ABSTRACT
The main objectives of biological evidence analysis are identification (or classification), individualization (DNA typing), and reconstruction. Classification of the evidence is determining whether it is blood, semen, or another bodily substance. Individualization of biological evidence is based on DNA typing, which is highly discriminating and has the power to attribute biological evidence to an individual with an extremely high degree of probability. Reconstruction of biological evidence is the interpretation of the pattern of the evidence, such as blood pattern analysis or the location of the semen stain with reference to the proposed crime scenario.
