【摘要】：Y染色体是男性特有的染色体,可用于判定父系遗传。以Y染色体遗传规律为基础,公安机关已建立了Y-STR家系种类排查方法,用以划定侦查范围、确定犯罪嫌疑人所在的家系。一般而言,Y-STR家系排查主要应用于封闭区域,具有良好的甄别作用,可有效提高办案效率,在开放性地域中应用作用有限。本文报道了一起发生在江苏省苏州市某地的恶性杀人案件,该案件的侦破中应用Y-STR技术确定犯罪嫌疑人籍贯,缩小侦查范围并最终破案,为建立一种Y-STR应用新模式提供了启示。
[Abstract]:The Y chromosome is a male-specific chromosome that can be used to determine patrilineal heredity. Based on the genetic law of Y chromosome, the public security organs have established a method for sorting Y-STR families to delineate the scope of investigation. Generally speaking, the screening of Y-STR families is mainly used in closed areas and has a good screening effect, which can effectively improve the efficiency of handling cases. This paper reports a malignant homicide case in Suzhou, Jiangsu Province, in which Y-STR technique was used to determine the origin of the suspect, to narrow the scope of investigation and to solve the case. It provides inspiration for the establishment of a new model for the application of Y-STR.
