Forensic research. Skull and bones in a forensic laboratory. The bones have been numbered for identification. The researchers are trying to determine the identity of the body, which can be done by extracting and studying DNA. DNA (deoxyribonucleic acid) is the chemical responsible for heredity, and is different in each individual. These are the remains of someone abducted and murdered during the military rule in Argentina between 1976 and 1983. The hole in the skull is testament to a violent death. Photographed in Buenos Aires, Argentina.
