Tools of Crime Scene Analysis
Specific approaches are followed by crime scene investigators. The straight gathering of evidence is not the only thing it consists of; interpretation and analysis still exist as well. The size and structure vary tremendously depending on who or what was involved. Therefore, the CSI team and officials are provided with a wide array of “tools of the trade”.
Photographs
The scene will eventually be cleaned, so photography is necessary. If you don’t, you will never again have an opportunity to recreate scenes.
When you take shots at the scene, you should, and must compensate or make accurate the coverage by taking many overlapping shots. This will provide for basis reconstruction of the crime scene area. These 5 things will help you greatly when using a camera a the scene:
*make sure to document all evidence
*verify all witness accounts
*attain additional CSI resource tools
*make a record of the scene
*visually recreate the entire scene
Crime Scene Diagram
One mandatory step is making that initial sketch of the scene. Write this when you do it on clean paper, so as to make sure it is very legible. Consider outer limits of the scene when making the initial sketch. After that, add all the smaller details, such as landscaping, drive positioning, decorations, and other more detailed aspects.
A sketch and drawing is about as important as a photograph, Used to produce a concrete representation of how the scene looked. Proper assessment of a crime scene can then be had. If you can not draw very well, you can still take a photo of the scene, as a more viable format.
Human Models
Measure the victims positioning and everything else relative to body positioning as soon as possible. These details could impact how the evidence is interpreted by others as the investigation comes along. Physical qualities of the suspect can then be guessed, as well, telling you if there have been signs of struggle or not. By doing this now, later on you can compare notes with the medical examiners office on what the possible cause of death may be.
Crime Analysis Software
Software has become a standard convenience in modern times. In the case of CSI, Software, it allows quick analysis of objects and situations that in the past, would have taken investigators much longer.
Following are a few used pieces of software:
• Software for Image Editing – Used to document all photo evidence at a scene
• Modeling and Draft software – Creating 3 dimensional recreations is invaluable at any scene.
• Photogrammetry software – Allows investigators to get the dimensions of evidence correct using the software.
• Presentation software – Produces, for demonstrations and perusal, slides of the evidence for use in court or further analysis.
