Abstract

Three DNA analysis methods; multiplex STR, Amplitype PM+DQA1 and mitochondrial DNA sequencing, were carried out for the personal identification of dismembered body parts. A fingernail sample of the right hand was successful in detecting all loci examined in the present case, however, on the other samples, one or more loci could not be analyzed in the PM+DQAl and multiplex STR. Mitochondrial DNA sequencing was successful in all samples. In the present case, the results were discarded unless all 6 loci in PM+DQAl and all 8 loci in multiplex STR were determined completely. However, obtained valid results should be utilized as much as possible. In cases of decomposed samples, there is no consensus among forensic biologists about the utility of detectable loci if some STR loci in multiplex STR are undetectable. Since multiplex STR is widely used in forensic casework on decomposed samples, beneficial criteria regarding the interpretation of the results should be established.
