The identification of decomposed corpses found in domestic settings is frequently problematic because comparative material for methods such as forensic odontostomatology, comparative X-ray analysis, or DNA analysis, is not available. In the case presented here, a photograph from an old, expired passport could be used to successfully identify a "domestic setting" corpse in a skull-photo superimposition. In an additional DNA analysis, 13 STR-loci could be amplified from tissue samples taken from the corpse. DNA comparison with the presumed brother of the deceased yielded a probability of 97.09% for siblingship. Y-STR-analysis was, therefore, performed. The results showed that all of the systems for the presumed brother and the corpse conformed, with the exception of the DYS390 locus, in which allele 21 was found for the corpse and allele 22 for the brother. Despite the rapid development of other identification procedures, skull-photo superimpositions remain an important means of identification. Last not least this is due to the increasing ubiquity of personal photo documents in the age of digital photography. The validity of the results from a DNA analysis in an identification process depends largely on the authenticity of the samples available for comparison and the degree to which the DNA from the corpse is preserved. In the case presented by the authors, positive identification of the corpse solely on the basis of the DNA analysis would not have been possible. Numerous constellations can be imagined for decomposed corpses found in domestic settings for which skull-photo superimpositions may be the only possible option for identifying the corpse.
在家中发现的已腐烂尸体的身份鉴定常常存在问题,因为诸如法医口腔学、X射线对比分析或DNA分析等方法所需的对比材料并不具备。在本文所述案例中,一本过期旧护照上的照片被成功用于颅骨照片叠加比对,从而鉴定出一具“家中发现的”尸体。在进一步的DNA分析中,从尸体提取的组织样本成功扩增出13个STR基因座。与死者推定的兄弟进行DNA比对,得出两人为同胞关系的概率为97.09%。因此,又进行了Y-STR分析。结果显示,除DYS390基因座外,推定兄弟与尸体的所有系统均相符,在该基因座中,尸体样本检测到等位基因21,而其兄弟样本检测到等位基因22。尽管其他鉴定程序发展迅速,但颅骨照片叠加比对仍是重要的鉴定手段。这尤其归因于在数字摄影时代个人照片文件的日益普及。在身份鉴定过程中,DNA分析结果的有效性很大程度上取决于用于比对的样本的真实性以及尸体DNA的保存程度。在作者所举案例中,仅基于DNA分析无法确定尸体身份。对于在家中发现的已腐烂尸体,可设想出无数种情况,而颅骨照片叠加比对可能是鉴定此类尸体的唯一可行方法。
