Personnel involved. - ANSWER>Police officers/ detectives who investigate the crime.
*Forensic specialists with expertise in different areas.
*Crime scene investigators - in the UK scenes of crime officers (SOCO's) who collect evidence.
*The Crown Prosecution Service (CPS) which decides if a suspect is charged.
*There are also other agencies e.g. the National Crime Agency which is responsible for leading
the UK's fight to cut serious and organised crime, and HM revenue and customs.
*Forensic scientists who interpret the evidence.
*A pathologist who determines the cause and means of death, which can provide vital
investigative evidence.
Scene's of crime officers (SOCOs) - ANSWER>These roles are often depicted on television as CSIs
all crime scene investigators and are employed by the police service to preserve and protect a
crime scene and recover evidence.
*Clearly, such evidence can be vital in criminal investigations. - Ian Huntley.
*It is essential the evidence at a crime scene remains uncontaminated and is collected as soon as
possible to provide reliable evidence in a criminal investigation.
*SOCOs Typically search for trace evidence such as gunshot residue, fingerprints and hairs and
fibres, Should contamination occur, the evidence will be inadmissible (unable to be used) in
court, However, such risk is minimised as SOCOs are trained and qualified in this area.
*They usually operate an on-call system and are therefore always available to assist in criminal
investigations.
Limitations of SOCOs - ANSWER>>There are many times when the role produces limitations to
solving a crime:
*SOCOs may be exposed to hazardous substances in the course of their role, such as
contaminants contacting the skin or airborne substances that could enter the mouth. Why is this
a limitation?

this.
*Such risks are minimised by the wearing of protective clothing, including masks and glasses.

attention to detail. Failure to collect evidence correctly can lead to a guilty person going free.

*The SOCOs left the bra covered in Meredith's blood at the crime scene.
Forensic scientist - ANSWER>Forensic scientists review evidence from a crime scene and produce
information for court.
*Evidence such as blood and other body Fluids are analysed in a laboratory and interpreted.
*This information can assist a court in making a decision on producing a just result.
*They can narrow down suspects, find more evidence, produce a timeline of events - they have
expertise knowledge.
One of the advantages of forensics is that it includes many specialist areas with expertise such
as:
· Computers. - white collar/technological crime - computer use/history.
· Toxicology (drugs) - were victims under the influence? / could drugs have caused the death?
· Dentistry.
· Fire. - how it started/burn time.
· Psychology.
