现场勘查中,我们经常遇到水中浸泡的无名尸体,这类尸体有的是被害后投入水中,有的是溺水死亡。由于水的长时间浸泡,尸体腐败,头面部呈巨人观状,无法辨认。能提取尸体的指纹这对查找尸源,侦破案件是十分重要的。然而,水中浸泡的尸体手指表皮大多已油脂化,手指皮肤表皮与真皮脱落,形成了人手表皮手套,按正常捺印指纹的方法是无法捺印出理想的指纹的。实践中,我们根据有关资料的介绍,采用人手表皮手套反向捺印的方法,取得了较好的效果。具体分三步进行:第一步用剪刀、镊子在尸体手上将表皮镊住,剪下要捺印的部位,放入托盘中。用酒精棉球擦去表皮上的水分,晾至半干状态。同时记录是哪个指位。第二步准备好捺印的油墨、纸张,用剪刀剪去指甲将表皮翻转过来,沾上油墨捺在纸上,即可捺出皮肤内侧的纹线花纹。第三步将捺印出的纹线花 During the scene investigation, we often encountered unknown bodies soaked in water. Some of these bodies were put into the water after they were killed and some died as a result of drowning. As the water soaked for a long time, the body corrupt, the head and face were giant view, can not be identified. Can extract the body of the fingerprint This is to find the corpse source, detection of cases is very important. However, most of the fingers of the body soaked in water are already lipidated, and the epidermis of the finger skin and the dermis fall off to form a human wrist leather glove. The normal fingerprint printing method is unable to print an ideal fingerprint. In practice, according to the introduction of relevant information, we adopted the method of reverse printing on human wrist leather gloves and achieved good results. Specifically divided into three steps: The first step with scissors, tweezers in the hands of the skin will tweezers, cut to suppress the site, into the tray. Wipe the water on the epidermis with alcohol cotton balls, dry to semi-dry state. At the same time record which finger position. The second step is to print the stamping ink, paper, cut the nails with a scissors flip the epidermis, stained with ink on the paper, you can get out of the inner lines of the skin pattern. The third step will be printed Na Wen line flowers
