The main signs of inlet gunshot wound inflicted from non-close shot distance are the following: central defect of the tissue, presence of abrasion and rub zones along the margins. During experimental study high variability of these signs was stated and new morphologic characteristics of inlet gunshot wound were detected.

Possibility of using principles of criminalistic identification theory in investigation of objects of medicolegal expert evaluation is discussed. These principles were analyzed and shown to extend the objects of medicolegal identification, which however possess certain features influencing the specific character of their investigation.

On the basis of equations of external ballistics and probability theory the largest possible distances of free (independent) flight of gunshot powder and metal particles having different forms and sizes were calculated. Experimental control of the calculated data for different types of battle and sports hand fire-arms was carried out. ⋯ In experiments with cartridges equipped with bullets the distances of free particle flight were significantly lesser (by 53-65%) which may be connected with effect of gunshot projectile on the process of particle distribution. Reversed adapted formulas and calculation variants are presented.

In this article a practical case is described when gunshot directions and position of a victim's body at the moment of each shot were determined by natural simulation using an LG-78 laser (made in the form of a gun).
