UNIT 23: FORENSIC EVIDENCE, COLLECTION AND ANALYSIS
LEARNING AIM A: UNDERSTAND HOW TO GATHER FORENSIC EVIDENCE, THE INTEGRITY TO FORENSIC
INVESTIGATION AND THE IMPORTANCE OF HEALTH AND SAFETY
Forensic science plays an important part of the criminal justice system. It is an essential tool used for criminal
investigations, used to analyse, and examine evidence and findings which can help assist in cases and prosecutions of
suspects in court.
This assignment will outline the roles of authorised personnel’s and crime scene procedures that are carried out, to
have trustworthiness evidence that is reliable, accurate and crucial to the investigation, when shown in court to
make conclusions.

A.P2 OUTLINE THE ROLES OF CRIME SCENE AND AUTHORISED PERSONNEL WHO ATTEND CRIME SCENES.
ROLES OF THE SCIENTIFIC SUPPORT TEAM
FIRST ATTENDING OFFICER (FAO):
When a crime is reported, a FAO will arrive at the scene wearing full Personal Protective Equipment (PPE) at all time to
prevent any contaminations and to protect themselves from hazardous substances such as (bodily fluids), and will then
carry out an initial assessment, as well as this they would carry out several other duties such as restricting and securing
the crime scene using tape to prevent access to unauthorised personals such as the public, and will protect the evidence
from the weather and other uncontrollable conditions, call emergency services on the scene, calling first aid or
paramedics to preserve a life or treat injured suspects or witnesses and will also record of any alterations made during
first aid such as movement of victim or object. They will also take notes and interviews from suspects and witness of the
incident occurred and will detain and arrest suspects if necessary. When authorised personnel arrive any relevant
information will be shared. (Anon, n.d.) [3]
SCENE OF CRIME OFFICER (SOCO):
A SOCO works with law enforcement officers such as the police to help solve cases. They attend many types of crime
scenes such as murders, rape, robbery, and in some cases post-mortems. (targetjobs, n.d.) [5] SOCO make a common
approach path of a crime such as finding the entries and exists and an effective pattern to look at the scene so that they
can observe and investigate in detail every bit so that nothing is missed out and to conclude what could have potentially
happened in what way, by matching the pathways. They photograph and collect evidence and make a detailed sketch of
the scene in case anything is moved and tampered with. They also take notes of what they have seen regarding the
crime scene and will pass it to a person higher up when needed and to keep as safe evidence if need in court. Once
evidence is collected by a SOCO will appropriately package the evidence separately and will label it with name, date,
item name, and yellow stands with numbers. This will be recorded on to a continuity and chain of evidence.
FORENSIC COMPANY:
A forensic examiner is to collect items which are evidence to the crime and can help in the case anyway, from the crime
scene wearing full PPE and making sure that the evidence is not contaminated with another item and is collected and
put into separate bags. Forensics scientists must not be biased when analysing and finding evidence. The company itself
will receive the items and will then log them into a system call LIMS System (Chain of Custody) and will create a casefile
where all evidence is kept for safeguarding until the case is solved. The Forensic reporters will show up in court to show
their findings from the evidence, this will help bring about an outcome of the case and a conclusion will be made, by the
jury.
EMERGENCY SERVICES:
When arriving at the scene, all emergency responders are told to assess the health and safety hazards before entering
the scene, to restrict and protect access to the scene. They are also told to wear appropriate PPE (e.g., body suit, gloves,
masks, googles) to protect the body from hazardous substances (e.g., blood, body fluids). To request any resources and
equipment that is in need for help, also to determine the number of bodies on the scene. As well as this all services,
must approach the scene as a potential scene of crime to take appropriate measures and to act according so that the
scene is preserved, and a potential life can be preserved and saved by paramedics and to stop any fire if there is from
spreading by firefighter. Any movement that has occurred during the crime scene must be reported and documented so
that all evidence that is shown to court is reliable, and to do so without disturbing an area of a scene. A body camera is
worn in case this occurs which can help with the investigation if there is any implications in the evidence. (Hartle, EMT-P
and AS, 2020) [4]
CRIME SCENE MANAGERS:
The crime scene manager is the lead of the investigation. Its responsibility and role is to lead a team of investigators, any
authorised personnel present at the scene such as forensic scientists, officers. It manages what enters and leaves the
crime scene and who is allowed to enter it. All authorised personnel will report to the crime scene manger, they will give
instructions which must be followed. After everything is done, the crime scene managers will carry out a final
walkthrough alongside the SOCO, ensuring that everything has be executed accordingly. At the end they would have a
brief session with authorised personnel on the crime scene talking about what went wrong and what actions are to be
