The species identification of botanical stains from a suspect’s clothes using plastid DNA markers for a criminal case
This case report handled the comparative sequence analyses of plastid DNA markers acquired rom botanical stains of a suspect’s clothes and a sickle which were the items of criminal evidence in agricultural property damage case. Three victims found out that their cherry tomatoes in green houses of the width of about 5,950 square meters were cut off. For the forensic botanical analysis, the police requested a suspect’s clothes, cotton gloves, two sickles, gauzes and cotton swabs collected by wiping a suspect's motorcycle and car. Cherry tomato plants from victims’ green houses as positive controls were received. The nucleotide sequences of plastid trnL-trnF IGS and psbA-trnH IGS regions from evidences were compared with positive controls and with DNA databases in GenBank of National Center for Biotechnology Information (NCBI). According to nucleotide sequence results, the lower part of suspect’s training wear got stained with tomato substances, the upper part with kiwifruit. The wooden handle of a sickle of a suspect showed the apricot nucleotide sequences. Gauzes, cotton swabs, two gloves, two pants and other sickle showed no results by plastid DNA markers. Plant stains from clothes and wooden materials or wood itself can be genetically analyzed for the elucidation of criminal cases.

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.
