초록
현장 수사에서 사후경과시간(PMI-min)을 추정하는 것은 용의자를 추정하거나 신원확인 등 법의학과 현장 실무에서 중요한 업무 중 하나다. 사후경과시간을 추정하는 방법에는 사후체온변화, 시반, 시강, 위 속 내용물의 소화 및 초생체 반응 등 여러 가지가 존재하지만 정량화하는 데에 한계가 있고, 부패 이후에는 적용이 어려운 한계가 있다. 본 연구에서는 2019-2020년 충청북도지방경찰청 관할 지역 내에서 발생한 총 25건의 변사 사건의 시신에서 채취한 법곤충학적 증거물을 활용하여 최소 사후경과시간을 추정하였으며, 연구결과는 수사기록상의 마지막 행적 결과와도 배치되지 않음이 확인되었다.
Abstract
Estimation of postmortem interval (PMI-min) in crime-scene investigations is one of the important tasks in forensic science and field practice, such as estimating suspects or identification. Although there are many methods of estimating postmortem interval, such as body temperature change after death, livor mortis, rigor mortis, digestion of stomach contents, and supravital reaction, but there are limitations in quantifying them, which are difficult to apply after decomposition. In this study, the minimum postmortem interval was estimated using forensic entomological evidences collected from a total of 25 corpses within the jurisdiction of Chungbuk provincial police agency between 2019 and 2020. It has been confirmed that the results do not conflict with last track record.
