A DIDACTIC APPROACH TO FORENSIC CHEMISTRY METHODS APPLIED IN CRIMINAL INVESTIGATIONS IN MARANHÃO

Abstract

Forensic Chemistry has assumed an increasingly relevant role in contemporary society, establishing itself as an important scientific tool in assisting the elucidation of criminal dynamics and the production of technical evidence to support police investigations and judicial proceedings. The present study aims to present a discussion, through an experience report, on the importance of forensic chemical methods applied to criminal investigations, especially in the context of the State of Maranhão, where different types of crimes demand increasingly effective technical and scientific responses. To this end, an experience report was conducted on the main forensic techniques employed in investigations carried out by the Civil Police of the State of Maranhão, emphasizing the analysis of physical and chemical evidence found at crime scenes, as well as the laboratory procedures used for the identification of substances and materials of forensic interest. The observed results demonstrate that, despite limitations related to infrastructure, resource availability, and the need for technological expansion, Forensic Chemistry plays a fundamental role in crime elucidation, contributing significantly to the identification of evidence, reconstruction of events, and strengthening of criminal investigations. Furthermore, its importance as an instrument to support justice is highlighted, promoting greater reliability in investigative processes and enhancing the effectiveness of public security actions.
