[The forensic medical characteristic of the gunshot exit wounds inflicted under the conditions of the bullet-resistant protection].

This article reports the results of a forensic medical expertise of the gunshot wound in a serviceman wearing a bulletproof vest with special reference to the behaviour of the bullet that underwent deformation upon hitting the jacket. The authors emphasize the difficulty of differential diagnostics between the entry and exit wounds in the cases like that described in the paper. A series of experiments provided the data suggesting the specific mechanism by which exit gunshot wounds are formed in those parts of the body that adjoin the material from which the bulletproof vest is made.

[The use of the three-dimensional modeling for the elucidation of the mechanism of injury formation and identification of the injurious agents].

The article reports a case of the application of the thee-dimensional models of an injury on a corpse and of a blunt trace-forming object with which it was presumably inflicted for the identification purposes. The models were constructed based on a series of the digital photographs processed with the use of the specialized software program. The work with the application of the three dimensional models made it possible to avoid disfiguring of the corpse, to determine the stages and conditions of infliction of the injury in the graphic editor software environment, and to arrive at the conclusion about the parts of the traumatic agent with which the injury was caused.

[Visualization of the reconstruction of a criminal event by means of 3D-modeling].

Forensic medical expertise carried out with a view to reconstruction of an event is a time-consuming procedure because it requires collection of a large amounts of various materials for the institution of a criminal investigation including physical evidence, photoboards of the site of an occurrence, etc. A forensic medical expert may encounter difficulties when reconstructing and scrutinizing the scene of action at a single computer monitor in order to analyze the behaviour of each participant of the event. Of great help in such situations are modern software programs allowing to visualize the site of an occurrence with a maximum approximation to reality, simulate the actions of the victim(s) and alleged offender(s), perform a large number of other forensic studies.

[The possibility of three-dimensional modeling of the mechanisms of damage formation in the framework of situational expertise].

This article was designed to share the experience gained with the three-dimensional modeling for the purpose of situational expertise intended to reconstruct the occurrence circumstances and check up the alternative investigative leads concerning formation of potential injuries to a concrete person. Simulation was performed with the use of the dimensionally scaled model of the place of occurrence as well as the models of the human head and body totally consistent with the anthropometric characteristics of the victim. The results of this work made it possible to reject several potential opportunities for the formation of injuries to the victim and identify the most probable version.
