Identification, Origin and Categorization of Blood from Different Rusted Iron Surfaces with respect to time for Forensic Consideration
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2017, Vol 12, Issue 4
Abstract
Blood is a highly complex mixture of cells, enzymes, proteins, and inorganic substances. Blood is one of the important biological evidence commonly encountered by the investigators at the scene of violence crime. Blood and blood stains are a very important entity in medico legal practices as factors like source of blood and their stains help in solving the crime of violence, accidental cases. This study was carried out at Sam Higginbottom University of Agriculture, Technology and Sciences, of Allahabad. In the present study, 3 different samples of blood were collected from central pathology lab and 6 different type of Iron samples were also collected from the local shops of Allahabad. The purpose of this study was for the identification of the changes in the characteristics of blood with respects to time. Precipitin test and benzedine test were carried out in the present study. Precipitin test was considered as an optimal test to determine the origin of species from blood. Different results were obtained. Thus it becomes essential to determine the sensitivity of blood stains on any surface. But in most cases of violence the presence of blood on the different rusted iron surfaces leads to false positive or negative tests which in turns results in no option by the experts. So it’s very necessary to examine blood which assists the forensic analyst in an enhanced way.
