摘要

在调查罪案现场时,检测潜在指纹的方法不断完善和加强。在实验室运输不可行的表面上实施粉尘技术通常会产生较低百分比的可识别指纹。这个问题主要是由于这些表面的固有特性和它们各自的污染水平。此外,实验室程序的应用,通常指定为氰基丙烯酸酯发烟法,对于在现场条件下有效地开发指纹至关重要。在这项研究中,五名捐赠者(三男两女)在日常生活中随手可得的材料上留下了自然指纹,如显微镜载玻片、粗糙和光滑的云母以及镀锌板。指纹分析在7个不同的时间间隔进行:1天、1周、1个月、3个月、6个月、9个月和12个月。使用的280个指纹每一个都被分成两个相等的部分,总共有560个指纹段供检查。本研究结果表明,用粉尘法提取的指纹鉴别率为52.9%,用氰基丙烯酸酯烟熏法提取的指纹鉴别率为89.3%,用氰基丙烯酸酯喷雾法提取的指纹鉴别率为95%。这些结果强调了氰基丙烯酸酯喷雾法作为解决刑事案件的重要科学技术的潜在意义。

An innovative approach to latent fingerprint development at crime scenes: The cyanoacrylate spraying methodology.

The methods employed to detect latent fingerprints during crime scene investigations are continually refined and enhanced. The implementation of dusting techniques on surfaces that are unfeasible for laboratory transport often yields a lower percentage of identifiable fingerprints. This issue is predominantly due to the inherent properties of these surfaces and their respective levels of contamination. Furthermore, the application of laboratory procedures, typically designated for the cyanoacrylate fuming method, is of paramount importance for efficient fingerprint development in field conditions. In this study, five donors (three males and two females) deposited natural fingerprints on readily available materials in day-to-day life, such as microscope slides, both rough and smooth mica, and galvanized sheet metal. The analysis of fingerprints was conducted at seven distinct time intervals: 1 day, 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months. Each of the 280 fingerprints used was divided into two equal parts, resulting in a total of 560 fingerprint segments for examination. The findings of the current study showed that 52.9% of fingerprints suitable for identification were developed with the dusting method, 89.3% with the cyanoacrylate fuming method, and 95% especially with the cyanoacrylate spraying method. These results underscore the potential significance of the cyanoacrylate spraying method as an essential scientific technique in the resolution of criminal cases.
