All About Crime Scene Investigation

What is Crime Scene Investigation?

Crime scene investigation jobs have been popularized by several hit crime shows on TV.

Hence, many desires to perform these jobs.

But the truth is, solving crimes and crime scene investigation as a whole is a very complicated job that requires both theory and practical application.

As the name implies, crime scene investigation requires you to:

  • Observe,
  • gather evidence,
  • and analyze any information you can get at the crime scene.

You will then use those data to hypothesize what took place on the crime scene, what caused the death of a victim, what method of attack is used, and the like.

Presence of evidence that would help point to the identity of the suspect must also be gathered.

Although this process appears to be quite simple, it is such a complex job that even learned crime scene investigators require years of working experience before they are able to develop skills needed to become better at this job.

There are multiple ways in which you can study, examine, and analyze evidential items that can help boost your crime analysis.

However, all of these methods are grounded at a few basic protocol followed when processing a crime.

How to Process A Crime?

1- Scene Processing

This is the initial and most crucial aspect of crime scene investigation.

Several methods and skills are involved in this step of your crime scene investigation.

Processing the scene of the crime involves:

  • The interview process with eyewitness for potential information needed in solving the crime,
  • taking photographic evidence of the crime scene and the victim’s body in relation to the crime scene,
  • more intense evidence search,
  • sketching the crime scene,
  • and a few other photographic evidence that could help solve the crime puzzle.

This is the step that determines the success of your succeeding criminal investigation efforts because it involves the collection and documentation of evidence for future reference.

One other factor that makes the scene processing a vital aspect of crime scene investigation is that you cannot re-create a crime scene once you have failed to gather all the information you need for further crime analysis.

2- Evidence Knowledge and Interpretation of Evidence

What will you do with the evidence if you lack the knowledge to interpret and analyze them?

Proper methods of analyzing and handling evidences is crucial in an effective crime scene investigation.

Therefore, it is a strong suit that will help keep the crime investigation going.

Other evidence need to be further studied at criminal laboratories either to see:

  • If there are any fingerprints,
  • or to see samples of blood or other substances.

There have been several instances in the past wherein the DNA of the criminal is found on the evidences gathered at the crime scene that led to their arrest.

3- Criminal Case Processing

The ability to scan crime scenes for evidence, interpreting and analyzing them to find conclusion for a given crime is not a job suited for everyone.

It requires specialized skills and knowledge, especially in terms of the technical aspects of the job such as analysis of:

  • Blood samples,
  • fingerprints,
  • blood patterns,
  • and other tricky part of the investigation.

Once evidence have been examined, you will then put this side by side with any testimony you have gathered from witnesses.

The objective is to have a mental recreation of the events during a crime.

During the recreation, investigators can factor in some possible angles of motivation for the crime that would help trace the suspect.
