Question 1

Which one of the following items is not considered trace evidence?
A) Latent fingerprint
B) chip of glass
C) firearm
D) fiber
E) hair follicle

Accepted Answer

Trace evidence is any physical evidence that can be transferred from one person, object or location to another, leaving behind a trace. Latent fingerprints, chips of glass, fibers, and hair follicles are all examples of trace evidence. Firearms, however, are not considered trace evidence as they are not easily transferred from one location to another and are more likely to be considered physical evidence.

Question 2

While Jenkins and Chang were lifting trace evidence from the driver's side compartment, what other piece of evidence revealed itself?
A) shell casing
B) tooth fragment
C) apparent blood stain
D) foot print
E) spent bullet

Accepted Answer

E

Question 3

What was the reason for measuring certain dimensions around the driver's side seat compartment?
A) could provide information about who may been driving the vehicle
B) could provide DNA evidence
C) could provide a source of trace evidence
D) could provide information about why she loaned her boyfriend her car
E) could provide information why a bullet was found on the driver's side floorboard.

Accepted Answer

Measuring certain dimensions around the driver's side seat compartment can help in determining the size or position of the person who was driving the vehicle, which can be crucial in investigations to narrow down suspects or understand the circumstances around an incident.

Question 4

The Madawaska case that Lt. Jenkins retold to Miss Chang involved…
A) Locard principle
B) paint chips
C) hair samples
D) all of the above
E) choice 'a' & 'c' are correct

Accepted Answer

The Madawaska case involved the Locard principle, paint chips, and hair samples, making all of the above choices correct.

Question 5

What was discovered in the back of the vehicle?
A) large stained area, a pattern stain, and trace evidence
B) large stained area, another shell casing, and fingerprints
C) large stained area, spent bullet, pattern stain
D) large stained area, footprint, fingerprints
E) large stained area, skeletal remains, cell phone

Accepted Answer

The correct answer is A) large stained area, a pattern stain, and trace evidence because it encompasses a broad range of possible findings without specifying items that would typically require more specific circumstances or additional context to be found together.

Question 6

Jenkins prior partner Juarez was….
A) a corrupt officer
B) tried to kill Jenkins
C) involved in drugs
D) serving time in prison

Question 13

What is trace evidence?
A) objects clearly visible to the naked eye.
B) objects that often are not visible to the naked eye.
C) fiber, grains of dirt, chips of paint, specks of pollen
D) all of the above
E) choice "b" & "c"

Accepted Answer

Trace evidence refers to small, often microscopic, pieces of physical evidence that can be transferred during a crime. This can include fibers, grains of dirt, chips of paint, and specks of pollen, which are often not visible to the naked eye. Therefore, choice "b" and "c" are accurate descriptions of trace evidence, making "E" the best answer.

Question 14

Which one of the microscopes provides the highest degree of magnification?
A) hand lens
B) optical or light microscope
C) binocular or dissection scope
D) transmission electron microscope (TEM)
E) scanning electron microscope (SEM)

Accepted Answer

The transmission electron microscope (TEM) provides the highest degree of magnification among the given options. It can magnify up to 1 million times, allowing visualization of ultrafine details in specimens. The other microscopes listed have lower magnification capabilities.

Question 15

The anchor point where a hair grows from the scalp is referred as the……
A) cuticle
B) cortex
C) medulla
D) follicle
E) shaft

Accepted Answer

The anchor point where a hair grows from the scalp is called the follicle. The cuticle is the outer layer of the hair shaft that protects the inner layers. The cortex is the middle layer of the hair shaft that gives it its structure and color. The medulla is the innermost layer of the hair shaft that is sometimes absent. The shaft is the visible part of the hair above the scalp.

Question 16

The medullary index is the …
A) cuticle portion of the hair shaft
B) cortex portion of the hair shaft
C) ratio of the width of the medulla to the width of the hair shaft
D) ratio of the depth at the follicle is embedded into the scalp to the length of the hair shaft
E) history of the person's drug intake

Accepted Answer

The medullary index is a measure of the width of the medulla (the central core of the hair shaft) compared to the width of the hair shaft. It is calculated by dividing the width of the medulla by the width of the hair shaft. The medullary index is used in forensic science to help identify human hair samples, as the medullary index can vary between different people, races, and even between different hairs on the same person.

Question 17

Which one of the following term is not considered when examining fiber evidence.
A) twist
B) delusterants
C) color
D) width
E) medullary index

Accepted Answer

The medullary index is not considered when examining fiber evidence. The other options, including twist, delusterants, color, and width, are all important factors when analyzing fiber evidence. The twist of a fiber can give insight into the method of production, while delusterants can affect how a fiber appears under certain lighting conditions. Color and width can also provide valuable information about the origin and potential sources of the fiber.

Question 18

When viewing a prepared slide using a light microscope what lens do you initially start with?
A) low power
B) medium power
C) high power
D) oil immersion lens
E) none of the above

Accepted Answer

When viewing a prepared slide with a light microscope, it is best to start with the lowest magnification, which is the low power lens. This allows for a larger field of view and easier location of the specimen.

Question 19

Which of the situations would involve the Locard Exchange Principle?
A) shaking hands
B) walking through mud
C) petting an animal
D) shampooing a carpet
E) All of the above

Accepted Answer

The Locard Exchange Principle states that every contact leaves a trace, meaning that any interaction between two objects or individuals will leave some form of evidence behind. Shaking hands, walking through mud, petting an animal, and shampooing a carpet all involve some form of contact which could potentially leave traces of evidence behind, making them all examples of situations that would involve the Locard Exchange Principle.

Question 20

A light microscope has the ocular (eyepiece) marked on the outer perimeter with the number 10x. What does this mean?
A) indicates the resolution capability
B) indicates the size of the ocular (eyepiece)
C) indicates the length of the lens
D) indicates the magnification
E) none of the above

Accepted Answer

The number 10x marked on the ocular of a light microscope indicates the magnification, meaning that the object being viewed will appear 10 times larger than its actual size.
