Techniques of chemical analysis in forensics

Abstract

The main purpose of the article is the development of knowledge related to finding out and establishing the truth through the technical-scientific interpretation of the traces left on the spot by criminals, aiming at the perfection of the applicable legislation in the field and the nuance of alternative-traceological solutions regarding the ways of establishing the truth through the interpretation of biological traces, respectively: traces of a hairy, odontological, osteological and nail nature, as well as traces of sperm, blood, saliva. The chosen research topic is strictly topical since biological traces represent a very common branch in forensic research. Daily life highlights the fact that the vast majority of criminal acts that were committed by violence left material evidence of the events at the scene, but the insufficient training in this field, as well as the lack of certain materials for strict analysis in finding and reporting the traces left behind on the spot, lead to the conclusion that there are situations in which some investigators do not observe in detail all the evidence, which hinders the investigation and finding out the truth, creating irreversible consequences both for the person involved and for the society in which we live.

 Currently, when we take part in the competition between criminalists and lawyers, as well as criminals, it can be highlighted that the benefits of a system that wants to be a democratic benefit, for the most part, the people in the area of delinquency, giving rise to numerous questions regarding the way in which forensic specialists, investigators, and magistrates are trained (Stancu, 2010, p. 8).

 The importance of the chosen theme resides in most of the difficulties encountered in practice due to lacunar legislation and doctrinal opinions, as well as the existence of a non-unitary jurisprudence.

 The chosen research topic aims to document the current state of knowledge and interpretation of biological samples of a biological nature, to perform experiments to be able to conclude investigative reports, as well as to identify uncertainties arising in forensic practice.
