Evidences in Crime Scene

Abstract

Crime scene refers to any physical place where an offence has been committed and that may provide potential evidence to an investigating officer. It generally includes a building, vehicles, body of a person and objects found at those places or places in the open air. “Crime scene examination” refers to an examination where scientific or forensic techniques are used to preserve and gather physical evidence of a crime. The study and evaluation of scene patterns, as well as the examination of physical evidence, can be used to reconstruct crime scenes. A fundamental principle of forensics is that every contact leaves a trace. This may be contact of a person with a person, contact of a person with a vehicle or location, or of a vehicle with a location etc. Forensic investigators identify those traces and analyze them to explain what has happened. Some crime scene investigation techniques are complicated and resource demanding, and may not be available to all investigators. It is important to note that even very simple actions—such as taking photographs of victims and scenes or making drawings and plans of premises—can significantly improve the chances of successful, fair prosecution. Blood spatter interpretation, shooting reconstruction, accident reconstruction, and sexual assault reconstruction are some examples of different types of reconstructions. Data gathering, hypothesis generation, examination/ testing and analysis, evaluation of the significance of the evidence, and theory formulation are the five processes in crime scene reconstruction
