2. Manner of Death:
(the way in which death was
caused)
Natural – if autopsy reveals a natural disease (ex-
cancer, pneumonia)
Accident – if autopsy reveals something unexplained
(ex- severe head injury with no symptoms of
assault, but victim found near fallen ladder)
Suicide - angle of bullet entry and gun powder residue
indicate that the gun was fired while being held by the
victim (or self inflicted wounds)
Homicide – angle of bullet entry and gun powder
residue indicate that the gun was fired by somone
other than the victim
3. History
o 1248:
o Hsi Duan Yu (book) by Sung Tz’u – how to distinguish drowning
victim from one who was strangled
o Position of ―coroner‖ developed
o 1761:
o Giovanni Morgagni
o Italian anatomist
o Writes On the Seats and Causes of Diseases
o 1910:
o Richard Cabot
o American physician
o Studies 1000 autopsies- doctors are wrong about cause of
death about 40% of the time
4. Importance
In each case, something is learned by
classifying the ―manner of death‖
– Natural: research can be conducted about the
disease
– Accident: this same accident may be prevented
– Suicide: future suicides can be prevented by taking
appropriate measures
– Homicide: the killer can be persecuted if found
5. Special Cases
Drug Overdose –
– Classified as suicide
Assisted suicide –
– classified as ―Suicide‖ (unless otherwise required by state law)
Deaths in which infants/young children die because of
placement in a potentially hostile environment
– (ex: bath tub with water, or being left in a locked car)
– classified asAccident if there is no evidence of intent to harm the child.
Death of infant/fetus due to maternal drug intoxication –
– Can be classified as accident or homicide depending on
whether or not it is deemed ―intentional‖ by a court

14. DESCRIPTION
Evidence that involved any
kind of hair usually
underwent hair analysis
Two kinds of hair analysis
Chemical hair analysis: Used for
retrospective purposes when
certain chemicals cannot be
found in blood or urine
Microscopic analysis: Used for
assessing different
characteristics of hairs and
comparing them to other hairs
of “known sources”
15. IMPORTANT PEOPLE
Murder case of Duchesse de Praslin
Charles de Choiseul-Praslin married Fanny Sebastiani
Had 10 children and lived a fairly happy life together
Had housekeeper named Henriette Deluzy-Desportes
Deluzy later had an affair with Praslin
Fanny insists on getting rid of mistress, but Praslin keeps her for a
bit
August 18, 1847, ~4 am, Fanny is found dead in her bedroom with
slashes across her chest; the room smelled of gunpowder and blood
Inspector Pierre Allard investigated the case
Found a pistol under the bed + realized wife’s head was crushed by a
heavy instrument
Noticed that the Duke’s gun + clothes stained of blood and hair
Took a magnifying glass and compared hairs from the gun and of
Fanny’s
Praslin found guilty and convicted of his wife’s murder
16. IMPORTANT PEOPLE
Francois Goron – First
forensic scientist to use hair
to identify people
Was ordered to investigate the
death of an unknown victim
At the time, scientists could not
differentiate between animal
and human hair yet
Goron was then able to discover
that the hair had been dyed and
identified the owner
Eventually led to the arrest of
the alleged killer
17. SIGNIFIGANCE
Fairly easy practice of
magnifying hair strands and
comparing the structures
Low cost
Can be used as a replacement
for blood or urine tests + lasts
much longer
Ability to measure a large
number of toxins or other
chemicals
To see whether or not absorbed
poisons link to behavioral / health
problems

