False

Question 4

PRACTICAL HOMICIDE INVESTIGATION is simply a re-emphasis on the basic time-proven methodologies, an appreciation for the investigative process, an understanding of the dynamics of human behavior, and a comprehension of the most current scientific applications. P.H.I. stresses Tactics, Procedures, and Forensic Techniques.

Suicide notes are direct communications indicating an intent to commit suicide. The notes may be
instructional and/or admonishing and often times have mixed emotional content including
positive and negative feelings.

Question 8

FINAL EXIT SUICIDES are victim-facilitated and victim assisted suicides based on the book
Final Exit written by Mr. Derrick Humphrey.

Question 9

Staging a scene occurs when the perpetrator purposely alters the crime scene to mislead and/or
redirect the investigation. The most common type of staging occurs when the perpetrator attempts to make the death appear as a homicide to cover-up a suicide for insurance purposes.

H) All of the above

Question 19

A Miranda Warning must be given to all suspects as soon as you begin talking to them, even if
they're not in custody.

Question 20

In Practical Homicide Investigation we describe the LINKAGE CONCEPT as the goal to
establish a link between the various facets of the crime scene, the victim, physical evidence and the suspect.

Question 21

An incised wound generally has a clean edge. It is longer than it is deep and there isn't any bridging of skin.

Question 22

The most common forms of death due to asphyxia are found in strangulation, suffocation, hanging, drowning and inhalation of poison gas cases.

Question 23

Putrefaction is caused by the micro?organisms and bacteria within the intestinal tract, which escape from the bowel. It is an extremely accurate method of determining the time of death.

Question 24

Post mortem lividity, also referred to as Livor Mortis, is the pooling of blood into the dependent capillaries and veins. Aside from ASSOCIATIVE FACTORS, it is considered to be a very effective factor in determining Time of Death during the early stages of death.

Question 25

Putrefactive gases include, cadaverine, butyl mercaptide, and other mercaptides as well as
hydrogen sulfide and other sulfides.

Question 26

The most effective and practical method of making Estimates of Times of Death are based upon the information derived from the scene. These are referred to as ASSOCIATIVE FACTORS.

Question 27

If the body is warm to the touch, death occurred a few hours earlier. If the body is cold and clammy, the death may have occurred 18 to 24 hours earlier.

Question 28

Identical twins share the same DNA. They are genetic duplicates in that their chromosomes are identical.

Question 29

Question 30

A stab wound is deeper than it is wide and is often associated with internal bleeding.

Question 31

The PSYCHOLOGICAL AUTOPSY is a collaborative procedure involving law enforcement and
mental health experts who attempt to determine the state-of-mind of a person prior to the fatal act.

Question 32

Cadaveric spasm is instantaneous rigor mortis.

Question 33

Another practical and effective method of determining time of death during the early stages is to judge the LOSS OF BODY HEAT. A method recommended by Practical Homicide Investigation, is to place a rubber gloved hand upon some protected portion of the body, as under the armpit.

Question 34

A contact wound structure is an exception to the general configuration of entrance and exit wound structures.

Question 35

An entrance wound is generally smaller than an exit wound.

Question 39

Tattooing or stippling is caused by hemorrhages due to the discharge of burning powder. These
marks cannot be wiped off the skin.

Question 40

Rigor Mortis is the most effective gauge utilized in making a Determination of Time of Death.

Question 41

There are four types of PHYSICAL EVIDENCE. These are: Transient Evidence, Pattern
Evidence, Conditional Evidence, and Transfer evidence.

Question 42

Transient Evidence is temporary in nature. Odors, imprints and indentations in soft of
changing materials (butter, snow, cheese)

Question 43

The application of Toluidine Blue, Methylene Blue, or Azure is an excellent procedure for
diagnosing abrasions, lacerations and other skin disruptions in the perineum and perianal areas.

