In simplest terms, Forensic Toxicology
looks at everything pertaining to any
toxins or poisons that may have legal
significance.

Three main areas: Postmortem Drug
Testing, Workplace Drug Testing, &
Investigation of Contraband Materials.
Toxicologists use blood, urine, gastric
contents, bile & liver, & hair as specimens
for testing.

Pretty much any bodily fluids can be used
in order to determine whether justice is
being served or not.

Think Catch Me If You Can
Forensic Computer Science &
Digital Evidence Examination
Danny Ellison
• What a forensic computer scientist does is
recover evidence used for a crime that has
been erased or deleted from the suspects
computer.
• That information is stored somewhere when it
is deleted it just isn’t erased permanently.
• It is stored in the archives of the computer
and this forensic department deals with this.
Education
• Start with attending the Federal Law
Enforcement Training Center (FLETC).
• Train and gain the valuable skills in order to
pass the certification program for The
International Association of Computer
Investigation Specialists (IACIS).
• This association is by far the largest association
for computer investigation specialists and the one
the government uses to gather the individuals to
collect the digital evidence and then analyze the
information collected.
Evidence from a crime





A typical scenario would play out something like this
example:
A man who is writing love emails to a woman who in
turn he is having an affair with.
His wife finds out about the emails and confronts the
man with the evidence.
The man so embarrassed about getting caught decides
to write the woman he is having an affair with that he
plans on killing her by making it look like a suicide. He
does this by cutting the brake lines on her car so she
can’t stop and dies.
The man not wanting to be a suspect deletes all of his
emails and tells the woman to stop writing for awhile.
While he has deleted the email a forensic computer
scientist can recover these emails and then prove the
motive and the case.
Forensic Engineering
Meghann Carreiro
Forensic Engineering


A quick description of the career:
A Forensic Engineer is responsible for answering the following
three questions:
1. What happened?
2. Why did it happen?
3. How could it have been prevented?



They ultimately reconstruct the crime scene like a puzzle
applying engineering principles.
After an accident, a Forensic Engineer would examine all broken
parts and construct a list of probable failure mechanisms to be
investigated. They will also conduct interviews to determine a
sequence of events.
Following this, their drawings, specifications, and operational
procedures are reviewed and then the final step is to use
analytical and testing tools to confirm their findings.
Education Needed:



A Forensic Engineer must have mastered the basic
technical skills of engineering in addition to being
very knowledgeable in the codes and industry
standards relating to construction, manufacturing and
selling products.
Along with the Engineering degree, they also usually
specialize in electrical engineering, mechanical
engineering, civil engineering, materials engineering
and traffic engineering.
An ideal Forensic Engineer candidate will have:




A good honors degree in a scientific or engineering discipline
Post-graduate experience in a technical role involving on-site
experience
A willingness to relocate
The ability to communicate clearly both orally and in writing
Meghann Carreiro
Example




After a automobile accident a Forensic Engineer
would examine all broken parts of the cars involved
and also examine all available evidence, including
eyewitness accounts.
Then, they will try to piece together a sequence of
events and generate a time line leading to the
accident.
Should they need to defend their findings in court as
an expert witness, then they would also proceed to
do so.
* The work is much like that of a crime scene
examiner but with fewer bodies and better hours and
generally much higher pay.

Forensic Taphonomy
Zach Hasenyager
What is it?



Study of the history of a body after death
Affects estimates of time since death, ID of
the body, and ability to determine cause and
manner of death
Examines the decomposition of a body after
death from individual, cultural, and
environmental factors.
Education Needed
Forensic Taphonomy is very broad
Archaeology/Biology/Earth Sciences
are all useful
Types of Evidence
Taphonomic Evidence
-Individual factors
-Age, sex, body weight, properties of bones, cause of death
-Cultural factors
-Burial Practices
-Allterations due to unusual circumstances
-War
-Environmental factors
-Temperature-Higher temps. Means more
decomposition
-Moisture Content
-pH levels
-Properties in the soil
Forensic Entomology
Maria Andrews
Forensic Entomology



Entomology: the study of insects.
Forensic Entomology: the study of
insects associated with a dead body.
After 72 hours, entomological evidence is the most accurate,
and often the only way to determine the time since death.
Can be used to determine if body has been moved after death,
whether it was disturbed, the presence of position of wound
sites, and whether the victim used drugs or was poisoned.
Do NOT work fulltime in a crime lab, but mostly in research and
teaching (most are research scientists)
Education Needed




B.Sc. In biology, zoology, or entomology
Followed by an M.Sc. and Ph.D. in
entomology, preferably in forensic
entomology, insect ecology, and taxonomy.
Five years in case work are required following
the Ph.D.
Most active forensic entomologists are
university professors, and conduct ongoing
research.
Example of Evidence



Drugs: because insects feed on body
tissues, they also feed on any unnatural
substances in the victim’s body,
including alcohol, drugs, or poison.
Insect is likely to be affected by poison
or drugs.
Analysis of the insect can often reveal
the toxin, when body is severely
decomposed.

Forensic Psychiatry
Forensic Psychiatry
Description

Forensic Psychiatry involves the
assessment and evaluation of
individuals rather than the treatment of
psychiatric patients, although there is
occasional involvement with treatment
of criminal offenders. Treatments are
limited to the assessment of individuals
involved in legal matters.
Three major subgroups
There are three different types of
forensic psychiatry:
Criminal forensic psychiatry
Civil forensic psychiatry
Administrative forensic psychiatry

Administrative Forensic
Psychiatry

Administrative forensic psychiatry
addresses confidentiality, privileged
communications, privacy issues,
patients rights to treatment or the right
to refuse treatment, and newer
considerations involving commitment or
involuntary hospitalization.
Civil Forensic Psychiatry

Civil forensic psychiatry encompasses
personal injury cases, domestic
relations matters, and competency
issues.
Criminal Forensic Psychiatry

Criminal forensic psychiatry emphasizes
the competency to stand trial, legal
insanity, sentencing issues, and
treatment of the mentally ill offender.
Education


A board certified psychiatrist (M.D. plus
residency)
For an individual to be certified in
forensic psychiatry, the person must
take a 1 year accredited program of
training in forensic psychiatry. There
are over 25 accredited programs in the
U.S.
Case
Example
A serial murderer was also suffering from

dissociative identity disorder. The man was
accused of killing four prostitutes, but had no
memory of the killing. He had a rich fantasy
life, but was found to have a number of
distinct personalities, one of which was
amoral and homicidal. Once he learned of his
murderous tendencies, he agreed to spend
his life in a hospital or prison. Through a
diagnosis, other alternative personalities
emerged. With the help of psychiatric
treatment, the alters were combined into one
personality. He rests comfortably in prison,
thus preventing the homicidal alter to
emerge.