25. What is forensic anthropology?
• Anthropology—the study of
humankind (in every aspect, including
culturally, biologically, archeologically, an
d linguistically. Anthropos means "man."
Logy stands for the "science of".)
• Forensic Anthropology—focuses on the
study of the human skeleton to identify
unknown remains that show evidence of
a crime
26. The Development of
Forensic Anthropology
1878—Thomas Dwight's "The
Identification of the Human Skeleton: A
Medicolegal Study" describes that the gender
and stature characteristics of humans were
determinable by examination of the bones
themselves.
1957—The growth stages of skeletal bones
are identified by Americans Thomas
Mocker and Thomas Stewart, forming
the basis of forensic anthropology.
27. Webster–
Parkman Case
(1849)
1849— John Webster and George Parkman were both
Harvard professors. In November, Dr. Webster had
disappeared. The chief witness Ephraim Littlefield revealed
the vault in the medical school which contained some
human remains. Most of it had been partially cremated,
and so dental and skeletal fragments were used to identify
the remains. It was Dr. Parkman. In November 23, John
Webster was convicted for murder, and was hanged in
August.
28. The Murder of Louisa
Bicknese
1897—Adolph Luetgert, a sausage
manufacturer, claimed his wife ran
away. His factory was searched. His
wife's rings, a corset, and several
bones.George Dorsey was one of the
first Forensic expert to lead a forensic
Anthropology investigation. He
concluded that Luetgert murdered his
own wife.
29. Importance of Forensic
Anthropology
With Forensic Anthropology, as long as
there are bones, it is possible to determine
whether or not a crime has taken place.
Forensic Anthropologysolves
what is unknown
about unidentified individuals by analyzing greatly
decomposed remains.
What Forensic Anthropology can
determine about an
individual: age, sex, stature, ancestry, race,
cause of death, health condition before
death
Without Forensic Anthropology, there would be more
unidentified victims, more unsolved crimes. It is important in
both legal and humanitarian contexts. It is needed to solve the
final pieces and bring closure to affected families
32. •AFIS-Automated Fingerprint Identification System
•Was launched on July 28, 1999.
•A national fingerprint and criminal history system that matches
unknown fingerprints against a database to identify criminal and
suspects.
•Primarily used by law enforcement agencies and is controlled by the
FBI.
33. Henry Classification System
•Developed by Sir Edward Henry
•Developed in the late 19th century for criminal
investigations in British India
•First progression towards the modern AFIS system

•The computer then narrows the search down to possible matches
known as candidates.
•The examiner then compares each canidate individually to make
a possible match.
•Even if the examiner declares a “match” in the system they
typically have to get a copy of the record from the state for a final
35. AFIS was developed by the FBI during the late nineties in
order to make criminal classification more effective and
efficient.
Errors:
•Though this system is key to tracking down criminals and
convicting the guilty, many people has tired to get around it,
by changing their fingerprints.
•Some criminal has attempted to change their fingerprints
36. •AFIS allows law enforcement a fast and efficient way to
identify and connect criminals to evidence.
•The average response time for an electronic criminal
fingerprint submission is about 27 minutes, while electronic
civil submissions are processed within an hour and 12
minutes.
•Prior to this time, the processing of ten-print fingerprint
submissions was largely a manual, labor-intensive process,
taking weeks or months to process a single submission.
38. WHAT?
Integrated Ballistics Identification System
Built for the forensic identification of ballistic
information
Saves and searches for matches on bullets and
casings as well as the previous cases they’ve been
involved in
Replaced the painstaking task of identification
by examination by experts
39. People
―Forensic Technology‖ created IBIS in 1991 to
examine and suggest possible matches beyond
human capacity
IBIS is maintained by the Bureau of Alcohol, Tobacco
and Firearms and Explosives
40. Importance
Available in 235 sites nationwide; one in every state
and most major metropolitan areas
Major connections between states and coasts can be
made using this technology that was not possible
before.
42. DNA Profiling -1987
A system of identification using a
sample of an individual’s DNA
DNA is taken
from samples of
blood, saliva,
urine, and semen
to be used as
evidence
43. Back to Bio
• DNA is taken from samples of blood, saliva,
urine, and semen to be used as evidence
• DNA profiling is the gathering, processing, and
analyzing of the unique sequences on the loci
**Bio reminder! Locis are an area on a chromosome**
• Sequences called VNTRs (Variable number
tandem repeats), which are different enough
from person to person to use as identification

