DNA Forense: Desvendando Crimes através da Análise de Vestígios Biológicos e Contribuições do Banco de Perfis Genéticos"

Abstract

Forensic science, a network of investigation that analyzes material evidence, linking suspects to crime scenes. The team, composed of forensic experts with different academic backgrounds, conducts meticulous experiments, ensuring the integrity and traceability of the evidence. The recording and documentation of these samples must be thorough, strengthening the chain of custody and ensuring the admissibility of the evidence in court. This work aims to show the importance of biological traces such as blood, saliva, semen, hair strands, and others for solving crimes, supported by the national structure of the Integrated Network of Genetic Profile Databases. For the writing of this work, national and international articles related to the topic, such as solved crimes, traces, and their particularities, were selected. Through the network and its published semi-annual reports, we observe effective results in solving crimes where the perpetrators were brought to justice and convicted for the committed crime. The results obtained and demonstrated in the RIBPG reports show its great utility in strengthening the body of evidence by inserting data into state and national databases, obtaining a large number of matches and aided investigations. Goiás appears among the top five states that contribute the most to the growth of the network, feeding the database in all categories, achieving positive results.
