伴随着现代科技的不断发展,犯罪嫌疑人的反侦查能力逐渐增强,在犯罪现场很难搜集到常量物证,因此,微量物证逐渐被广泛运用于现场勘查中,由于微量物证具有涉及范围广、依附性强等特点,再加上不易被犯罪嫌疑人所发现、不易消失、毁灭等因素,能更好的为打击违法犯罪提供重要依据,确定侦查方向,缩小侦查范围。在现场勘查中,微量物证的采集和包装是非常重要的,不同种类的微量物证的采集和包装方法也不近相同,本文就微量物证的采集和包装方法及其注意事项做了详细的阐述。
With the continuous development of modern science and technology, the suspects’ ability of anti-detection is gradually enhanced. It is difficult to collect constant evidences at the crime scene. Therefore, trace evidences are gradually being widely used in on-the-spot investigation. Since trace evidences have a wide range of scopes, Strong and other characteristics, coupled with not easily found by suspects, not easy to disappear, destruction and other factors, can better provide an important basis for cracking down crimes, determine the direction of investigation, to narrow the scope of the investigation. In the field investigation, the collection and packaging of trace evidences are very important. The collection and packaging methods of trace evidences of different kinds are also not nearly the same. This article elaborates the methods of collection and packaging of trace evidences and their precautions.
