Questions and Answers

1.

A crime scene will be cordoned off, and sometimes this may be more in than one place or area.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
A crime scene is typically cordoned off to preserve and protect the evidence present at the scene. This helps ensure that the evidence is not contaminated or tampered with, and allows investigators to conduct a thorough examination of the area. In some cases, a crime scene may be large or spread out, requiring multiple cordoned off areas to be established. This helps to maintain the integrity of the investigation and prevent unauthorized access to the scene. Therefore, the statement "A crime scene will be cordoned off, and sometimes this may be more in than one place or area" is true.

A crime scene kit will include: (Select five)
- A.
  
  Permanent marker pens
- B.
  
  Aerosol regent
- C.
  
  Fingerprint brush
- D.
  
  Needles
- E.
  
  Swabs
- F.
  
  Containers
Correct Answer(s)
A. Permanent marker pens
B. Aerosol regent
C. Fingerprint brush
E. Swabs
F. Containers

Explanation
A crime scene kit includes various tools and materials that are essential for collecting and preserving evidence. Permanent marker pens are used to label and mark evidence, ensuring proper identification. Aerosol regent is likely included for the detection and enhancement of latent fingerprints. A fingerprint brush is used to gently dust for fingerprints and collect them for analysis. Swabs are used to collect biological samples such as blood or saliva. Containers are necessary for storing and transporting evidence safely and securely. Needles, however, are not typically included in a crime scene kit as they are not commonly used for evidence collection and preservation.

The basic crime rape kit consists of: (Select four)
- A.
  
  Microscopic slides
- B.
  
  Laser trajectory kit
- C.
  
  Evidence bags
- D.
  
  Fingerprint powder
- E.
  
  Scissors
Correct Answer(s)
A. Microscopic slides
C. Evidence bags
D. Fingerprint powder
E. Scissors

Explanation
The basic crime rape kit consists of microscopic slides, evidence bags, fingerprint powder, and scissors. Microscopic slides are used to collect and analyze any potential biological evidence. Evidence bags are used to properly store and preserve any collected evidence. Fingerprint powder is used to enhance and visualize fingerprints on surfaces. Scissors are included in the kit for cutting and packaging evidence. Laser trajectory kit is not included in the basic crime rape kit as it is used for analyzing bullet trajectories and is not directly related to collecting evidence in a rape case.

Fingerprints are not only used in the hunt for a perpetrator of a crime, but are also used to help identify the victim.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Fingerprints can indeed be used to help identify the victim of a crime. Each person has a unique set of fingerprints, and these can be compared to a database of known fingerprints to determine the identity of the victim. This can be particularly useful in cases where the victim's body is badly damaged or decomposed, making other forms of identification difficult or impossible. Additionally, fingerprints can provide valuable evidence in cases where the victim's identity is already known but there is a need to establish their presence at a particular location or to link them to a specific object or piece of evidence.

It is not unusual for a court to allow digitally taken photographs.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
It is not unusual for a court to allow digitally taken photographs. This statement is false. Courts commonly allow digitally taken photographs as evidence in legal proceedings, especially in today's digital age where most people have access to smartphones with high-quality cameras. Digital photographs can provide clear and accurate visual documentation of a crime scene, injuries, or other relevant evidence. Courts often consider digital photographs as reliable and admissible evidence, as long as they meet the necessary requirements for authenticity and chain of custody.

Chemical pollution at the scene of a crime refers to any type of material/substance that inhibits the investigation for fibres.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Chemical pollution at the scene of a crime can indeed hinder the investigation for fibres. Chemical substances can contaminate the crime scene, making it difficult to collect and analyze fibres for forensic evidence. These chemicals may alter or destroy the fibres, making it challenging to determine their origin or link them to the suspect. Therefore, the statement "True" is correct as chemical pollution can impede the investigation process for fibres at a crime scene.

7.

The autopsy consists of only an internal examination to determine cause and time of death.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because an autopsy involves both internal and external examinations of the body to determine the cause and time of death. It includes examining the organs, tissues, and bodily fluids internally, as well as conducting a visual examination of the body externally. This comprehensive examination helps forensic pathologists gather all necessary information to determine the cause and time of death accurately.

8.

Tissue samples are taken and sent to the toxicology lab to be tested.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Tissue samples are commonly taken and sent to the toxicology lab for testing purposes. This is done to determine the presence and level of toxins or drugs in the body. By analyzing the tissue samples, toxicologists can provide valuable information regarding the cause of illness, death, or any adverse effects. Therefore, it is true that tissue samples are taken and sent to the toxicology lab for testing.

9.

Contact wounds leave a smaller entrance wound and there is bruising from the gun muzzle, along with burning around the wound.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Contact wounds typically leave larger entrance wounds due to the close proximity of the gun muzzle to the body. Additionally, there may be stippling or tattooing around the wound caused by gunpowder particles being deposited on the skin. Bruising and burning are more commonly associated with gunshot wounds from a distance, rather than contact wounds. Therefore, the given statement is false.

Rate this question:
10.

Lividity is when the blood coagulates/pools in the blood vessels, producing a staining of the skin.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Lividity is the process in which blood coagulates or pools in the blood vessels, resulting in a staining of the skin. This occurs after death due to the force of gravity causing the blood to settle in the lowest parts of the body. Lividity is a natural phenomenon that helps forensic experts determine the position of the body at the time of death. Therefore, the given statement that lividity causes staining of the skin is true.

The internal examination is carried out as a surgical procedure, with the most common practice being a Y-shaped cut being made.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The given statement is true. The internal examination is indeed carried out as a surgical procedure, with the most common practice being a Y-shaped cut being made. This surgical procedure is known as an autopsy or post-mortem examination, where a Y-shaped incision is made on the chest and abdomen to access and examine the internal organs. This allows the pathologist to investigate the cause of death and identify any underlying medical conditions or injuries.

Drowning in sea water happens more quickly than in fresh water.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Drowning in sea water does not happen more quickly than in fresh water. The density of sea water is slightly higher than fresh water due to its salt content, which can make it slightly easier to float in. However, the speed at which drowning occurs depends on various factors such as the individual's swimming ability, panic level, and water conditions. Therefore, it cannot be generalized that drowning happens more quickly in sea water compared to fresh water.
