Abstract

Blood is important evidence in many crimes like murder, rape, gang war etc. Blood and semen are mildly alkaline aqueous body fluid, which carries DNA. Every living thing has DNA, it’s every composition differentiate you from others. The interesting fact is that although 99.99% of human DNA sequences are same in every person it is only 0.01 % of DNA that makes you unique. According to Locard Principle it is impossible for a criminal to act especially considering the identity of a crime without leaving traces of his presence , that means whenever someone enters or exist an environment, something physical is added to or removed from the scene. In rape cases not only semen factor is important but also blood plays vital role in the forensic analysis. In some rape cases we observed that condoms are being used by accused, therefore in such cases it is quite impossible to get the analytical results of semen. Likewise in POCSO (protection of child from sexual offence.) rape cases analytical tests for semen resulted as negative as the victim passes out urine , in such rape cases “Blood “is the only important factor for analytical view. Sometime blood of victim is observed on clothes of accuse or vice versa. Analytical results of blood correlate the crime scene.
