Processes Involved In Crime Scene Investigations

What is the process of doing a crime scene investigation? In this article, we will be discussing the basics of crime scene investigation and what are the typical scenarios along with the process.

The first step is to through the crime scene. The main reason for checking the scene is to gather evidence.

Next step is to have the things analyzed. For material things, forensic experts do the job. However, for 3-In-1 Forensic Video Analysis Software and voice recordings, there is a specialized division who analyzes the data. Normally, for analyzing voice recordings, they are using the sound wave measurements, mix and match the audio, and they will find a lead.


For video recordings, normally they are spotting the familiar places, the familiar faces, and the things that might lead them to find the lead. For fingerprints, it is easy to determine who has the last touch since the information is stored in the database. They use the best photogrammetric tool-set for measuring any subject or crime scene captured in at least one or several images/video frames.

When studying trace evidence found at a crime scene, forensic scientists use in their arsenal tools at their disposal besides microscope. Using the following method, which is the most commonly used, forensic scientists can ascertain the chemical characteristics of trace evidence.

Infrared (IR) spectrophotometry: This laboratory method requires exposing samples of trace evidence infrared radiation. different sample absorb infrared light at different wavelengths. It is these differences that distinguish one from the other samples.

Neutron Activation Analysis: This method is a little complicated and requires the use of nuclear reactors. Neutron shot in the sample and collide with components. The result is that each component of the release of radiation at a unique energy level. By measuring the level of their radiation emissions, forensic scientists can reveal the chemical characteristics of the sample. This procedure is very useful in studying the paint, hair, metal, soil, and many other samples.
