Forensic Science Unit 23 A
In forensic science, there are 4 procedures that are done in an investigation this is
● The scene of the crime
● Forensic science analysis
● Interpretation of analysis
● Forensics science and the law and criminal justice system
Documentation
In forensic science, there are many steps/precautions that are taken in an
investigation that involve specialists and authorised personnel, documentation
methods, risk assessments and collecting and the preservation of the evidence.
evidence such as theories, photos etc are thoroughly looked at and discussed and
also will be considered by the team that is doing the investigation, this is done so
they can hope to identify significant witnesses, suspects and anything that is linked
to the investigation. They also discuss any areas that need to be developed in areas
where it is weak in the hope to solidify these areas.
In the investigation of forensics, it is very vital that the documentation methods are
used correctly to hold the data throughout the whole investigation process the
consequences of not having a good set of data kept in the documentation could lead
to inadmissible evidence in court and also evidence that has either not been
correctly written down or not noted down could lead to the guilty party getting away
with a potentially serious crime.
There are many important pieces of documentation one of which include the cordon
log this log has data on everyone who has entered the crime scene and also when
they leave the crime scene this is vital as there needs to be a track on who exactly
has entered the crime scene as it shows exactly the reason they have entered the
crime scene. In some cases, the SSU and emergency services such as the
paramedics or firefighters could contaminate the crime scene by helping a victim
who needs medical attention, by having a recorded track of these services on the
cordon log would allow them to rule them out as persons of interest.
Other than the cordon log there is also another documentation method which is
sketches and photographs. This is done by an investigation officer and is one of the
most effective ways to represent a crime. as they provide exact and significant
pieces of evidence and also detail with exact measurements of the site of where the
evidence is at the crime scene.
, A way that forensic scientists record details about their examination is by using
examination forms that store the examination of evidence that is submitted to their
laboratory. If this was not included in the procedure then there would be no record or
data that is a piece of evidence being examined. Other than this there are also
evidence labels. These are used as a documentation method too which makes items'
potential evidence to be easily identified at a later date, these are also significant
because they show when the last person touched the item and also who exactly
touched the item.
Authorised personnel
typically one of the first people to be called to the scene is the cordons these people
carry out specific measurements so that people such as the media or other people
who are not authorised to enter do not contaminate the potential evidence that could
be found, They even take away any traces of evidence that could be found in their
shoes, clothes and other places. In order to restrict access for entry, they use items
such as tape that is used to tape off the scene and also barricade the entry of the
scene. In some cases, they have a police officer to guard the crime scene so no one
enters. Once the cordons have finished with the measurements they use a log sheet
and note down anyone that enters and leaves the crime scene also the time some
examples are police officers, witnesses, paramedics etc. This exact measurement
will limit the people who will need to be examined when evidence such as
fingerprints and footprints are found.
The crime scene sometimes will require the cordons to contact scientific support to
assist in the scene. The SSU uses highly sophisticated and modern technology that
can examine the forensic evidence collected from a crime scene. this includes
personnel that are specialised in efficient crime science examination, lab
examination, DNA etc
Forensic expertise and CSI is one unit of the SSU; these are specialists that will
carry out forensics examinations and this is done in the laboratory. examinations
include items from the suspects and victims of crime such as Blood, saliva and
cellular material. This is done by using equipment and techniques.
The SSU also examines weapons like firearms to look for any DNA of the person
that used or handles the firearm; this is done by the DNA profiling department of the
SSU.
Another unit of the SSU is the major crime unit they will attend crime scenes that are
major examples including murders and sexual offences. They examine carefully for
things such as blood pattern analysis, and luminal and species testing.
