What Is Crime Scene Analysis?

Also referred to as crime scene response, crime scene analysis is a systematic method of evaluating a location where crime was committed. This entails observing for and collecting evidence, which is colloquially known as “bagging and tagging” since the evidence found is placed inside a sealed container and identified as to what it is, where it was found, and when it was found.

In order to accurately narrate and record a crime, investigators and detectives rely on evidence collected and evaluated through crime scene analysis. Such evidence is pertinent in making claims as to what occurred, where it occurred, who was involved, and what other elements are part of it. The process of crime scene analysis is not haphazard; it involves meticulous and methodical work in order to sort through everything within the perimeters of a crime scene and establish what items are relevant to the crime committed.

Before processing evidence, the first step of crime scene analysis is to ensure that the area that is to be processed is secure form any other unnecessary people. This is to help crime scene investigators to process evidence that have not been tampered or compromised. Second step of crime scene analysis is for the special investigators to look over the area and make detailed notes of what they can observe as well as taking photographs of every inch of the area. After notes and photographs, physical evidence is identified and collected. A certain protocol is employed in the collection of evidence to ensure that it is secure and free from any possible contamination.
