Overview
Crime scene investigation is the systematic process of documenting a location associated with a crime and recognizing, collecting, and preserving physical evidence so that it can be analyzed and used to reconstruct events and support legal proceedings. It involves securing and examining the scene, recording it through photographs, sketches, and notes, and gathering evidence such as biological traces, fingerprints, fibers, firearms residue, and other materials while maintaining a documented chain of custody to ensure integrity. The work draws on multiple forensic disciplines, including biology and DNA analysis, chemistry, fingerprint examination, ballistics, and pathology, to link evidence to people, objects, and sequences of events. Careful and methodical investigation at the scene is essential because evidence is fragile and can be easily lost, contaminated, or altered, and because the conclusions drawn later in the laboratory depend on the quality of what is recovered. Within the broader field of forensic science, crime scene investigation forms the critical first stage that connects an event to the scientific analysis and interpretation that follow. This page presents encyclopedic background on crime scene investigation, its methods of evidence recognition and preservation, and its role within the forensic sciences.
