Newly unsealed investigative records are offering a clearer view into how Idaho State Police reconstructed events inside a Moscow, Idaho, residence on the night four University of Idaho students were killed in November 2022. The documents focus less on sensational details and more on the investigative methods, evidentiary standards, and legal reasoning used to map a sequence of events later acknowledged by Bryan Kohberger in court.

The findings illustrate how modern homicide investigations rely on a combination of physical evidence, video surveillance, expert reconstruction, and procedural testing. For legal professionals, the case has become a detailed example of how timelines are evaluated, challenged, and ultimately presented within the criminal justice system.
According to Idaho State Police (ISP), investigators used evidence from inside and outside the residence at 1122 King Road to reconstruct Kohberger’s movements from the moment he parked his vehicle to the time he left the area. Surveillance footage from nearby cameras placed his car in the vicinity shortly after 4:00 a.m., a data point that became central to establishing the investigative timeline.
ISP determined that Kohberger entered the home through a second-floor sliding door and moved through common areas toward the upper level. Investigators concluded that he first went to the third floor, where one bedroom was unoccupied before he proceeded to another room. At that location, two of the victims, Kaylee Goncalves and Madison Mogen, were found later by authorities.

Court records indicate that after leaving the third floor, Kohberger encountered Xana Kernodle on the second floor. Prosecutors stated during the plea hearing that the evidence suggests the encounter may not have been planned, raising questions about how rapidly circumstances escalated once multiple individuals were present inside the home. Kernodle’s boyfriend, Ethan Chapin, was later found in the same bedroom.
Investigators noted that three of the victims were likely asleep when they were attacked, while one was awake and moving within the residence. Audio captured by a nearby security camera recorded sounds consistent with distress shortly before the suspect’s departure from the area, though officials emphasized that such recordings are interpreted cautiously and in conjunction with other evidence.
To better understand how much time the suspect could have spent inside the house, ISP conducted controlled test runs. Investigators retraced the suspected route through the residence, stopping at locations where victims were found and simulating actions based on forensic findings. These reconstructions were timed by supervising officers to establish minimum and maximum estimates.
The fastest test run measured approximately 90 seconds inside the home, while longer simulations lasted just over two minutes. Investigators then added estimated travel time from the parking location to the residence, testing both a direct route and a longer, less visible path through nearby wooded areas. When combined, the results suggested the entire sequence—from leaving the vehicle to returning to it—could have occurred in under four minutes.

However, investigators emphasized that these reconstructions represent theoretical minimums. Surveillance footage showed Kohberger’s vehicle in the area for a longer period, suggesting additional time inside the home. Authorities identified two key uncertainties: the interaction between floors after the initial encounter and the duration of resistance by one victim.
From a legal standpoint, such reconstructions are not designed to explain motive but to establish opportunity and feasibility. Prosecutors rely on them to demonstrate that a sequence of events is physically possible within the known timeframe, while defense teams often scrutinize assumptions embedded in these models.
Psychologists and criminal justice experts note that crimes involving rapid movement through confined spaces can defy simple explanations. Stress responses, perception distortions, and unplanned encounters can significantly affect behavior and timing. As a result, investigators typically present reconstructions as supportive evidence rather than definitive narratives.
The investigation also highlighted the role of forensic oversight. A knife sheath recovered from the scene provided DNA evidence that ultimately linked Kohberger to the residence through genetic genealogy. Prosecutors later described the item as a critical piece of physical evidence, particularly in the absence of additional eyewitness accounts.

Kohberger later pleaded guilty to four counts of murder as part of a plea agreement that removed the possibility of the death penalty. He is now serving four consecutive life sentences within the Idaho prison system, bringing the criminal proceedings to a close while leaving broader questions for legal scholars and investigators.
As cases increasingly rely on reconstructed timelines and probabilistic modeling, how should courts balance scientific estimation with legal certainty—and what standards should govern how such reconstructions are presented to ensure fairness, accuracy, and public trust in the justice system?
