Comparative Analysis for STR Detection Rates in Groping-type Sexual Assault Case and Surprise Groping-type Sexual Assault Case in Busan, Ulsan, and Gyeongnam
According to the trends in crime occurrence and the characteristics of offenders, there is a reported downward trend in the overall number of crimes, while incidents of sexual violence crimes are on the rise. This increase in sexual violence crimes is presumed to be due to the rise in digital sex crimes and an the change in societal perceptions of sexual violence. Groping-type sexual assault constitutes the largest proportion of the sex crimes. Due to exaggerated media promotion recently, there are concerns that some cases may be misunderstood as applicable to the entire spectrum of incidents, leading to an increased perception that genetic analysis alone can resolve all groping-type sexual assault cases. In this study, the groping-type sexual assault cases with secured comparison samples of the suspects were selectively examined, and the detection rates of short tandem repeat (STR) and Y chromosome STR (Y-STR) DNA types in the surprise groping-type sexual assault cases were analyzed and compared to those of the groping-type sexual assault cases. The detection rates for STR DNA types in groping-type sexual assault cases and surprise groping-type sexual assault cases were similar, at 80% and 70%, respectively: however, the matching rates for the suspects' STR DNA types displayed a significant disparity, with 20% for groping-type sexual assault cases and 1% for surprise groping-type sexual assault cases. Furthermore, the detection rates of Y-STR DNA types for groping-type sexual assault cases and surprise groping-type sexual assault cases were 60% and 30%, respectively, with the matching rates for the suspects' Y-STR DNA types also showing a significant difference of 40% and 7%, respectively. It is more difficult to secure the suspect's DNA type in surprise groping-type sexual assault cases than groping-type sexual assault cases. Therefore, it should be recognized that genetic analysis alone cannot resolve all incidents.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
