Field of Science
Abstract
This article is based on the data obtained through the implementation of
the research task entitled “Selection of forensic methods for individual identification
of thermally degraded traces remaining in a minimal amount on a weapon
or a projectile” financed by the Ministry of Science and Higher Education
in Poland. The research conducted as part of the experiments was aimed at
proving what are the practical possibilities of genetic identification of a human
on the basis of biological traces secured from a shot projectile and from the
assignment of various examples of firearms from which the shot was fired.
These studies allowed for the selection of methods related to the acquisition
and analysis of DNA as a source for establishing the identity of unknown people,
whose material was thermally changed and was subject to other degradation factors.
They constitute a preliminary report, but allow us to assume that the further
continuation of the analyzes will significantly expand the knowledge in this
field. The assumption of the research task was to introduce a greater number of
weapons and many various obstacles on the flight path of the fired missile, but
due to some difficulties, the research experiments were not extended, which significantly limited the possibility of obtaining a greater amount of information
that could be used in practice during forensic examination. Nevertheless, the
findings made optimistic about the prospect of continuing the analyzes, and
with them, expanding knowledge in the area in question. After all, more and
more perfect methods of securing biological traces occurring in subanalytical
quantities (LCN), degraded in various ways, exposed to many unfavorable
environmental and weather factors, coming from hard-to-reach and polluted
surfaces, provide a great chance to learn and solve the hitherto unexplained
issues. This, the use of highly developed trace concentration techniques and the
introduction of more and more modern research genetically identifying material
of human origin and facilitating other, not less important, determinations.
