[The value of skull-photo superimpositions in identifying corpses found in domestic settings]

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.
