  1. What is the purpose of a 'finished sketch' as opposed to a rough sketch?

    Answer: It is a polished, to-scale drawing prepared for court presentations

    A finished sketch is a polished, to-scale version of the rough sketch prepared later for use in court presentations and case files.

  2. Which datum point is commonly used as the origin (0,0) in a coordinate-system crime scene sketch?

    Answer: A permanent, immovable reference point such as a door corner or utility pole

    A permanent, immovable reference point is chosen as the origin so the scene can be accurately reconstructed at any future time.

  3. In crime scene notes, what does the abbreviation 'TOA' typically stand for?

    Answer: Time of Arrival

    TOA stands for Time of Arrival, which is a critical timestamp recorded in crime scene notes to document when personnel first reached the scene.

  4. A CSI notices that shell casings were moved before they could be photographed in place. What is the best course of action?

    Answer: Document the current positions, note in the report that they were moved, and identify who moved them

    The CSI must document current positions, note the disturbance in the report, and identify who moved the items to preserve integrity.

  5. What is 'photogrammetry' as applied to crime scene documentation?

    Answer: Using photographs with known measurements to extract precise spatial dimensions

    Photogrammetry uses photographs with known reference measurements to extract accurate distances and dimensions of the scene or evidence.

  6. When documenting a vehicle as a crime scene, which area is typically photographed last in the sequence?

    Answer: The interior and trunk after exterior documentation is complete

    Standard vehicle documentation follows an exterior-first sequence before moving to interior and trunk to avoid disturbing evidence during photography.

  7. What is the risk of using only digital notes (tablet/laptop) without paper backup at a crime scene?

    Answer: Device failure, battery death, or corruption could result in permanent loss of notes

    Electronic device failure at a scene could result in the permanent loss of critical documentation, making a paper backup essential.
