The Sexual Crime Evidence Backlog Project was conceived by the Steering Committee of the Integrated Network of Genetic Profile Databases, which directed investments to provide equipment and supplies to Brazilian states that had established goals for processing their backlogs related to sexual crimes. The Forensic Molecular Genetics Laboratory (LGMF) of the Scientific Police of the State of Paraná committed itself to processing two thousand pieces of evidence from its backlog and was therefore provided with the automated ID STARlet Hamilton platform. Evidence from sexual crimes that occurred between 2010 and 2021, involving approximately 900 victims, was processed. Differential lysis was performed manually, while purification and the remaining stages were carried out using the ID STARlet Hamilton platform. In less than one year after the installation of the equipment provided by the National Secretariat of Public Security, the LGMF completed the processing and analysis of the two thousand pieces of evidence initially proposed. As a result, 786 male genetic profiles were uploaded to the National DNA Database (BNPG), resulting in 350 observed matches involving 196 victims. Furthermore, the intersection of these matches generated 79 Match Report Certificates, including matches with other states, convicted individuals, identified suspects, and cases still without suspects. The Sexual Crime Evidence Backlog Project enabled a significant expansion of the Genetic Profile Database of the Scientific Police of Paraná, which ranked third nationally in the absolute number of evidence profiles uploaded to the BNPG in 2021.
