Slide 13
The Scene is simply defined as the actual site or location in
which the incident took place.
Slide 14
It is imperative that the first responding officer on the scene
protect the individuals involved as a first priority. Protecting
the evidence is the second task. The entire investigation could be
dependent on this. Why is it important to secure the scene? Scene
is secured by a restricting a perimeter, utilizing rope or tape.
Entry of authorized personal is recorded. All unauthorized personal
or removed to eliminate possibility of contamination or transfer of
evidence (Locard)
Slide 15
Witnesses must not be allowed to talk with each other. This is
done so they do not compare stories and so that a new story is not
created. (collusion)
Slide 16
A forensic examiner needs to be able to scan the scene to
determine if there is a primary crime scene or potentially a
secondary crime scene. Primary scene- place the incident occurred
Secondary scene- any other place connected to the incident Ex. This
is done by the team leader who assumes control and assigns other
duties such as who will be the : Photographer Log Recorder Sketch
Artist Evidence Recorder and other personnel Specialist-
entomologist, blood splatter, etc
Slide 17
Done by the photographer A photograph is a two-dimensional
reproduction of the crime scene. It serves as the permanent record
of the crime scene. Everyone involved in the investigation will
have an opportunity to look at theses photographs (the District
Attorney, the defense counsel, homicide detectives, etc). They are
also very important to you because the photographs will serve as
memory joggers when you have to get up on the witness stand and
testify. Good pictures are essential because most trials do not
take place until a year or more has passed. Videos can also be
taking at the crime
Slide 18
This is done by the photographer Requirements of each photo:
Photograph overall area from up close and medium range and far away
prior to moving anything. Close up of each piece of evidence with
evidence marker (including corpse) Include a point of reference to
indicate size. ( a ruler, a pen, a car key)
Slide 19
