In an essay format, discuss the important facts that an investigator
who investigated a scene of incident must include in his or her
statement.
Give this one a try later!
= The place or location where the evidence was found
= The case number
= The date and time when the evidence was found
= The names of the persons who have handled the evidence
= An explanation on how the evidence was packaged
= The name of the person who packaged the evidence
= The description of the physical evidence
= The serial numbers of the physical evidence
= The tracking numbers allocated to the physical evidence
= The seal number of the author of the covering letter.
The statement must begin with the date and time when the investigating
officer was tasked with the investigation. All the facts stated thereafter in
the statement must contain the chronological sequence of events during
the investigation and must explain the following:
= where the physical evidence was found;
= what led to its discovery;
= the circumstances under which it was found, and in what manner the
evidence was:
o collected
o packaged
o preserved, and
o dispatched.
To eliminate confusion during the investigation, and especially during the
trial, it is of utmost importance that physical evidence collected by the
investigator is described in the statement. The descriptions must refer to the
numbers allocated to evidence completely and correctly.
, The serial numbers appearing on physical evidence or exhibits, such as the
engine number of vehicles, serial numbers of firearms and radios, must be
documented accurately by the investigator.
(+) The chronological history of the evidence
(+) If changes are made to the evidence they should be disclosed.
(+) If the integrity of evidence has been maintained, physical evidence will
therefore be authentic.
(+) The proof as to who had contact with evidence, what time and under what
circumstances.
(+) Ensuring that there is no room for negligence and careless handling.
(+) Preservation, packaging and transporting.
(+) Correct safekeeping.
(+) Ensuring that the exhibit is not contaminated.
(+) Submission to court with a complete explanation of its itinerary.
(+) Never allow anyone to handle the exhibit.
(+) Once physical evidence leaves the investigator's possession, a detailed note
must be made describing the condition of the physical evidence and the name
of the recipient.
(+) Signatures from persons who receive physical evidence or the exhibit.
(+) Dual responsibility should be recorded if more than one person has custody
over the exhibit.
, = This principle makes provision for non-visible electronic traces.
= In the case of an active cellphone handset, there is non-visible contact
between the handset and the scene of incident but the locational contact is
recorded on the computer system of the cellphone network (which is not the
scene of incident).
= The technological footprints are not only the traces left behind at the scene of
incident as a result of a call being made. They also include the traces left by the
automatic continuous registration of a handset without there having been a call
or text message made, or physical contact between two objects.
= This principle premises that the electronic record is kept at a site away from the
geographical location where a handset was at a particular point in time.
= In the case of a cellphone call, the contact is made between the handset and
the "locational area" (as per GPS coordinates; specific space) of the crime scene
and the invisible signal is momentarily present at the scene.
= The contact is, however, registered (captured) in the memory of the computer
system (which is not the crime scene).

= Documenting the suspected bite-mark injuries.
= Photographing the suspected bite-mark injuries.
= Collecting the DNA samples.
= Documenting any body part suspected of containing trace
evidence material.
= Placing the deceased in a decontaminated body bag.

positive effects on crime scene investigation. List the positive effects.
