched, her bed covers pulled back, while her pink boots remained on the windowsill of Maddie Mogen’s room where she was killed.
As the legal proceedings concluded with Kohberger’s guilty plea, this unprecedented evidentiary drop provides a somber, detailed record of the crime that shocked the nation. It underscores both the brutality of the attacks and the immense, meticulous forensic effort undertaken to solve them, leaving an indelible and heartbreaking archive of a profound tragedy.
