Read the first 7 Item Collection flashcards as text

  1. When collecting trace evidence such as hair or fibers from a victim's clothing, which tool is most appropriate?

    Answer: Forceps or tweezers

    Forceps or tweezers allow precise collection of individual trace items without cross-contamination from adhesives.

  2. A wet bloodstain is found on a carpet at a crime scene. What is the proper initial collection method?

    Answer: Absorb with a sterile swab and allow to air dry before packaging

    Wet biological stains should be collected with a sterile swab, air-dried to prevent mold growth, then packaged in breathable paper packaging.

  3. Which of the following best describes 'substrate control' in evidence collection?

    Answer: Collecting a sample of the surface material near but not on the stain

    A substrate control is an unstained sample from the same surface material collected near the evidence to detect background contamination.

  4. When should an evidence technician collect reference standards from a victim?

    Answer: As early as possible during the investigation

    Reference standards from victims should be collected as early as possible to preserve sample integrity and enable comparison analysis.

  5. A firearm is found submerged in water. How should it be transported to the lab?

    Answer: Submitted submerged in the water in which it was found

    Firearms recovered from water should be transported submerged to preserve potential DNA and fingerprints that would be destroyed by drying.

  6. What is the primary purpose of using a bindle when collecting dry trace evidence?

    Answer: To prevent loss of small particles during transport

    A bindle (folded paper packet) secures small trace particles and prevents them from being lost, scattered, or mixed with other evidence.

  7. When collecting soil samples as evidence, what is the recommended minimum number of samples to collect from a questioned area?

    Answer: At least three samples from different areas of the questioned zone

    Collecting at least three samples from different areas of the questioned zone captures variability and provides representative comparison material.
