FORENSIC SCIENCE DEFINITION
Forensic science is the application of
science to criminal and civil laws.
This course emphasizes the application of science to the
laws that are enforced by police agencies in a criminal
justice system.
Forensic science owes its origins to individuals who
developed the principles and techniques needed to
identify or compare physical evidence.

PROJECT 1, PART 1
Our first project will be a quick one.
•
Each group has been assigned a significant figure in the history and development of
forensic science.
• Each of these people has played a role in developing the principles and/or
techniques needed to identify or compare physical evidence
•
It is your job to identify the role that they played, when they contributed this principle or
technique and to explain why it is a significant contribution to the development of the
science.
•
Your group has 35 minutes to create a 3 minute presentation containing all of the
relevant information on your assigned topic. (you choose how it is presented)
• Be sure to include any necessary images or examples to address your Historical
figure.
• You will hand in a written explanation of your topic, no longer than 1 page(typed),at
the beginning of class on Thursday 2/7.

HISTORY

•
•
•
Mathieu Orfila—the father of forensic toxicology.
Alphonse Bertillion—devised the first scientific system
of personal identification in 1879.
Francis Galton—conducted the first definitive study of
fingerprints and their classification.
Leone Lattes—developed a procedure to determine
blood type from dried bloodstains.
Calvin Goddard—used a comparison microscope to
determine if a particular gun fired a bullet.
Albert Osborn—developed the fundamental principles
of document examination.

HISTORY

Walter McCrone—utilized microscopy and other
analytical methodologies to examine evidence.
Hans Gross—wrote the first treatise describing the
application of scientific principles to the field of
criminal investigation.
Edmond Locard—incorporared Gross’ principles
within a workable crime laboratory.
Locard’s Exchange Principle—states that when a
criminal comes in contact with an object or person,
a cross-transfer of evidence occurs.

USING THE POWERS OF DEDUCTION
What is deductive Reasoning?
Deductive reasoning, deductive logic or logical deduction is the
process of reasoning from one or more general statements
(premises) to reach a logically certain conclusion.
Deductive reasoning links premises with conclusions.
•
If all premises are true, the terms are clear, and the rules of
deductive logic are followed, then the conclusion reached is
necessarily true.
• In deductive reasoning, a conclusion is reached from general
statements
• It is the basis of scientific reasoning!

EXAMPLE OF DEDUCTIVE ARGUMENT
1. All men are mortal.
2. Aristotle is a man.
3. Therefore, Aristotle is mortal.
The first premise states that all objects classified as "men" have the
attribute "mortal".
The second premise states that "Aristotle" is classified as a "man" –
a member of the set "men".
The conclusion then states that "Aristotle" must be "mortal" because
he inherits this attribute from his classification as a "man".

SKILLS OF A FORENSIC SCIENTIST
Must be skilled in applying the principles and
techniques of the physical and natural sciences
to the analysis of the many types of evidence that
may be recovered during a criminal investigation.
May also provide expert court testimony.
• An expert witness is an individual whom the
court determines possesses knowledge relevant
to the trial that is not expected of the average
person.

SKILLS OF A FORENSIC SCIENTIST
• The expert witness is called on to evaluate evidence
based on specialized training and experience that the
court lacks the expertise to do.
• The expert will then express an opinion as to the
significance of the findings.
Forensic scientists also participate in training law
enforcement personnel in the proper recognition,
collection, and preservation of physical evidence.

THE CRIME LAB
The development of crime laboratories in the United
States has been characterized by rapid growth
accompanied by a lack of national and regional
planning and coordination.
At present, approximately 350 public crime laboratories
operate at various levels of government—federal,
state, county, and municipal.

THE CRIME LAB
The ever increasing number of crime laboratories
is partly the result of the following:
 Supreme Court decisions in the 1960s responsible for police placing
greater emphasis on scientifically evaluated evidence.
 Crime laboratories inundated with drug specimens due to
accelerated drug abuse.
 The advent of DNA profiling.

SPECIAL FORENSIC SCIENCE SERVICES
After a human body expires there are several stages
of death.
 Rigor mortis results in the shortening of muscle tissue
and the stiffening of body parts in the position at death
(occurs within the first 24 hours and disappears within
36 hours).
 Livor mortis results in the settling of blood in areas of the
body closest to the ground (begins immediately on death
and continues up to 12 hours).
 Algor mortis results in the loss of heat by a body (a
general rule, beginning about an hour after death, the
body loses heat by 1 to 1-1/2 degrees Fahrenheit per
hour until the body reaches the environmental
temperature).

EVIDENCE ;THE FRYE STANDARD
The Frye v. United States decision set guidelines

evidence into the courtroom.
To meet the Frye standard, the evidence in
question must be “generally accepted” by the
scientific community.

FRYE NOT ABSOLUTE
However, in the 1993 case of Daubert v. Merrell Dow
Pharmaceutical, Inc., the U.S. Supreme Court
asserted that the Frye standard is not an absolute
prerequisite to the admissibility of scientific evidence.
Trial judges were said to be ultimately responsible as
“gatekeepers” for the admissibility and validity of
scientific evidence presented in their courts, as well
as all expert testimony.

THE DAUBERT CRITERIA
In Daubert, the Supreme Court offered some guidelines as
to how a judge can gauge scientific evidence:
1) Whether the scientific technique or theory can be (and
has been) tested.
2) Whether the technique or theory has been subject to
peer review and publication.
3) The technique’s potential rate of error.

Identify 4 clues at each scene
•
Send the evidence to the lab
•
Speak to the lab professionals and answer a question
• You will get 1 chance to answer it correctly
