现代生活中玻璃制品随处可见,在案件现场中玻璃也是一种常规的载痕体,如入室盗窃案中的门窗上、汽车盗窃案中的车窗上均容易留下潜在或可见的指印痕迹。现代犯罪分子一般都具备一定的反侦查意识,进入中心现场后往往戴有手套,很少留下指印痕迹;而在攀爬和撬窗中,由于外围性和戴手套的不方便,往往不戴手套,较容易留下指印痕迹。因此如何提取玻璃上的指印痕迹,往往成为勘查和侦破案件的关键。本文主要介绍了用综合提取方法,有效提取一枚玻璃载体上汗液、油脂的混合指印的过程。
Glass can be seen everywhere in the modern life. In the scene of the case, the glass is also a conventional carrier mark. For example, doors and windows in the burglary case can easily leave latent or visible fingerprints on the windows of a car theft. Modern criminals generally have some sense of anti-investigation. They usually wear gloves after entering the scene of the center, and rarely leave fingerprints on them. In climbing and prying windows, they often do not wear because of the externalities and the inconvenience of wearing gloves Gloves, fingerprints easier to leave marks. Therefore, how to extract fingerprints on glass often becomes the key to the exploration and detection of cases. This paper mainly introduces the comprehensive extraction method, the effective extraction of a glass carrier on the sweat, grease fingerprinting process.
