총기 사고에서 중요한 감정분야 중 하나인 탄피흔적 시험법을 확립하고자 쌍안비교현미경의3D 다초점 기능을 이용하여 탄피흔적 중 격침흔 계측방법 및 식별 기준을 제시하였고 CAL-45 권총 1 정과 K-2 소총 4정을 이용하여 각각의 총기로 10회씩 발사된 탄피시료에 대하여 계측법을 적용하여 유사율을 확인하였다. 또한, CAL-45 권총과 K-2 소총으로 발사된 탄피시료에 대한 계측값의 유사율을 비교함으로써 탄피의 흔적감정 시 동일 총기에서 발사되었는가에 대한 판단기준으로서의 적합성을 확인하였다. K-1A 소총과 K-2 소총에서 발사된 탄두 강선흔의 기울기를 측정 비교한 결과, 두 소총간의 강선흔 기울기는 약 2도 이상 차이 남을 확인 할 수 있었다. 본 연구를 통하여 총기 발사흔 계측 데이터를 통계적으로 분석하여 기존의 총기 발사흔 감정 시 식별과정 표현의 난해함이 해소될 것으로 생각되며 향후 총기발사흔 감정에 대한 신뢰성 있는 실험과 데이터베이스 구축의 기반이 되었다.
Abstract
To establish a method of examining the impressions on cartridge cases, one of the most important areas of examinations in firearm accidents, measurements of firing pin marks and identification standards for analyzing impressions of cartridge cases are proposed through the use of 3D multi-focusing function of the binocular comparison microscope. Additionally, the degree of similarity has been verified by applying the measurements to the sample cartridge cases that has been fired once each by 1 CAL-45 pistol and 4 K-2 rifles. By comparing the similarity of measurements of the sample cartridge cases fired by both the CAL-45 pistol and K-2 rifle, the validity of the standard of judgment for determining whether a cartridge case has been fired from the same firearm has been verified. The slope angle of the rifling impression bullet marks of K-2 rifle are different(two degrees) from each other has been found that. Through statistical analysis of the measured data, this method diminishes the difficulty of expression that existed in the previous method of identifying shooting trace marks. Conclusively, this method serves as foundation for establishing a method of examination and a database for reliable and credible examination of shooting trace marks.
