Court documents released by the Moscow Police Department and Latah County courts shattered months of public speculation regarding the tragic homicides at the University of Idaho. The central piece of evidence, the probable cause affidavit compiled by Officer Brett Payne, details how investigators zeroed in on Bryan Kohberger through a combination of cellular tower records, surveillance footage, and touch DNA left at the crime scene. Understanding these specific documents clarifies how law enforcement built the case before making an arrest.
The primary search intent behind looking up these records is to find exact details on how police identified and tracked the suspect. Rather than relying on rumors, the court filings provide a verified timeline of the events on November 13, 2022, when four students—Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin—were killed. The documentation outlines the digital footprint and physical clues that bridged an anonymous vehicle sighting to a specific individual.
The Crucial DNA Evidence on the Knife Sheath
Physical evidence formed a cornerstone of the initial arrest warrant. Inside the room where two of the victims were found, investigators recovered a leather knife sheath laying on a bed.
The Idaho State Laboratory processed the metal snap of this sheath and isolated a single source of male DNA. When law enforcement later obtained trash pulls from the suspect's family home in Pennsylvania and compared the profile, laboratory analysis indicated that the DNA matched the profile of the suspect's biological father, with statistical probability showing that over 99.9998% of the male population would be excluded. This biological link gave detectives a concrete physical anchor for their theory.
Vehicle Tracking and Video Surveillance
Cell phone towers and traffic cameras played a massive role in tracing the movements of a white Hyundai Elantra. Police pulled footage from local businesses, residential security systems, and Washington State University campus cameras.
- The Arrival: Cameras captured a white Hyundai Elantra driving past the victims' King Road residence multiple times beginning around 3:29 a.m. on the night of the incident.
- The Departure: The vehicle was recorded leaving the area at a high rate of speed around 4:20 a.m.
- The Cross-State Check: University police officers at Washington State University identified a white Elantra registered to Kohberger, prompting local authorities to flag the license plate.
Digital Footprints and Cellular Data
Cell phone records subpoenaed by investigators showed that the device associated with Kohberger pinged towers near the victims' home on a dozen occasions prior to November 13, 2022. Most of these late-night or early-morning visits occurred outside normal social hours.
On the night of the murders, data indicated that the phone disconnected from cellular service around 2:47 a.m. and reconnected near Palouse, Idaho, at approximately 4:48 a.m. Investigators noted this blackout period aligned with the estimated window of the crimes, suggesting the device was either powered off or placed in airplane mode to avoid active tower tracking.
Timeline of the Surviving Roommates
The documents also clarify the timeline observed inside the residence by the two surviving roommates, identified in records as D.M. and B.F.
Roommate D.M. stated she was woken up around 4:00 a.m. by sounds resembling a dog playing upstairs, followed shortly by a voice she thought came from victim Xana Kernodle's room. D.M. opened her door three times. During one of these instances, she reported hearing crying and a male voice stating something to the effect of, "it's okay, I'm going to help you". She subsequently opened her door and saw a masked figure dressed in black walk past her toward the sliding glass door.
Frequently Asked Questions
When was the probable cause affidavit made public?
The document was unsealed and released to the public on January 5, 2023, coinciding with the suspect's first court appearance in Idaho after extradition from Pennsylvania.
Did the affidavit mention a specific motive?
No. The probable cause document focuses strictly on establishing the timeline, physical evidence, and digital tracks required for an arrest warrant rather than exploring a concrete motive.
How many people lived in the King Road house?
Six students rented the home, though two room occupants were asleep on the ground floor and survived the attack unharmed.
Are all case files completely public now?
While the initial affidavit and search warrants are accessible through court archives, various gag orders and protective motions have restricted the release of certain supplemental discovery materials to protect the integrity of ongoing legal proceedings.
