    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Forensic evidence is not always presented in court as an absolute match to a given suspect or individual. The presentation of forensic evidence in court is subject to interpretation and analysis by experts, and there is often a degree of uncertainty involved. Forensic evidence is typically presented as a piece of the puzzle that supports or contradicts a hypothesis or theory, rather than providing a definitive conclusion. It is important for the court to consider the limitations and potential errors associated with forensic evidence before making any judgments or decisions.

      Figure out what happened.

    • B.

      To physically link the defendant to the crime scene, thereby providing inferential evidence of his/her commission or association with the crime

    • C.

      Match the evidence to the suspect or victim.

    Correct Answer
    B. To physically link the defendant to the crime scene, thereby providing inferential evidence of his/her commission or association with the crime
    Explanation
    The primary purpose of forensic evidence in a criminal trial is to physically link the defendant to the crime scene, thereby providing inferential evidence of his/her commission or association with the crime. Forensic evidence such as fingerprints, DNA samples, or footprints can establish a connection between the defendant and the crime scene, strengthening the case against them. This evidence helps to establish the defendant's presence at the scene and can be used to infer their involvement in the crime. Matching the evidence to the suspect or victim is also important but not the primary purpose of forensic evidence in a criminal trial.

  • 26. 

    Which of the following types of evidence always requires inference of one fact from a fact that has been "proven" in court?

    • A.

      Direct evidence

    • B.

      Circumstantial evidence

    • C.

      Individual characteristic evidence

    • D.

      The number 9.

    Correct Answer
    B. Circumstantial evidence
    Explanation
    Circumstantial evidence always requires inference of one fact from a fact that has been "proven" in court. Unlike direct evidence, which directly proves a fact, circumstantial evidence relies on indirect facts or circumstances to infer a conclusion. It involves connecting the dots and drawing logical inferences based on the evidence presented. This type of evidence is often used when there is no direct evidence available, but the circumstances surrounding the case strongly suggest a certain conclusion.

    True or false: Scientific crime scene investigation is based on the Locard transfer theory of physical evidence, scientific testing techniques, and basic logical reasoning.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Scientific crime scene investigation is indeed based on the Locard transfer theory of physical evidence, scientific testing techniques, and basic logical reasoning. The Locard transfer theory states that whenever two objects come into contact, there is a transfer of materials between them. This theory forms the basis of collecting and analyzing physical evidence at a crime scene. Additionally, scientific testing techniques, such as DNA analysis and fingerprint examination, are used to gather further evidence. Basic logical reasoning is also applied to connect the evidence and draw conclusions about the crime. Therefore, the statement "Scientific crime scene investigation is based on the Locard transfer theory of physical evidence, scientific testing techniques, and basic logical reasoning" is true.

    Autopsies in the United States may be conducted over the objections of next of kin if the medical examiner or coroner deems it necessary to determine the cause of death. This means that even if the family or next of kin objects on personal, moral, or religious grounds, the medical examiner or coroner has the authority to proceed with the autopsy if they believe it is crucial for determining the cause of death.

This means that coroners are responsible for investigating deaths and determining the cause and circumstances surrounding them. They have the authority to conduct autopsies, gather evidence, and interview witnesses in order to establish the facts surrounding a death. This duty is important for ensuring that deaths are properly investigated and any potential criminal activity or negligence is identified.

    Which of the following forensic fields studies disease, disease causes, and diagnosis of disease?

    • A.

      Toxicologist

    • B.

      Entomology

    • C.

      Pathology

    • D.

      Nursing

    Correct Answer
    C. Pathology
    Explanation
    Pathology is the correct answer because it is the forensic field that specifically focuses on studying diseases, their causes, and the diagnosis of diseases. Pathologists analyze tissue samples, perform autopsies, and investigate the nature and origin of diseases. They play a crucial role in identifying the cause of death in forensic investigations and provide valuable insights into the impact of diseases on individuals and populations.

    Autopsy reports generally consist of at least internal and external examination of the body

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Autopsy reports typically involve both internal and external examinations of the body. These examinations are conducted to thoroughly investigate the cause and manner of death. The external examination involves observing and documenting any visible injuries or abnormalities on the body's surface. The internal examination, on the other hand, involves dissecting the body and examining the organs, tissues, and other internal structures to identify any underlying diseases or injuries. Both of these examinations are crucial in providing a comprehensive understanding of the circumstances surrounding the individual's death.

