    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 is the foundation of forensic science and helps investigators determine the presence of evidence at a crime scene. Additionally, scientific testing techniques such as DNA analysis, fingerprint analysis, and ballistics testing are used to gather and analyze evidence. Basic logical reasoning is also essential in connecting the evidence and drawing conclusions. Therefore, the statement is true.

    True or false: Forensic scientists do not need to know anything about the rules of law since that is an area reserved only for students of the law (attorneys, judges, congress, etc.). Attorneys that require an expert witness will tell the expert everything he/she needs to know about the rules of law and what to say in court.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Forensic scientists do need to have knowledge about the rules of law. While attorneys may provide guidance on specific legal aspects, forensic scientists must understand the legal framework within which they operate. This knowledge is important for properly conducting investigations, handling evidence, and presenting findings in court. Forensic scientists often serve as expert witnesses and need to be aware of legal procedures, rules of evidence, and courtroom protocols. Therefore, it is incorrect to say that forensic scientists do not need to know anything about the rules of law.

    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
    Forensic evidence in a criminal trial serves the primary purpose of physically linking the defendant to the crime scene, which in turn provides inferential evidence of their involvement or association with the crime. This evidence helps establish a connection between the defendant and the crime, strengthening the case against them. By presenting forensic evidence, such as DNA, fingerprints, or footprints, the prosecution can demonstrate that the defendant was present at the crime scene, supporting the argument of their guilt. Therefore, the primary purpose of forensic evidence is to provide this physical link, aiding in the establishment of the defendant's commission or association with the crime.

    Courts may require forensic scientists to provide a measurement of a reasoned opinion.  This measurement of a conclusion drawn from scientific data is called the:

    • Percent error

    • Degree of scientific certainty

    • Approximate percentile.

    Correct Answer
    A. Degree of scientific certainty
    Explanation
    Forensic scientists are often required to provide expert opinions based on scientific data in court. This opinion is not expected to be absolute certainty, but rather a measurement of the level of confidence in the conclusion drawn from the data. This measurement is known as the "degree of scientific certainty." It represents the level of confidence that the conclusion is accurate and reliable based on the available evidence and scientific methods. Percent error refers to the accuracy of a measurement, while approximate percentile is not relevant in this context.

    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 muscle tissue is denser and provides more resistance, resulting in a deeper and more defined impression. Additionally, the presence of more muscle tissue would also provide more texture and detail to the bite mark, making it easier to identify and analyze. In contrast, skin alone would not provide as much detail and may not leave a clear impression, while the inclusion of "Your mom" as an option is irrelevant and does not provide any information about the clarity or distinctiveness of a bite mark.

    What is rigor mortis and how long after death does it take for this reaction to happen?

    • 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 that occurs after death. It is caused by a chemical reaction in the muscles that leads to the contraction and hardening of the muscles. This process typically begins within a few hours after death and reaches its peak at around 12 hours. After that, the stiffness gradually diminishes over the next 24-48 hours. Therefore, the correct answer stating that rigor mortis occurs after 4 hours is accurate.

    What do blunt objects produce?

    • Incisions

    • Lacerations

    • Pain

    Correct Answer
    A. Lacerations
    Explanation
    Blunt objects produce lacerations. Lacerations are deep cuts or tears in the skin or flesh caused by a blunt force trauma. Unlike incisions, which are typically clean and intentional cuts made with a sharp object, lacerations are usually irregular and jagged. Blunt objects can cause lacerations by exerting force on the skin and tissues, tearing them apart. This can result in a variety of injuries, ranging from minor cuts to more severe wounds that may require medical attention. Pain is a common result of lacerations, but it is not exclusive to blunt objects and can be associated with various types of injuries.

    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 refers to evidence that requires the inference of one fact from another fact that has been proven in court. Unlike direct evidence, which directly proves a fact, circumstantial evidence relies on indirect clues or circumstances to establish a conclusion. This type of evidence is often used when there is no direct witness or conclusive proof available. Therefore, circumstantial evidence is the correct answer as it always requires inference from a proven fact in court.

    • Taking notes

    • Taking photographs

    • Sketching the crime scene

While videotaping can provide a visual record of the scene, it may not capture all the necessary details or angles. Taking notes allows for written documentation of important information, while taking photographs and sketching the crime scene provide additional visual evidence that can be used for analysis and investigation. Therefore, none of the above options are acceptable substitutes for videotaping at a crime scene.
