许多奸杀案中,警方已知罪犯是谁,但苦于没有直接证据,罪名便难以成立。今天终于有了令罪犯无可逃匿的科学证据,它就是——DNA指纹。在法医学上,物证是指作为行凶作案时使用的工具或保留有痕迹的物品,以及其它可能成为揭露罪行和发现凶手的资料。如人体某些组织器官、凶器、工具、衣物、血迹、指纹、足迹、气味、药物、笔迹、毒品、日常用品等。物证无论是在澄清事实、侦破案件上,还是在排除嫌疑对象,为被害人伸冤雪耻方面,都具有举足轻重的作用。随着高新科技的发展和应用,人类基因水平上的遗传多态性位点检测技术已被应用于法医物证的检查工作。这种被称为“DNA指纹”的检验技术,克服了血型检验在个体识别效率上的不
In many rape and murder cases, the police knew who the criminals were but found it difficult to establish the charges without direct evidence. Today there is finally scientific evidence that makes criminals unavoidable. It is - DNA fingerprinting. In forensic science, physical evidence refers to the tools used or the traces reserved for assault, as well as other information that could become a source of uncovered crime and the discovery of the murderer. Such as the human body some of the organs and organs, weapons, tools, clothing, blood, fingerprints, footprints, odor, drugs, handwriting, drugs, daily necessities and so on. Material evidence plays a decisive role both in clarifying facts, in detecting cases, in removing suspects and in victimizing victims. With the development and application of high and new technology, genetic polymorphism loci detection technology has been applied to the examination of forensic evidence. This is called “DNA fingerprinting” test technology, to overcome the blood test in the identification of individuals do not