    A coroner is the same thing as either a medical examiner or a pathologist.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    A coroner is not the same thing as a medical examiner or a pathologist. While all three roles are involved in investigating deaths, they have different responsibilities. A coroner is an elected or appointed official who determines the cause and manner of death, often based on information gathered from various sources. On the other hand, a medical examiner is a licensed physician, usually a forensic pathologist, who performs autopsies and determines the cause of death based on medical evidence. A pathologist, on the other hand, is a medical doctor who specializes in the study of diseases and may perform autopsies but is not necessarily involved in determining the cause of death in forensic cases.

    Reviewing witness statements prior to autopsy allows pathologists to construct a testable hypothesis regarding cause of death.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Reviewing witness statements prior to autopsy allows pathologists to gather information about the circumstances surrounding the death. This information can help them form a hypothesis about the cause of death, which can then be tested through the autopsy process. By considering witness statements alongside physical evidence, pathologists can gain a more comprehensive understanding of the case and make a more accurate determination of the cause of death. Therefore, the statement is true.

    A virus can be transmitted from dried blood.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A virus can be transmitted from dried blood because some viruses can remain viable outside the body for a certain period of time. Dried blood can still contain active viruses, and if it comes into contact with an open wound or mucous membranes, it can lead to transmission of the virus to another person. Therefore, it is important to handle dried blood with caution and follow proper infection control measures to prevent the spread of viruses.

    Only bite marks made in human tissue can be analyzed to determine the identity of the biter.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Bite marks made in human tissue are not the only ones that can be analyzed to determine the identity of the biter. Bite marks made in other materials such as food, objects, or even animal tissue can also provide valuable information for analysis. Therefore, the statement that only bite marks made in human tissue can be analyzed to determine the identity of the biter is false.

    Poorly defined bite marks associated with possible tearing of tissue and frequently occurring as multiple bites are typically representative of:

    • A.

      Offensive bite marks

    • B.

      Defensive bite marks

    • C.

      Struggle bite marks

    • D.

      Vampire kisses

    Correct Answer
    B. Defensive bite marks
    Explanation
    Poorly defined bite marks associated with possible tearing of tissue and frequently occurring as multiple bites are typically representative of defensive bite marks. Defensive bite marks are often inflicted by the victim while trying to defend themselves against an attacker. The lack of clarity in the bite marks and the presence of tissue tearing suggest a struggle or resistance during the attack. Offensive bite marks, on the other hand, would be more defined and intentional, while struggle bite marks would show signs of both the attacker and victim's actions. Vampire kisses is not a valid explanation as it is not a recognized forensic term.

    The most reliable antemortem dental records are the x-rays of the teeth.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    X-rays of the teeth are considered the most reliable antemortem dental records because they provide detailed and accurate information about the structure and condition of the teeth. X-rays can reveal dental abnormalities, previous dental treatments, and unique features that can help in identifying an individual. Additionally, dental x-rays can be compared with postmortem dental records to establish a positive identification, making them a valuable tool in forensic dentistry.

    Any licensed dentist may act as a forensic dentist.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Any licensed dentist may act as a forensic dentist because forensic dentistry involves the application of dental knowledge and expertise to legal matters, such as identifying human remains through dental records or analyzing bite marks. As long as a dentist is licensed and has the necessary training and experience in forensic dentistry, they can perform the required tasks and provide expert opinions in legal cases. Therefore, it is true that any licensed dentist may act as a forensic dentist.

    Which of the following would likely be the most clear and distinct bite mark?

    • A.

      Skin

    • B.

      A fresh bite into tissues containing lots of muscle

    • C.

      Your mom.

    Correct Answer
    B. A fresh bite into tissues containing lots of muscle
    Explanation
    A fresh bite into tissues containing lots of muscle would likely be the most clear and distinct bite mark because the presence of muscle tissue provides a firm and resilient surface for the teeth to leave a clear impression. Skin is more pliable and may not retain the same level of detail, while the mention of "Your mom" is unrelated and does not contribute to the clarity or distinctiveness of a bite mark.

    The number of permanent teeth found in a typical human mouth is

    • A.

      26

    • B.

      32

    • C.

      36

    • D.

      42
