Chapter 7 - Crime Scene Investigation

Abstract

This chapter explains the basic concepts of crime scene investigation such as the nature of crime scene investigation, its role in the process of criminal investigation, and its importance to the reconstruction effort. Crime scene investigation refers to the process of establishing the scientific facts of a case using the physical evidence that is produced in relation to suspected criminal activity. The goal of crime scene investigation is to provide for scientific crime reconstruction and crime scene analysis efforts. The results may be used to answer investigative and legal questions. Each case has its own such issues that cannot be predicted; this demands a thorough effort at the outset to allow for the most complete retrospective inquiry of crime scene evidence. Crime scene investigation occurs not only within the confines of yellow barrier tape under the watchful eye of law enforcement officers and investigators, but also it is a broad inquiry that seeks to establish the record of physical evidence during an event or a series of related events. It is ultimately the unified result of aggregated crime scene examination and processing efforts; forensic laboratory examinations and analyses; medicolegal examinations and analyses; and collateral victim–suspect evidence and history.
