Basics of Crime Scene Investigating

crime sceneWe all have our fantasy to become a part of the CSI in one way, or another. It is nothing but fascinating to see how these people who seem so normal could put together all the clues and figure out the crime. Through their rigid investigation and thorough collection of evidences on the crime scene, it is possible for these CSI members to track down and convict the suspect. But do we really understand how they were able to connect all the clues? Do we really believe that, in real life, it is really as easy how CSI New York or CSI Miami bust a crime? Are CSI jobs that easy?

Let us try to break down the basic processes on a crime scene investigation, just so we will have an idea of how it is done in real life. These shows are just a portrayal of what really is happening, but what these shows fail to show was that it is not only solving a problem through the use of logic. Here’s a quick glimpse behind the investigation of crime scenes.

The first stage of everything is when the investigator secures the place. Usually, it is taped down, and people are asked to leave the scene immediately, so as to not interfere with the possible data and evidences present at the area.

Nothing is touched – from the arrangement of the chairs to the simplest details; everything must stay in its true form. When the investigator tries to formulate theories of what happened, they always take note of everything to create their speculations and predictions. Usually, investigators do a quick check of the place and secure if anything has been moved or altered.

Their next step is documenting the scene with photos, videos, and sketches. All angles have to be documented to analyse every element properly. Nothing is still being touched up until this process.

After the documentation, that would be the only time that the investigator touches, collects and documents specimen that are relevant to the crime. Pieces of hair, blood samples, and any other possible item that could be subjected to DNA treating are taken into consideration. They log and pack all available evidences needed to figure out the crime. Everything must be covered to its minute details when investigating these things. Usually, a crime scene is left as it is for a couple of days, or until the investigation finishes. Sample collection may take days or weeks, depending on the crime that has taken place.

When all is collected and documented, the investigator then leaves the scene and proceeds to logical brainstorming sessions. Usually, the crime scene is cleaned by professional services, and is no longer part of the police’s concern.

Brainstorming sessions usually takes a long time, considering the intensity and the planning of the staged crime. Unlike in television, they do not only study the case for a few days, but instead, they study them for weeks and months, trying to check all possibilities and not to leave out anything.

CSI shows might be cool, but always remember that these things take time and patience. So if you are thinking of having a job in this field, make sure that you take into consideration the stress and time that it will take you to manage and successfully figure out the crime.

Can you quote by phone? What are you capable of doing and when? How much time is needed? Can you return the scene to its original condition? Can you remove the smell? Do you remove biological waste or bio hazardous waste? What hours do you work? How many cleaning products are used? Are you covered with an insurance policy?

The crime scene cleaners will also ask if the water and electricity to work at the scene of the crime. Your cleaner will ask about payment methods and when. Your cleaners can even ask about what hours they can work.

By the time their jobs are completed, expect all biohazard waste, bio waste and solid waste associated to the crime scene are removed. Also, the smell is reduced or eliminated. You cannot expect complete removal of the odor in one day, especially if the dead body was “down” for two or more days.
