The article deals with the formulation of the organizational and tactical foundations for the presentation of a person for identification by a 3D model of her appearance. The author notes that the named form of presentation for identification is a promising high-tech way of carrying out the mentioned investigative (detective) action, a logical development and a modern alternative to identification by photographs. To conduct the proposed study, a virtual (computer) scene was created, within which a demonstration of 3D models of a person’s appearance was worked out. It is advisable to involve at least two attesting witnesses in this procedural action and (or) to continuously film the identifying person at the same time as capturing the screen on which 3D models are shown. 3D models can be presented as recognizable faces on a monitor screen, in virtual reality (using VR glasses or a helmet) or in augmented reality (using AR glasses).
For identification, it is proposed to present 3D models of a recognizable face and at least three extras made using the forensic (signal) 3D scanning method. It is advisable to demonstrate the mentioned models to a recognizable person together and separately, as well as in a model of the environment in which the perception took place. In order to introduce into law enforcement, practice the procedure for presenting a person for identification using a 3D model, it is necessary to make appropriate changes to parts 6 and 7 of Article 228 Code of Criminal Procedure of Ukraine.
Key words: pre-trial investigation, investigative (search) action, presentation for identification, forensic (signal) 3D scanning, 3D appearance model.
