Identifying evidence in a systematic crime scene examination is the
hallmark of a highly competent forensic examiner.
Scenes-of-crime officer (SOCO) trainees are taught these
skills in order to prepare them for their future career
in the New South Wales Police Force. The ability to
assess and examine a crime scene or incident through the
gathering of all available information from various
sources is extremely important.
Those officers who undertake the job of being a
scenes-of-crime officer are trained at the Goulburn
Police College for a period of time, and also trained in
the field as well. All personal are trained in certain
modules, which include finger print gathering, and
associated photography, also crime scene and general
photography, crime scene examination and evidence
preparation, plus court presentation. They also attend
lectures in associated support disciplines by other
government departments and private industry. During the
course every officer performs work at his/her station
providing the opportunity to put into practice their
crime scene studies.
Trainees are also taught about DNA. This requires
working with pathologists and biologists on post-mortem
examinations. This prepares trainees for a very
important part of crime scene work, being involved in
cause of death investigations and gathering of forensic
samples, including DNA samples from scenes for
identification purposes.
Fire
scenes and explosion examination skills are other
important areas of study and include the ability to
recognise suspicious fires so that the expert fire scene
examiners of the New South Wales Scientific Unit can be
called to further investigate the scene.
Further
crime scene examination skills learnt include recording
and collection techniques, ballistics and tool marks
study, vehicle identification, blood splash examination,
shoe and tyre impressions and examinations and
recording, analytical support services and document
examination considerations.
About
60 per cent of a SOCO's workload involves making
fingerprint examinations at crime scenes. Trainees are
therefore instructed in the various examination
techniques and processes involved in developing latent
and other fingerprints.
They
study the composition of the fluids that make up latent
and visible fingerprints, fingerprint patterns and
various characteristics of fingerprints and the surfaces
on which they may be found. As in all police work the
documentation of the examination and the following of
the correct chain of evidence are integral elements in
the training of SCOC's. Study and training also is
undertaken in the fingerprinting of unidentified
deceased people to aid identification.
Photography
and video recording knowledge and skills are part of the
SCOC training. The subjects covered include the use of
police still cameras and video equipment, practical
photographic and video exercises in colour and black and
white photography and other specialist photography.
A study of the characteristics of light, images and
illumination are important areas of the photographic
science, as light and its characteristics, and its
ability to convey recordable images, are integral to the
study of photography and its use in police forensic
work.
To
complete the SOCO course officers are assessed on crime scene
examination skills and knowledge, the preparation of
evidence for court. Those officers who successfully
complete the course are than transferred to a
scenes-of-crime unit to undertake on-the-job training
and assessment. They are also required to undertake a
major research assignment and successfully complete it
within a required period of time. Once this has been
completed they are assessed as to whether or not they
are classed as a competent crime scene examiner or not.
The
workload of a SOCO is often high and it is important for
the officers to have suitable temperament and
disposition to deal with, at times, abhorrent and
distasteful scenes and investigations.
It is also important for officers to continue their
police studies and specialist training in order to keep
abreast of new methods and continued knowledge and
skills development for them to progress to the higher
positions in the specialist field and other policing
areas.
