Abstract
Background: DNA profiling plays a vital role in the identification of dead bodies during mass disasters. Severe fragmentation, decomposition, burning and intermixing of the remains can occur in the mass disasters. DNA analysis faces many challenges especially when the dead bodies are completely decomposed or burnt. This report presents the identification of 32 completely burnt individuals including three families from their remains in a bus using AmpFlSTR Identifiler Plus® Kit and AmpFlSTR Y-filer® Kit.
Methods: DNA was extracted from provided remains of burnt bodies and reference samples by organic extraction procedure. The extracted quantity of DNA was calculated on ABI SDS7500 real time PCR with Quantifiler® Human DNA Quantification Kit (Applied Biosystems). DNA samples of 32 completely burnt individuals including three families were amplified using AmpFlSTR Identifiler Plus® Kit and AmpFlSTR Y-filer® Kit. The genotyping of these amplified samples was performed on ABI 3130xl Genetic Analyzer.
Results: The resulting data obtained from Genetic Analyzer was analyzed using GeneMapper ID software version 3.2 (Applied Biosystems). Seventeen burnt individuals including 3 burnt families were identified with the help of 16 autosomal STRs and 6 were identified through Y-STR analysis by allele sharing of their provided reference samples of parents and brothers respectively.
Conclusion: For the identification of unknown individuals particularly burnt deceased victims, STR analysis has become the gold standard in forensic science. Successful DNA profiling through the amplification of STR markers of AmpFlSTR Identifiler Plus® Kit proved to be very helpful in identifying the remains of burnt individuals even in the presence of inhibition observed in the Real Time PCR.