Question 44

Autoerotic fatalities are accidental deaths, which involve hypoxia (oxygen deprivation), fantasy, and solo sex?related activities. There may be evidence of cross dressing and/or bizarre rituals, including sophisticated sex paraphilias.

Question 45

Pattern Evidence is produced by contact. Blood splatter, glass fracture patterns, tire marks,
furniture position patters, etc.

Question 46

In Gunshot Residue Testing (GSR), the most effective test to determine whether or not the subject handled a firearm is the:

A) Trace Metal Detective Test (TMDT).
B) Neutron Activation Analysis with .05% nitric acid solution swabbing

Question 47

The DNA molecule is found in all living organisms. Therefore, there is fish DNA, frog DNA,
insect DNA, horse DNA, cow DNA, dog & cat DNA, plant DNA, etc.

Question 48

Physical evidence refers to any tangible article, small or large, which tends to prove or disprove a
point in question. It may be used to reconstruct a crime, identify participants, or confirm or discredit an alibi.

Question 49

PETECHIAL HEMORRHAGES are minute blood clots which appear as small red dots in the conjunctivae, as well as certain internal serosal surfaces of the body. This petechia is
considered to be presumptive evidence of a throttling or strangulation death.

Question 50

In Practical Homicide Investigation we recognize the importance of EVIDENCE.
Basically there are four types of evidence; PHYSICAL, TESTIMONIAL, DOCUMENTARY, and BEHAVIORAL.

Question 51

The application of reagents to enhance biological fluids at the crime scene are extremely effective
in locating materials which are not visible to the naked eye.
One of the more effective reagents is Luminal.

Question 52

DNA is found in every nucleated cell of the human body. An example of some of the materials that
can be analyzed for DNA are as follows: Blood, semen with sperm, human tissue, hair with root,
spittle, urine, feces, bone marrow and dental pulp.

Question 53

DNA testing relies on the integrity of the molecule. However, cross contamination of the material
(As in a multiple rape scenario) does not allow for DNA testing.

Question 54

Hangings are always suicidal or accidental as in autoerotic fatalities.

Question 55

DNA testing can be done within hours using a new cutting enzyme which produces light instead of
radioactivity. The process is called chemiluminescence.

Question 56

If there is a limited amount of genetic material, DNA analysis can still be undertaken through a process called Polymerase Chain Reaction (PCR). The basis of PCR is that it
mimics the cell's ability to replicate DNA.

Question 57

When the head strikes a fixed object (i.e. falls), the cerebral contusion will be more severe on the point of the brain which is contralateral from the skin damage. This is referred to as a
contrecoup injury.

Question 58

The pugilistic attitude or distorted position, which a body assumes in fire is caused by the contraction of the muscles due to the pain experienced from the heat of the fire.

Question 59

DNA (Deoxyribonucleic Acid) establishes each and every person as genetically unique.

Question 60

Transfer Evidence is not produced by contact but by transfer as in the Theory of Transfer and
Exchange.

Question 61

The three major categories of Hair evidence fall within the following: Caucasoid, Negroid, and
Mongoloid.

Question 62

In describing different types of lust murders, the organized type of personality is very similar to the psychotic killer.

Question 63

In the investigation of a series of killings, as in serial murder cases, the investigator should concentrate most of his or her efforts on the first established case. This theory is based
upon the premise that the serial killer usually makes most of his mistakes during the first kill.

Question 64

Chemical processes to enhance fingerprints on paper are as follows: iodine fuming, ninhydrin,
silver nitrate and the laser.

bite mark evidence been accepted in the courts.

Question 66

Lust murders are committed by both Organized and Disorganized types of offenders.

Question 67

Criminal Profiling is an excellent substitute for the usual police investigative techniques undertaken during the investigation and saves valuable time for the detective.

Question 71

Piquerism is a sadistic inclination to stab, pierce, or cut oneself. It is masochistic act.

Question 72

In criminal profiling of a lust murder, the profiler is only interested in looking at the crime scene to see what tangible physical evidence is present.