101. Why
• Landsteiner was curious to find out why
some people died and some people became
better during blood transfusions
• Discovered that the wrong blood inserted in
one's body can cause death
102. Importance
• Blood transfusions were now possible
• Blood banks were created to preserve blood
for 2-3 week periods to make major
surgeries possible
103. How
• Landsteiner cross tested sera and red cells
from scientists working in his lab, including
his own. His findings revealed that blood
from certain scientists caused the blood of
others to clump, suggesting the existence of
at least two antibody classes.
• Eventually discovered the four types of
blood.
104. What
• Definition: A blood type is a classification of
blood based on the presence or absence of
inherited antigenic substances on the
surface of red blood cells
•
Types: A, B, AB, O
106. What is CODIS?
• “Combined DNA Index System”
• FBI’s program of support for criminal justice
DNA databases as well as the software used to
run these databases
• National DNA Index System (NDIS) is
considered one part of CODIS
▫ Contains the DNA profiles contributed by federal,
state, and local participating forensic laboratories
107. Development
• Outgrowth of the Technical Working Group on DNA
Analysis Methods (TWGDAM)
▫ Developed guidelines for standards of practice in the
United States and Canadian crime laboratories as they
began DNA testing in the late 1980s
• FBI Laboratory began pilot project with six state and
local crime laboratories to develop software to
support each laboratory's DNA testing and allow
sharing of profiles
• The DNA Identification Act of 1994 formally
authorized the FBI to operate CODIS
▫ Did not become fully operational until 1998
109. Importance
• DNA profile of the suspected perpetrator is developed
from the swabs in the kit
• Forensic unknown profile attributed to the suspected
perpetrator is searched against their state database of
convicted offender and arrestee
▫ If there is a match, laboratory will go through procedures to
confirm the match obtain the identity of the suspect
• DNA profile from the evidence also searched against the
state’s database of crime scene DNA profiles
▫ If there is a match, laboratory goes through the
confirmation procedures the match will have linked two or
more crimes together
• Law enforcement agencies involved in these cases are
then able to share the information obtained on each of
the cases and possibly develop additional leads

