不同承载客体手印的显现

Fingerprint Development on Different Carrying Objects

人手表面的乳突纹线、屈肌褶纹、皱纹等皮肤花纹结构在力的作用下接触客体时所形成的能反映花纹结构与外形结构特点的印痕称为手印。利用客体上遗留的手印进行同一认定可以认定遗留者,但是在大部分的犯罪案件现场,由于承载客体的的不同性质造成手印的纹线断纹、残缺和变形,给手印进一步的分析判断工作造成了一定的困难。比较各种显现方法在不同承载客体遗留手印的显现效果,针对不同承载客体采取适当的显现方法以期达到最佳效果,以使犯罪案件现场的手印能够有效提取,使其发挥有力的证据作用,为实际公安工作中显现不同承载客体的手印提供一定的思路。

Fingerprints are prints of pattern structure and shape structure left from papillary ridge, flexor crease, wrinkles and other skin pattern structure of hand surface to carrying objects under the action of force. The use of fingerprints left on the object were found to identify the same person, but in most cases on the crime scene, broken-lined, incomplete and deformed fingerprints due to the different nature of carrying objects make it difficult to conduct further analysis. This article compares various effects to develop fingerprints on different carrying objects by varying methods to achieve the best results so that fingerprints can be extracted effectively on the crime scene as strong evidence and provides new concept for actual police work.
