ABSTRACT:
Like most other areas of Forensic Science, bloodstain pattern evidence interpretation is characterized by the overlap from various other fields of science such as physics, computer science, medical science etc. For example, fluid mechanics particularly explains the forces that lead to the formation of a particular bloodstain pattern. Forensic Medical practitioners particularly work towards drawing the correlation between the bloodstain patterns formed and the wound formed on the body or head of the victim concerned. The paper studied hammer transfer stains in particular because of the easy availability and usability of hammer round the world. Also we studied effect of stain pattern in the crime scene. The authors are of the view that of the different types of bloodstain patterns, the most common stain patterns visible at the crime scene, particularly in the case where the victim is found to suffer blunt force injuries, are saturation, impact, cast off and transfer stain patterns.
