초록
현장에서 혈흔지문은 중요한 증거물이며, 테이프를 사용하는 범죄들도 많다. 이에 따라 본 실험은 테이프에 유류된 희미한 혈흔지문에 대해 단백질 염색 시약인 Amido black, Coomasie blue, Crowle's stain, Acid violet 17, Hungarian red 시약들의 증강효과를 자주 이용되는 5가지의 테이프(덕 테이프, 청 테이프, 투명 테이프, 황 테이프, 절연테이프) 별로 1:1 비교해 보았다. 혈흔 지문은 각 테이프별로 10차례 순차적으로 유류 시킨 후 실온에서 4시간 건조 시킨 뒤 10번째로 찍힌 희미한 지문만을 사용하였다. 덕 테이프에서는 Amido black과 Coomasie blue, Hungarian red가 우수한 결과가 나왔으나 그 중 Hungarian red가 가장 우수하였다. 청 테이프에서는 Amido black과 Coomasie blue, Hungarian red 모두 우수한 것으로 나왔으며, 투명 테이프에서는 Coomasie blue와 Hungarian red가 우수 하였으며 Hungarian red가 가장 우수하게 현출하였다. 황 테이프에서는 Amido black과 Hungarian red가 우수하였으며 역시 그 중에서 Hungarian red가 가장 우수하였고, 절연테이프에서는 5종의 시약이 모두 좋은 현출을 나타내었으나 Amido black과 Hungarian red가 가장 우수하였다. 결과를 종합하여 보면 테이프의 배경색이나 테이프의 종류에 상관없이 Hungarian red가 가장 좋은 지문을 현출해 내었으며, 배경에는 염색이 되지 않고 혈흔지문에만 염색이 되는 것을 관찰할 수 있었다.
Abstract
At the crime scene, bloody fingerprints are important evidence, and there are a lot of homicide cases using tapes. In this study, we compared the enhancement effect of Amido black, Coomasie blue, Crowle's stain, Acid violet 17 and Hungarian red on faint bloody prints which were deposited on the adhesive sides of five type tapes(duct tape, green tape, transparent tape, yellow tape and insulating tape). Bloody fingerprints were deposited sequentially 10 times and dried for 4 hours. On the duct tape and green tape, Amido black, Coomasie blue and Hungarian red were highly effective and among them, Hungarian red was the best. On the transparent tape, Hungarian red was more effective and on the yellow tape, Amido black and Hungarian red were very effective. Although all reagents were great effective on the insulating tape, Amido black and Hungarian red were the best. In conclusion, Hungarian red was the best enhancement reagent regardless of kinds or color of tapes and we confirmed that Hungarian red dyed only bloody fingerprints not background of tapes.
