1996年,在某地发生一起作案者挖洞进入仓库盗窃物品的案件,笔者在勘查现场时,发现几片半新的玉兰树叶,经分析认为可能是作案者利用它们来使其指纹不留在地面上,故认定树叶上可能留有作案者的指纹。对树叶进行指纹显现:首先,用常规的植物花粉撒粉吹显法进行显现,取得了一定的效果(见图1)。笔者对剩下的树叶利用金粉来进行显现,亦取得了较好的效果(见图2)。为此,笔者对树叶上汗潜手印的显现作了进一步的探讨、实验。 In 1996, there was a case of a burglar digging into a warehouse for theft of goods in a certain place. When I surveyed the site, I found a few new leaves of magnolia, which were supposedly used by criminals to make their fingerprints remain On the ground, it is assumed that there may be fingerprints on the leaves. Fingerprints on the leaves show: First of all, the conventional plant pollen flour blowing method was developed, and achieved some results (see Figure 1). The author of the remaining leaves to use gold to show, but also achieved good results (see Figure 2). To this end, the author of the sweat latent fingerprints on the leaves made further discussions, experiments.
