The article deals with criminological experiment and the possibility of using computer modeling. The paper describes the current possibilities of using computer simulation and the possibility to use it for clarifying the versions in the case of a specific crime. The Perspective Method is Virtual Crash 3. This is a certified software that has been developed for forensic engineering and biomechanical applications. With this method, it is possible to simulate situations that can not be practiced by a real experiment with a mannequin or a living person. A computer simulation of human movement can very accurately illustrate the likelihood of individual versions when assessing a person's fall from a height.
