在一起重大盗窃案现场中,我们提取了一枚犯罪分子的手印(见附图),经初步检验认为现场指纹纹形为双箕斗。根据遗留的部位,纹线的流向,定为右手拇指所留,通过排查,密取了重大嫌疑人李××右手拇指指纹(见附图),并与现场拇指纹进行了比对检验。在检验中发现李××拇指指纹为绞形斗。显然两者出现了“本质”差异。对此我们又重新对现场手印进行深入分析检验。现场指纹系用铝粉显现,但印痕左、右两部分对粉末的吸附能力不同。它突出的表现在左侧吸粉强而纹线不清;右侧吸粉弱但纹线清晰;同时分析花纹印痕向左倾斜的纹线,其左侧未出现三角,但右侧三角 In the scene of a major theft, we extracted a fingerprinting from criminals (see the attached figure). After a preliminary examination, we found that the fingerprint pattern on site was double-skip. According to the left part, the direction of the ridge lines, set for the right thumb left, through the investigation, close the big suspect Li × × right thumb thumbprints (see photo), and with the thumb in the field of comparison test. In the test found that the thumbprint of Lee × × thumb-shaped bucket. Obviously there is a difference between the two “essences.” In this regard, we again on-site fingerprinting in-depth analysis test. The spot fingerprinting is made of aluminum powder, but the left and right parts of the impression have different adsorption capacities for the powder. It highlights the strong suction on the left side of the strong wind and clear lines; the right side of the weak weak aspirated dust; at the same time analyze the pattern imprinted sloping lines to the left, there is no triangle on the left, but the right triangle
