Trajectory of Blood Drops in an Experimental Model with the Use of a Firearm

Popis výsledku v původním jazyce

Background Blood marks analysis is a common technique used in forensics. However, current methods used have their limitations and deviations. The most commonly used trigonometric model is based on the linear movement of a blood drop, which disregards air resistance and gravitational force which affects all mass points in an area of space. Objective The aim of this paper is to map the flight trajectory of blood drops in an experimental environment with the use of a firearm and to evaluate the option of replacing the real world flight trajectory by a more accurately definable parabolic approximation. Method An experimental model was created which simulates the real world dispersion of blood in the case of firearm use. Blood samples with a volume of 100 ml were placed into a plastic bag and were shot at. For the purpose of the experiment was prepared wooden chamber (dimensions 2 x 2 x 2 m). Plastic bags containing blood samples were hanged in the chamber and positioned into the chambers center. Blood sa
