Abstract
Crime scene reconstruction is a process in which the action or events, occurred at the scene are determined or eliminated through the analysis of location and position of evidence present at scene. Reconstruction process of the crime scene can help the investigating agencies to conclude the findings to a logical end. Sometimes, the facts at hand seem to be contradictory at the preliminary level, which then, are conformed to the reality in the reconstruction process, which includes the four basic principles i.e. recognition, identification, individualization and reconstruction used in forensic examination of evidence. In this study, one such case of firing, the reconstruction approach was used for deciding the case. The knowledge of linear and angular momentum of physics was used as tool for reconstruction approach in the case under study. Keywords: Impact, Inertia, Recoil Momentum, Point of Intersection, Ricochet, Droplets, Scattering
Introduction
This is a case of death of a constable due to fire arms injuries with his .303 caliber rifle on duty at sentry post of a senior police officer residence. At the sound of firing, his colleagues rushed to the place and found the constable lying down in blood pool on the floor. This was in early in the morning hours of the day. Some good witted fellows captured the scene through their mobile phone camera. After the postmortem examination, the last rites were performed by the family but the problem started as the constable sustained entry wound at the back of neck and the exit at the right eye area , unusually of suicidal incidence. Higher authority decided to register a case under section 302 of IPC. The reconstruction of crime scene approach was used to know how exactly the incident occurred. Finally, the forensic reconstruction process proved this incidence as a case of suicide.
The Problem Addressed to Forensic Unit
Circumstantial evidences suggested that the incidence was of suicidal nature but the position of the body and the entry & the exit wounds prima fascia did not suggest the incident as suicide. After having a case registered, it became technically a problem for investigating team to provide scientific explanation for this incidence. With the study of the photographs taken before removing the body and the reconstruction process at the scene, scientific explanation for the incidence could be provided to investigating officer of the case.
The problem addressed to -
1. Can the position and the posture of the person who sustained fire arms injuries be assessed just at the time of incidence?
2. Where was the fire arm (the rifle) involved in the incidence at the time of firing?
