Investigative Genetic Genealogy (IGG) has opened up new frontiers in the search for the perpetrators of serious crimes. The pool of data held by consumer DNA databases has enabled law enforcement agencies to undertake database matching to find biological relatives of an unknown perpetrator. This relatively new forensic practice is not, however, without concerns when benchmarked against established norms of investigative practice and criminal procedure. The critical questions emerge: how should IGG be used and in what circumstances? In this article, we contend that the current laws in Australia are not capable of regulating IGG appropriately and legislative reform is required.

研究性遗传家谱（IGG）在寻找严重犯罪者方面开辟了新的领域。消费者DNA数据库拥有的数据池使执法机构能够进行数据库匹配，以查找未知犯罪者的亲属。但是，当以既定的调查实践和刑事诉讼规范为基准时，这种相对较新的法证实践并非毫无顾虑。出现了关键问题：应如何使用IGG？在什么情况下应使用IGG？在本文中，我们认为澳大利亚的现行法律不能适当地调节IGG，因此需要进行立法改革。
