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

    • True

    • 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.

    What do sharp instruments make?

    • Lacerations

    • Incised wounds

    • Pain

    Correct Answer
    A. Incised wounds
    Explanation
    Sharp instruments make incised wounds. Incised wounds are clean, straight cuts caused by sharp objects like knives, blades, or glass. These wounds have well-defined edges and can penetrate deep into the skin, causing damage to underlying tissues. Unlike lacerations, which are irregular and jagged, incised wounds are typically neat and linear. They often require precise medical intervention, such as suturing, to promote proper healing and minimize scarring. Pain is a common symptom associated with any type of wound, but it is not specific to sharp instrument injuries.

    Hair cuttings:

    • Contain mitochondrial DNA

    • Contain fibers

    • Contain blood samples.

    • Need to calm down.

    Correct Answer
    A. Contain mitochondrial DNA
    Explanation
    Hair cuttings contain mitochondrial DNA. Mitochondrial DNA is a type of DNA that is found in the mitochondria, which are the energy-producing structures within cells. Unlike nuclear DNA, which is inherited from both parents, mitochondrial DNA is inherited only from the mother. Hair cuttings can be a valuable source of mitochondrial DNA for genetic analysis and identification purposes. This is because hair contains cells that have mitochondria, and these mitochondria contain their own DNA. By analyzing the mitochondrial DNA in hair cuttings, scientists can determine maternal lineage and trace ancestry.

    What is altor mortis?

    • The cooling of the body after death.

    • The stiffening of a body after death.

    • Discoloration of the body

    Correct Answer
    A. The cooling of the body after death.
    Explanation
    Algor mortis refers to the cooling of the body after death. After death, the body's temperature gradually decreases until it reaches the ambient temperature. This process occurs due to the cessation of metabolic processes that generate heat in the body. It is one of the signs that forensic experts use to estimate the time of death. The other options, stiffening of the body after death (rigor mortis) and discoloration of the body (livor mortis), are also postmortem changes but refer to different phenomena.

    • True

    • 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.

    • The stiffening of a body after death. 4 hours.

    • Discoloration of the body. 4 hours.

    • Discoloration of the body. Minutes to about an hour.

    Correct Answer
    A. The stiffening of a body after death. 4 hours.
    Explanation
    Rigor mortis is the stiffening of the body after death, caused by chemical changes in the muscles. It typically begins to occur within a few hours after death and reaches its peak around 12 hours. After that, it gradually subsides over the next 24-48 hours. Therefore, the statement "The stiffening of a body after death. 4 hours." is correct as it accurately describes the time frame in which rigor mortis sets in.

    Explanation
    A typical human mouth contains 32 permanent teeth. This includes 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth). These teeth replace the primary (baby) teeth as a person grows and develops. The number 32 is the correct answer because it represents the average number of permanent teeth found in a human mouth.

    Rate this question:

  • 27. 

    True or false: Injury trumps disease when relating to traumatic death.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Injury trumps disease when relating to traumatic death because traumatic deaths are typically caused by accidents or violent events that result in severe injuries, such as car accidents or homicides. In these cases, the immediate physical trauma caused by the injury is the primary cause of death. Diseases, on the other hand, develop over time and may not directly cause immediate death in the same way that a traumatic injury does. Therefore, when comparing the two, injury is considered to have a greater impact on causing a traumatic death.

    The primary purpose of forensic evidence in a criminal trial is to:

    • Figure out what happened.

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

    • Match the evidence to the suspect or victim.

    Correct Answer
    A. 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.

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

    • True

    • False

    Correct Answer
    A. 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.

    What do blunt objects produce?

    • Incisions

    • Lacerations

    • Pain

    Correct Answer
    A. Lacerations
    Explanation
    Blunt objects produce lacerations. When a blunt object strikes the body with force, it can cause tearing or splitting of the skin, resulting in lacerations. Unlike incisions, which are clean, straight cuts typically caused by sharp objects, lacerations are irregular and jagged. Blunt objects can cause deep and severe lacerations, leading to bleeding and potential damage to underlying tissues. Pain is a common result of any injury, including lacerations caused by blunt objects, but it is not the direct product of the blunt object itself.

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

    • Skin

    • A fresh bite into tissues containing lots of muscle

    • Your mom.

    Correct Answer
    A. 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.

    Rate this question:

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

    • Direct evidence

    • Circumstantial evidence

    • Individual characteristic evidence

    • The number 9.

    Correct Answer
    A. 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.

    Explanation
    A criminal trial is not simply a mechanism to secure a conviction against a suspect. It is a legal process that aims to determine the guilt or innocence of the accused based on the evidence presented. The trial involves the examination of witnesses, cross-examination, presentation of evidence, and arguments from both the prosecution and defense. The purpose is to ensure a fair and impartial trial where the truth can be established and justice can be served, whether that means convicting the suspect or proving their innocence.

    • False

    Correct Answer
    A. False
