手印的特性决定了其在法庭证据中的地位,它用来直接认定嫌疑人,为侦查破案提供依据。刑事科学技术的发展使手印检验技术得到了广泛应用,但在我们实际工作中,由于多种因素的影响,很多刑事案件现场提取到的手印大多是模糊不清的、残缺不全的、或重叠变形的。本文对此类疑难手印特征的寻找与判定进行了总结,希望能够对手印鉴定工作者提供参考。
The characteristics of fingerprints determine its position in forensic evidence, which is used to directly identify suspects and provide basis for investigation and detection. The development of criminal science and technology has made handprint inspection technology widely used, but in our practical work, due to many factors, many handprint prints extracted from criminal cases are mostly vague, incomplete or overlapping of. This article summarizes the searching and judging of these difficult handprint features, and hopes to provide a reference for handprint authentication workers.