Editor's Notes
Blood Spatter Analysis [can be defined as] – A field of forensic science that deals with the physical properties of blood and the patterns produced under different conditions as a result of various forces applied to the source of the blood.The blood spatter evidence can reveal information based on the angle of impact, drip pattern, dispersion, wipe pattern, velocity and location of the blood.
Blood Spatter analysis has been studied since the late 1890s, howeverinvestigators haven't always recognized how valuable it can be. It wasn’t until the late 1950s that this evidence began to be used to it’s full potential.There were three main people who were involved in the development of blood spatter research: Doctors Piotrowski, Kirk, and MacDonell.
The first known study of blood spatters occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski. Piotrowski recognized that “It is of the highest importance to the field of forensic medicine to give the fullest attention to bloodstains found at the scene of a crime because they can throw light on a murder and provide an explanation for the essential moments of the incident.”His work has been documented and preserved in the book "Concerning the Origin, Shape, Direction and Distribution of the Bloodstains Following Head Wounds Caused by Blows” in 1895[In the image: the original published copy in German]
Kirk studied the effect of velocity, angle of impact and the combination of the two. Cases that included the interpretation of blood spatters didn't appear until about 50 years after Piotrowski’s original research.In the highly publicized case of the State of Ohio v. Samuel Sheppard in 1955, Dr. Paul Kirk submitted blood spatter evidence, marking one of the earliest instances of the legal system recognizing the importance of blood spatter. Dr. Kirk established the relative positions of the attacker and the victim as well as showing that the attackerstruck the victim with his left hand.
The next significant person in the field was Dr. Herbert MacDonell, who published "Flight Characteristics of Human Blood and Stain Patterns" in 1971. In 1973, MacDonell developed the Bloodstain Evidence Institute, where he trained law-enforcement in blood spatter analysis and developed courses to continue to train analysts. As a result, he is widely recognized as the “father” of bloodstain pattern analysis in the Western hemisphere.In 1983, he and other attendees of the Bloodstain Evidence Institute founded the International Association of Bloodstain Pattern Analysts (IABPA).
Since then, the field of bloodstain analysis has continued to grow and develop. It has now become standard practice for law enforcement to include during crime-scene investigation.Piotrowski recognized that “It is of the highest importance to the field of forensic medicine to give the fullest attention to bloodstains found at the scene of a crime because they can throw light on a murder and provide an explanation for the essential moments of the incident.”
Unknown femaleAt the time of her death, she held onto a chunk of hairFirst classifed the hair as nonhumanGoron later did research on different hairs and fibersGoron’s research led to many more discoveries and studies of different kinds of hair
Chemicals are found to longest impressions in the hair compared to anywhere elsePicture on the right explains how chemicals from the blood travel into our hair
Any surface with marks or writing so if there’s writing on the walls or floor, then that also falls under questioned documents.
Now that we know what questioned documents are, we’re gonna move on to QDE, the process of analyzing those documents. fraud investigation, forgery specialists, forensic stylistics, computer crime investigationEACH ASPECT OF THE DOCUMENT IS EXAMINED materials used to write the documents. What it’s made out of, etc.
Earliest QD examiner is Jean Mabillon. His work would later evolve into QDE.Albert S. Osborn invited some of his colleagues from the US and Canada to talk about and share research on QDE.3 decades, hos books regarded as classics in the field. Had more informal meetings with his colleagues until official formation of ASQDE, the field’s leading organization.
Not only fingerprints, but corresponding criminal histories; mug shots; scars and tattoo photos; physical characteristics like height, weight, and hair and eye color; and aliases.
The Henry Classification System allowed categorization of ten-print fingerprint records into primary groupings based on fingerprint pattern types. Placed fingerprints into categories and did not allow correct classification of individual prints. The Henry Classification System assigns each finger a number according to the order in which is it located in the hand, then assigned a numerical value to fingers that contain a whorl pattern; fingers 1 and 2 each have a value of 16, fingers 3 and 4 have a value of 8, and so on, with the final two fingers having a value of 1. Fingers with a non-whorl pattern, such as an arch or loop pattern, have a value of zero. The value of 1 is added to each sum of the whorls with the maximum obtainable being 32. Thus, the primary classification is a fraction between 1/1 to 32/32 where 1/1 would indicate no whorl patterns and 32/32 would mean that all fingers had whorl patterns
To surgically remove fingerprints doctors cut out your prints and replace it with skin from beneath your foot or in extreme cases doctors replace it with another persons fingerprint. Usually both the doctor and criminal are convicted in the end.

Although no solid evidence can be obtained from this process, it’s a behavioral and investigative tool intended to help investigators to accurately predict and profile the characteristics of unknown criminal subjects or offenders; Thus, guiding the investigation in the right direction. In modern criminology, offender profiling is generally considered the "third wave" of investigative science: 1) study of clues 2) study of crime itself 3) study of the psyche of the criminal.
In the 19th century, J.F., C.L., A.B., H.G. and several others realized the potential of p.p. Except, their research is generally considered to be prejudiced, reflecting the biases of their time. In the 1940s, investigations relied on mental health professionals to create a profile of an offender in order to aid the police investigation. Soon after, J.B. was called upon to analyze the information on the Mad Bomber in New York City, and he created an accurate profile of the offender. This caught the attention of the FBI, who then worked to develop a technique for profiling, based on the process used by Brussel.
Assisted in the autopsy of Mary Kelly. In his notes, he mentioned the sexual nature of the murders coupled with elements of apparent misogyny and rage.

He might even suffer from a condition called Satyriasis, a sexual deviancy that is today referred to as hypersexuality or promiscuity. Bond also mentioned that he believed the offender had no anatomical knowledge and could not be a surgeon or butcher. Dr. Bond later concluded that the same offender was responsible for the murder of Alice McKenzie.

After Howard Teten left the Behavioral Science Unit, John Douglas and Robert Ressler became pillars of offender profiling in the FBI. Spent much time studying convicted sex murderers and interviewing them, creating organized and disorganized typology. ^ Their studies provide more information on the behavioral patterns, traits and characteristics of criminals which can then be added to the offender profiling program.
