The association of victim-offender relationship and the achievement of hits in DNA database, a portrayal from the Central of Brazil

Recent advances in forensic biology and forensic DNA typing: INTERPOL review 2019–2022

“…From 275 previously untested sexual assault kits submitted for DNA testing in one region of Central Brazil, a total of 176 profiles were uploaded to their DNA database resulting in 60 matches (34%; 60/176) and 32 assisted investigations (18%; 32/176) with information about the suspect identity or the connection of serial sexual assaults assigned to the same individual [ 135 ]. Another study from the same region of Brazil examined 2165 cases and noted that 13% (286/2165) had information regarding the victim-offender relationship with 63% (179/286) being stranger-perpetrated rapes and 37% (107/286) being non-stranger [ 136 ]. The authors then summarize: “Hits were detected only with stranger-perpetrated assaults ( n = 41), which reinforces that DNA databases are fundamental to investigate sexual crimes.…”
