Identificação de suspeitos de casos de abuso sexual

Abstract

Deoxyribonucleic acid (DNA) plays an extremely important role in cases of sexual crimes, where 40% of traces can be examined. For good care of the victim, a complete and agile care protocol is recommended, avoiding revictimization. Samples collected and analyzed in criminal cases are entered into the integrated network of genetic profile banks (RIBPG) and the national genetic profile bank. This work aims to demonstrate the results of identifying suspects by comparing profiles generated by official laboratories in Brazil with profiles of convicts, crime scenes, missing people and references. The use of molecular markers is essential for elucidating crimes and human identification, with STRs markers being most used for forensic DNA testing. The genetic data generated is stored in a database and compared with each other, looking for coincidences, identifying perpetrators in criminal investigations. The integration of RIBPG laboratories is fundamental for resolving sexual crimes, missing persons, interstate and old cases, serial and international crimes. Examples of criminal case solutions from all categories are demonstrated in real cases. It is observed that the methodology using advanced techniques provides accurate and reliable results, strengthening material evidence in the criminal process. In this way, data obtained from the use of the genetic profile bank supports the reduction of the feeling of impunity in our country.
