Part One

Produce a report that describe for this crime scene, how you would, * Preserve and prevent contamination.
* Search and record the crime scene including listing and storing the evidence. (1500 to 2000 words)

Crime scene 27c Leek Road.

The First Officer Attending (FOA) the scene will have carried out an initial assessment of

the crime scene and following procedure will have called for assistance and dealt with

any emergencies and made a record of his assessment and actions , making note of the

time his arrival time, were any points of entry open or closed, locked or

unlocked, environmental factors and any witnesses and communicate his/her assessment

to the designated Officer in Charge.(OIC)

The FOA will initially be responsible for the preservation of the crime scene and will have

created a cordon, possibly an outer and inner cordon, which a uniformed officer(s) should

patrol and log personnel authorised to enter the crime scene area. Authorised personel

include, the FOA , OIC, uniform police officers, Scenes of Crime Officers, Forensic

Scientists, Pathologist, Police surgeon, Specialist photographer/videographer, Forensic

Entomologists, Forensic anthropologists and bomb disposal experts and in the case of

Arson, a fire investigation specialist.

After handover from the FOA to the OIC, a Common Approach Path (CAP) can be laid

down with the deployment of stepping plates from the cordon to the focal point of the crime

scene. This should be laid in a manner that is unlikely to coincide with the perpetrator(s) or

victims movements in or out of the scene. As the CAP is created, the course it takes

should be photographed using wide and medium range shots and close up shots of the

focal point before any potential evidence can be disturbed. As the CAP is created the

course will be searched for physical evidence and evidence found should be photographed

in situ before removal in accordance with standard procedure.

All authorised personnel entering the crime scene should be attired appropriately in

Personal Protective Equipment including face mask and overshoes to avoid contamination

of the scene and potential evidence.

It is of the utmost importance that the crime scene should be recorded fully by means of

notes, sketch, photography and videography before being processed. These actions

provide a permanent record of the crime scene in the way it was found and an aide

memoire to the investigating officers, provide an account of the steps taken in the

investigation and record delicate evidence before recovery in case it is destroyed in the

recovery process. Photographs should give both a wide overview of the scene and close

ups of any potential evidence or items of interest in situ. A sketch of the scene should be

contemporaneous and show a wider overview of the scene including dimensions, plotting

the position of evidence found before removal and the locations from where and angle of

photographs taken. Sketches can provide a useful overview providing a greater width and

depth of field of view and show the important features without the distraction of

unnecessary detail as within the photographic record (Jackson R, Jackson J 2011 ).

Notes taken at the scene should include who reported the incident, time and date,

location, nature of incident, the events that took place, the roles and locations of the

people concerned and any change that may have occurred to the scene between the

event and the the arrival of the FOA.

Accurate logs must be made of the identities of all people who have been at the scene and

at what times they were there from the time of arrival of the FOA to the completion of

processing the crime scene.
