Despite progress in methods of scientific investigation, the increasing number of unidentified cadavers is a growing problem world-wide. We performed detailed statistical analysis based on reported data for Japanese JC virus (JCV) genotype distribution, and obtained two curves showing a marked north-south difference in the JC viral genotype, in spite of the frequent movement of people in Japan. This suggested the possibility of determining the origin of unidentified cadavers numerically, thus making the police investigation of unidentified cadavers much more economical and efficient. If the distribution of JC viral genotypes could be investigated in detail, it would be possible to obtain geographic information about unidentified cadavers even in a certain area.
尽管科学调查方法取得了进展，但身份不明的尸体数量不断增加是一个在全球范围内日益严重的问题。我们根据日本JC病毒（JCV）基因型分布的报告数据进行了详细的统计分析，尽管日本人流动频繁，但得到的两条曲线显示JC病毒基因型存在明显的南北差异。这表明有可能从数字上确定身份不明尸体的来源，从而使警方对身份不明尸体的调查更加经济高效。如果能够详细调查JC病毒基因型的分布，即使在某个特定区域，也有可能获得身份不明尸体的地理信息。
