名噪一时的美国“辛普森案”以及闹得沸沸扬扬的美国总统克林顿与莱温斯基的桃色新闻,使 DNA 技术给广大公众留下了极其深刻的印象。实际上,自1985年英国科学家简夫瑞博士首先将 DNA 指纹技术应用于1例移民案件的亲子鉴定后,DNA 技术在为刑侦提供线索,为审判提供证据方面已起到了决定性的作用。国内方面,DNA 技术在中国法医学领域的应用也走过了十余年的艰苦历程,经过我国法医工作者的不断努力,DNA 鉴定技术在我国刑事侦破领域(如强奸案、碎尸案、网上打拐等)及民事鉴定领域(如亲子鉴定等)的应用也日臻成熟。其中华西医科大学法医学院物证教研室的DNA 指纹研究水平在国内居领先水平。这里我们通过1例案件,来介绍 DNA 指纹技术的巨大威力,同时也让读者对这项高新技术有些初步了解。死者是谁1999年3月27日,在四川一个偏远的小山村,几个调皮的孩子打闹着进入了山后一座废弃的窑洞中,展现在他们眼前的
The notorious U.S. Simpsons case and the nascent blushing news of U.S. President Bill Clinton and Lewinsky made DNA technology extremely impressive to the general public. In fact, DNA technology has played a decisive role in providing clues to criminal investigation since it was first applied by British scientist Jane Frye to DNA paternity testing in 1985 in a case of immigration. Domestically, the application of DNA technology in the field of forensic science in China has also gone through more than ten years of hard work. Through the constant efforts of forensic workers in our country, DNA identification technology has been widely used in criminal detection areas such as rape case, Etc.) and civil applications (such as paternity testing, etc.) are also becoming increasingly sophisticated. Among them, the forensic teaching and research office of Huaxi Medical University Forensic Medical College has the leading level of DNA fingerprint research in China. Here we pass a case to introduce the great power of DNA fingerprinting, but also allow readers to have some preliminary understanding of this high-tech. On March 27, 1999, in a remote small mountain village in Sichuan province, a few naughty children slapped into an abandoned cave behind the mountain and showed them in front of them
