摘要
指纹检验技术是侦破案件的重要手段之一,因此指纹提取在现场勘查中具有重要作用。本文基于全国公安机关现场勘验检查系统和指纹自动识别比对系统,对自2010年1月1日至2014年12月31日期间,在辽宁省东港市发生的十类刑事案件中的现场指纹进行统计与分析。在十类刑事案件中,以入室盗窃案件为主,故其现场遗留指纹数量最多;现场常见客体以硬、光滑客体为主,显现常采用粉末法;现场指纹多为右手所留,且集中于拇指、食指和中指;在302枚现场指纹中,有101枚认定82名犯罪嫌疑人,正查比中的前科人员占67%,指纹留档2次以上的人员占76.4%。随着指纹自动识别系统的快速发展,指纹检验技术将会在侦查破案中发挥更大作用。
Fingerprint identification is of importance to identify suspects. Therefore, collecting fingerprints at crime scenes is crucial for crime scene investigation. Based on the data from Crime Scene Investigation System（CSIS） and Automated Fingerprint Identification System（AFIS）, the statistical analysis was carried out on the fingerprints collected at crime scenes in the city of Donggang, Liaoning province of China from January 1st, 2010 to December 31 st, 2014. Home burglaries took up the major part in the counted criminal cases, thereby leaving the most of fingerprints to be found and collected. Powder method was often used by the local police to develop latent fingerprints which were mainly left by right hand, primarily of its thumb, fore- and middle fingers, on non-porous hard and smooth surfaces. Of the 302 fingerprints collected at crime scenes, 101 ones resulted in having identified 82 suspects, among whom 67 %（55 persons） were matched by AFIS as these people have criminal records and even about 76.4 % of them were recorded for two or more times. With the rapid development of AFIS, fingerprint identification will play a more important role in identifying suspects in the future.
