Key Role In Crime Scene Investigations

The goal of any crime scene investigation is to assist in demonstrating what occurred and to determine who is guilty of committing the crime. So, it is very crucial that each crime scene investigator follows the correct procedures and carries out the investigative responsibilities. There are many critical parts of an investigation. Each and every crime scene that an investigator comes across has to be properly secured, recorded and searched.
Firstly, securing the crime scene is a crucial responsibility of the initial responding officers. The preeminent significance of securing the crime scene can be better understood by evaluating Locard’s principle of exchange, which suggests that when objects come in contact with one another, there is always …show more content…

These recordings will play a key role in the trial process (Warrington, …show more content…

In my opinion, a crime scene would not exist if it was not secured because secured boundaries are what informs us there is a crime scene. If the crime scene was not secured then any chances of finding usable evidence is greatly diminished because the evidence could be contaminated. Furthermore, securing, recording, and searching the crime scene is the most critical step because this is the step that is all about preserving and protecting the area. If a crime scene was not protected, evidence could very well be altered. (Warrington, 2011). I feel securing, recording, and searching the crime scene is the most critical out of the three. In my opinion, if an investigator did not secure, record, or search a crime scene than the other two concepts would not be needed. If a crime scene is not secure then the evidence could disappear or be contaminated. If the evidence
