Forensic investigation uses science to examine
evidence and solve crimes. Members of the
forensic team use different scientific disciplines
to develop different kinds of evidence to
present in court. Determining who committed
a crime is a team effort between investigators
and scientists. Together, they work to reveal
the whole story of the crime, who committed
it, how they did it, when, where, and why
the crime was committed.
Pathologist
Pathology is a branch of
medicine that determines the nature and course
of a disease by analyzing body tissues and
fluids. Anatomic pathologists perform autopsies
and analyze tissue material taken from patients.
Clinical pathologists diagnose disease by
measure chemicals and cells in blood, bone
marrow, urine, and other bodily materials.
The medical examiner is
usually the first forensic specialist to investigate
a crime. The ME decides on the need for an
autopsy, and investigates all deaths from
violence, accidents, suicides, or suspicious
circumstances. The medical examiner is a pathologist.
Pharmacologist
Pharmacology is a branch
of science that studies the interaction of
chemical substances and living tissues.
The pharmacologist studies
how chemicals are absorbed by the body, how
they affect the body, where they act within
the body, and how they are metabolized and
excreted.
Toxicologist
Toxicology is the science
of poisons, how they act on the living body,
and how they are detected postmortem.
The toxicologist often works
with the pharmacologist to find and examine
poisonous substances or drugs in bodily fluids
and tissues. The toxicologist is also a chemist,
and the two disciplines often work together
on the Forensics Team as the Chemistry/Toxicology
Unit or Chem/Tox.
Serologist
Serology is the study of
bodily fluids in humans and animals.
In the 1970's, identified
elements in blood and body secretions that
allowed them to match a sample found at a
crime scene to a small number of people. Later,
scientists developed a way to extract DNA
from human cells and link it to a specific
person.
Psychiatrist/Psychologist
A Forensic Psychiatrist
or Psychologist compiles information about
a case into a description of a possible suspect.
This psychological profile,
or offender profile, predicts the suspect's
race, religion, ethnic background, family,
education, and motivation for committing the
crime.
