CRIME SCENE

CRIME SCENE 1
Crime scene
A crime scene is a specific place in which a certain harmful dangerous activity
occurred. Crime scene investigators usually need to have adequate knowledge in handling
crime scenes to facilitate the safety of people living within and visiting such an area.
Evaluation of a crime scene begins with total seclusion of the area to allow for a smooth
search and hence possible identification of crime culprits. There are standard procedures for
handling any given crime scene. Evidence collected from a crime scene is important and
require adequate preservation and storage. Likewise, the methods for recording a crime scene
usually include photography, taking notes, and film photography.
Procedures Associated with Crime Scene Evaluation
The process of evaluating a crime scene entails all activities that aim at identifying the
actual perpetrators of crimes (Frade, 2017). The evaluation of a crime scene attracts various
strategies and procedures across law enforcement agencies. Investigators usually have to draft
the most effective procedures across to undertake the evaluations of any given scene of a
crime. The first step in the procedure is securing the place of the crime (Frade, 2017). In
particular, this entails provision of barricades to prevent unauthorized individuals from
accessing the area. The next important step is to draw boundaries around the scene of the
crime as well as around all substantive evidence of a crime at the particular place. The third
procedure is to identify the possible route of the suspect and create a walk through from the
same. This is another important stage because it provides a guideline of the possible activities
carried out by the suspects at the actual place of a crime. The last procedure will be to record
the findings using flowcharts, sketches, and photographs.

PRESERVATION AND COLLECTION OF PHYSICAL EVIDENCE PROCEDURE
Physical evidence in a crime scene include fingerprints, weapons used, blood spatter,
hairs, and any object touched by the suspect at the scene of a crime (Frade, 2017). This kind
of evidence is one of the most crucial components of any criminal offence. Investigators need
to provide adequate storage and preservation of such evidence involves all strategies in place
to maintain pieces of evidence in good shape and condition. Preservation of evidence
involves strategies such as storing objects in locked devices, protecting sketches and keeping
photographs in secured safes.
Collection of evidence begins from the area of an actual crime and involves
investigation of every object surrounding. In particular, this involves locating any markings
of tools at the point of entry in6to a crime scene. This is particularly important in identifying
the kind of tools used in perpetrating a crime (Frade, 2017). Investigating officers also
concentrate on the fingerprints by analysing objects touched by the culprits. By so doing, a
connection develops between scenes of crime and the possible crime perpetrators.
An investigator should record the exact location of evidence or any other object of
evidentiary value with a clear marking. The recording should be in terms of notes, sketches,
and photographs (Frade, 2017). These are the common means of recording evidence of crime
across the globe. Investigators need to have effective markings and evidence of the exact
location of any object that proves to be significant in providing the necessary evidence.
Photographs should be clear and should always have a backup of sketches whenever
necessary. Likewise, the investigators should mark the location of an evidentiary object with
an evidence marker.
