초록
섬유는 사건·사고와 관련하여 가해자와 피해자 또는 사건현장과의 상호 관련성을 입증할 수 있는유용한 미세증거물이다. 섬유를 채취하는 가장 일반적인 방법은 전사테이프법으로 추가적인 시험을 위해서는 테이프에 부착된 섬유를 슬라이드 글라스 또는 금속판에 옮겨야 하는데 효율적인 방법에 대한 연구는미흡한 실정이다. 따라서 국내·외에서 활용되고 있는 섬유채취법을 토대로 섬유의 양상에 따른 효율적인채취법을 다음과 같이 검토하였다. 핀셋으로 집을 수 없는 미세 색상섬유는 투명점착판 분리채취법이 적합하였고, 비교적 큰 섬유의 색상섬유를 소량 채취할 경우 V형 절단채취법이 효율적으로 판단되었다. 다수의 큰 색상섬유는 점착면 개방채취법이 적합하였으며, 흰색계 섬유는 검정시트 활용 채취법이 효율적이었다. 이와 같이 전사테이프에 부착된 섬유의 크기 및 색상에 따른 적절한 채취법을 선택한다면 섬유 채취시간을 획기적으로 줄여 섬유증거물 분석의 용의성과 신뢰성을 높일 수 있을 것으로 판단된다.
Abstract
Fibers are useful trace evidence that can establish a connection between perpetrators and victims or crime scenes in incidents and accidents. The most common method of collecting fibers is tape-lifting, but there is a lack of research on efficient methods for transferring the fibers from the tape to a glass slide or metal plate for further examination. Therefore, based on fiber collection methods used domestically and internationally, efficient collection methods based on fiber types have been examined as follows: Small color fibers that cannot be picked up with forceps are suitable for the transparent adhesive film separation collection method; For a few relatively larger color fibers, V-cut collection method is efficient; For multiple large color fibers, the adhesive-face open collection method is appropriate; When collecting white fiber types, it seems to be efficient to use a black sheet background. By selecting the appropriate collection method based on the size and color of fibers attached to the tape, the time for fiber analysis during the collection process can be significantly reduced, thereby increasing the utility and reliability of fiber evidence.
