Question 1

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

Accepted Answer

These terms are used in forensic science to describe the three general categories of human hair characteristics associated with broad ancestral or racial groups, although the use of these terms is becoming less common due to their oversimplification and potential for misunderstanding or misuse.

Question 2

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

Accepted Answer

Organized lust murderers are typically methodical, plan their crimes carefully, and often appear normal or charming, contrasting with psychotic killers who may act impulsively due to their break from reality.

Question 3

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.

Accepted Answer

The theory suggests that a serial killer is more likely to make mistakes during their first crime due to inexperience, providing more evidence for investigators to work with.

Question 4

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

Accepted Answer

The laser is not a chemical process; it is a physical method used to visualize fingerprints.

Question 5

Bite-mark and footwear impression evidence can be individualized and identify a specific
suspect. However, footwear impressions are more specific than bite marks. Only recently has
bite mark evidence been accepted in the courts.

Accepted Answer

Bite mark evidence has been used in courts for a longer period, but both bite mark and footwear impression evidence have faced scrutiny for their reliability in uniquely identifying a specific suspect. The specificity and acceptance of these types of evidence can vary, and recent years have seen more critical evaluation of their use in forensic science.

Question 6

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

Accepted Answer

Both Organized and Disorganized offenders can commit lust murders, as these types of murders are characterized by a sexual element to the crime, which can be a motivating factor for offenders with different levels of organization and planning in their criminal behavior.

Question 7

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

Accepted Answer

Criminal profiling is a supportive tool rather than a substitute for traditional investigative techniques. It aids in narrowing down suspects but does not replace the need for gathering physical evidence, interviewing witnesses, or other fundamental aspects of a criminal investigation.

Question 8

In comparing typologies the organized Offender is most likely to be defined as Psychopathic
while the disorganized Offender is more likely to be described as Psychotic.

Accepted Answer

Organized offenders are often characterized as psychopathic due to their meticulous planning and lack of remorse, while disorganized offenders are more likely to be described as psychotic due to their impulsive actions and possible detachment from reality.

Question 9

There are three types of stalkers. The Psychopathic Personality Stalker, the Psychotic Personality Stalker, and the Erotomania Stalker. The most prevalent of the stalkers fall within the Erotomania classification.

Accepted Answer

Stalking behaviors are complex and can't be neatly categorized into just three types. While erotomania (a delusional belief that another person is in love with the individual) is a recognized motive for stalking, it is not the most prevalent. Stalkers have a variety of motivations and psychological profiles, including those driven by obsession, jealousy, desire for intimacy, or revenge, among others.

Question 10

Evisceration is a sexually sadistic act in which the viscera are cut-out and/or are removed from the abdominal cavity. This type of psychopathology is found in both organized and disorganized offenders.

Accepted Answer

Evisceration can indeed be a manifestation of sexually sadistic behavior, where the perpetrator derives sexual pleasure from the extreme violence of removing internal organs. This type of act can be found in both organized and disorganized offenders, as it reflects a deep-seated psychopathology rather than a specific pattern of criminal behavior. Organized offenders may plan and execute the act with precision, while disorganized offenders might do so impulsively or chaotically.

Question 11

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

Accepted Answer

Piquerism is a sadistic inclination involving the act of piercing or stabbing others, not oneself, which is a form of deriving pleasure from inflicting pain on others.

Question 12

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.

Accepted Answer

In criminal profiling of a lust murder, the profiler is interested in more than just tangible physical evidence at the crime scene. They also consider the behavior of the offender, victimology, and the psychological aspects that may have influenced the crime, to build a comprehensive profile of the perpetrator.

Question 13

In Munchausen Syndrome by Proxy (MSBP) cases, the mother of the child is always the perpetrator of the condition.

Accepted Answer

While mothers are the most commonly identified perpetrators in MSBP cases, fathers or other caregivers can also be responsible for the condition.

Question 14

The sexual sadist derives psychosexual gratification from observing the physical and emotional pain suffered upon himself.

Accepted Answer

A sexual sadist derives psychosexual gratification from inflicting pain, suffering, or humiliation on others, not upon themselves.

Question 15

The average INCLUSION VALUES for protein markers are as follows:
Using the A-B-O System 1 in 3 in the population,
Using the PGM Subtypes 1 in 10 in the population
Using a single DNA probe 1 in 80,000,000 in the population.

Accepted Answer

The values given for the inclusion rates of various genetic markers (A-B-O system, PGM subtypes, and a single DNA probe) are consistent with the general understanding of how common or rare these markers are in the population. The A-B-O blood group system is relatively common, PGM subtypes are less common, and a single DNA probe can be highly specific, leading to a much lower inclusion rate in the population.

Question 16

The serial killer murders his victims over a period of time with time breaks in between the killings called "cooling?off" periods. A killer is classified as serial after two murders.

Accepted Answer

A serial killer is defined as someone who murders three or more people over a period of time, with cooling-off periods between the murders.

Question 17

Munchausen Syndrome by Proxy (MSBP) is the deliberate production or feigning of physical or psychological signs or symptoms in another person, who is under the individual's care.

Accepted Answer

Munchausen Syndrome by Proxy (MSBP) involves a caregiver or guardian inducing or fabricating symptoms in another person, typically their child, to gain attention or sympathy.

Question 18

There are four classifications of SEX RELATED HOMICIDES: 1. Interpersonal violence oriented disputes and assaults.
2) Rape and/or Sodomy oriented assaults.
3. The Lust Murder
4. The Serial killer
The LUST MURDER is the most common type of sex related homicide. TRUE or FALSE

Accepted Answer

The statement is false because lust murders, while highly publicized, are not the most common type of sex-related homicide. Interpersonal violence oriented disputes and assaults are more common.

Question 19

Mucopolysacchrides are ground substance found in abrasions as well as other skin injuries,
especially in sexual assaults. Mucopolysacchrides do not react to reagents such as Toluidine
Blue, Methylene Blue, or Azure.

Accepted Answer

Mucopolysaccharides, found in the ground substance of connective tissue, can indeed react to certain reagents like Toluidine Blue, which is used to highlight areas of injury in sexual assault examinations due to its affinity for acidic tissue components.

Question 20

Blood type can be determined from feces.

Accepted Answer

Blood type can be determined from feces because it contains cells shed from the lining of the intestines, which carry the individual's blood type antigens.
