Abstract

This study was carried out to offer the forensic entomological evidence to estimate the postmortem interval (PMI) based on the decomposing state of the pig carrion and the arthropod succession in exposed carrion. A total of 48 species of 28 families belonging to 7 orders were collected, and dominant insect varied with season, i. e., the Calliphoridae in March, May and October, both of the Calliphoridae and the Staphylinidae in July, and the Staphylinidae in September. The Calliphoridae was the first visiting insect throughout all the seasons as well as the index insect dominant in the early decomposing stage. The index insect in the later decomposing stage, however, was the Staphylinidae throughout all the seasons except in March. In March, the Muscidae was dominant, presumably because the flies consistently arrived throughout the extended period of decomposition of the carrion owing to the low ambient temperature of the season. In this connection, it is known that not only the decomposition stage of the carrion and the carrion-associated insect but also the climatological condition of the region have to be taken into consideration to estimate the PMI.

본 연구는 집돼지 사체주위에서 채집되는 곤충의 천이패턴을 이용해서 사체의 사후경과시간을 추정하기 위한, 법의학적 증거모델을 제시하고자 수행되었다. 사체의 주변에서 총 7목28과 48종의 곤충이 채집되었는데, 계절에 따라 많이 나타나는 곤충이 변하여 3월, 5월 및 10월에는 검정파리과가, 7월에는 검정파리과와 반날개과가 같은 비율로, 9월에는 반날개과가 많이 관찰되었다. 검정파리과 곤충은 모든 실험을 통해서 사체에 가장 먼저 도착하는 곤충이며 또한, 부패초기의 지표곤충임이 밝혀졌다. 그러나 부패후기의 지표곤충은 3월을 제외한 나머지 연구기간 중에는 반날개과, 3월에는 집파리과였는데, 3월에는 낮은 온도로 인해서 사체 부패 기간이 오랫동안 지속되었으므로 사체 주위에 모여든 집파리과의 개체수도 증가한 것으로 생각되었다. 이상으로부터 사체의 사후경과시간을 유추하기 위해서는 사체의 부패 정도나 사체 주변에 나타나는 곤충 뿐 아니라, 조사 지역의 기후 조건도 고려해야 할것으로 생각되었다.
