Forensic Doctrine of Staging: The Psychology of Distorting the Physical Environment of a Crime Scene

The key problem in investigating crimes involving staging is the complexity of identifying the
intentional distortion of the physical environment used to mask the true nature of the event. The
psychological mechanisms behind a perpetrator’s creation of a "false picture" lead to information
noise and the disorientation of the investigation. Existing methodologies do not always account for the
subtle connection between the subject's psychophysiological state and the nature of the traces they
leave, which complicates the recognition of "negative circumstances" and the identification of the
offender's personality through their behavioral signature in the physical environment.
The goal of the article is to study the psychological foundations of staging as a specific type of
forensic activity, identify patterns in the distortion of the physical environment, and develop criteria
for the psychological diagnosis of staging. Particular attention is paid to analyzing the internal
mechanism of forming a false alibi through material objects and identifying the typical "psychological
lapses" of a perpetrator when modeling a crime scene.
The study utilizes the systemic-structural method, the method of psychological modeling, the
comparative-analytical method, and an analysis of expert and investigative practice. The theoretical
framework is composed of works on forensic technology and judicial psychology, which allowed for
the synthesis of knowledge regarding material traces and the mental processes of the subject who left
them.
The analysis revealed patterns in the emergence of "informational contradictions" between the
ideal model of the crime in the mind of the perpetrator and its physical manifestation. It was
established that the redundancy or demonstrativeness of traces is often a consequence of psychological
tension and the subject's drive for hypercompensation. It is proven that identifying signs of staging
should be based on searching for inconsistencies between the objective logic of the event's progression
and the perpetrator's subjective perceptions of the scene's "plausibility."
Solving these problems will increase the efficiency of crime scene examinations, reduce the
time required to expose the guilty, and minimize the risk of investigative errors caused by artificially created versions. The findings contribute to the development of the forensic doctrine of staging and the
improvement of the tactics of investigative actions.
