Abstract

A considerable range of techniques is available to visualise latent fingerprints on smooth surfaces. Published methods and those developed or modified in the authors' laboratory have been evaluated for spent cartridge cases. The most suitable were found to be vacuum cyanoacrylate (with fluorescent staining) and selenious acid treatments. Both were used to investigate the post firing recovery of finger-marks on spent cartridge cases from the ammunition and weapon systems encountered in terrorist casework in Northern Ireland. Only certain revolvers and the SLR rifle yielded identifiable ridge detail. These results are borne out by casework experience.

摘要

有相当多的技术可用于显现光滑表面上的潜在指纹。已对已发表的方法以及作者实验室开发或改进的方法进行了用于用过的弹壳的评估。发现最合适的是真空氰基丙烯酸酯（荧光染色）和亚硒酸处理。这两种方法都被用于调查北爱尔兰恐怖主义案件工作中遇到的弹药和武器系统用过的弹壳上射击后指纹的恢复情况。只有某些左轮手枪和SLR步枪产生了可识别的纹路细节。这些结果得到了实际办案经验的证实。
