Forensic Science is the application of science to
law.
“Forensic science is the application of science to
those criminal and civil laws that are enforced
by police agencies in a criminal justice system”
Also called criminalistic


Whenever 2 objects come in contact
with one another, they exchange
some material
Locard strongly believed that every
criminal can be connected to a crime
by dust particles carried from the
scene

This material that is transferred is called Trace
Evidence



The Scene is simply defined as the actual site or
location in which the incident took place.

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)


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)




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

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

Because you are writing in complete sentences you do not
need to write the question

2. What may happen if the first officer on the scene forgot to secure
the scene?
3. Why are photos and sketches an important part of crime scene?
