Without any doubt, the job of a crime scene investigator does not belong to the exotic or romantic types of job due to the fact that this job requires deep evaluation, examination, and complex analysis of the crime scene investigations. According to the definition, a crime scene investigator should provide identification and information acquisitions of crime evidence that are pivotal parts of the law enforcement process.
Indisputably, the main role of the crime scene investigator can be particularly characterized through forensic investigation (including evidence obtained by corresponding packaging and documentation), performing a fingerprint search of the scene, the recording of a scene, and photography. It is generally true that the crime scene investigator is required to attend different kind of scenes which can include the testing of stolen bags or jewellery at the dwelling houses to more significant crimes, such as armed robberies, sexual assaults, and murder. Moreover, the UK Higher Physical Education Sciences Academy Center (nd) indicates that the crime scene investigator is amenable to gathering, labelling and delivering crime evidence, documenting autopsies, writing crime reports, scrutinizing, and testifying criminal incidents in court as experts. Undoubtedly, crime scene investigators are required to perform arduous duty and be ready to take appropriate measure at any time. The stark reality indicates that, despite a 40-hour work schedule, the crime scene investigator is required to work after shifts and be available 24 hours in case of emergency. Furthermore, the crime scene investigator should have a good command of anatomy, chemistry, forensics training, and general sciences. Additionally, the crime scene investigator should hold a bachelor degree that assures his/ her level of received education and knowledge (Scott 2012).
The basic responsibilities of the crime scene investigator are to compare and classify fingerprints received according to files, to uncover the prime motive of the crime, to reconstruct the crime incidents, to determine the sequence of events that has a big influence on the incident, and to recover all details of the crime. Furthermore, the crime scene investigator should provide an effective examination and a thorough analysis of the crime events. In this case, he/ she should assiduously investigate the indoor and outdoor factors that led to the crime including minor details. Moreover, one of the basic responsibilities of the crime scene investigator is the formal documentation of the crime. This documentation includes diagrams, photography of the scenes, sketches, and written records. Additionally, the crime scene investigator should properly collect crime evidence including articles of clothing, clipping, hair, and fibber samples, questioning of the witnesses, and marking spots where evidence was gathered. Moreover, the crime scene investigator should participate in the various meeting with lawyers and other legal officials who prepare criminal proceedings. During these meeting, the crime scene investigators usually explain the evidence means. Finally, the crime scene investigator is required to testify in court by providing personal conclusion of the crime examination (Ray 2012).
All in all, the crime scene investigators should be capable of making a deep analysis of the crime scene. Their works strictly adhere to the disclosure of main evidence at the crime scene by applying modern means of technology. In addition, the crime scene investigator should have expert knowledge in law, communication skills, a strong physical frame that are important in the ascertaining of crime evidence and making conclusion regarding obtained details of the crime scene examination.
