Theoretical and Practical Security Aspects of Crime Scene Investigations and Evaluation of Evidence

Summary/Abstract: Detecting and locating physical evidence during crime scene investigation requires special expertise and experience which should contribute to proper assessment, access, organization and coordination of the investigative activities. Securing the scene of the investigation is very important and, perhaps, it is one of the key activities on which all further processes depend. As a logical and intellectual act, the inspection, above all, represents a mental reconstruction of the dynamics of the criminal act that happened, with two objectives: the first objective refers to being able to understand the chronology of the activities i.e. the analysis of the logical layout of the physical evidence; and the second one, consequently to the first, refers to predicting the places where the latent physical changes could have happened. Trace evidence which is detected during the crime scene should represent logical consequence of a criminal act i.e. they should be in causal relation with the actions undertaken by the perpetrator or perpetrators. For these reasons recovering evidence does not mean simply collecting and packing it up, but implementation of appropriate strategy as a starting point for investigating the crime scene, which presents an organized, methodical, systematic and logical process.
