What is the main advantage of using total station surveying equipment at a crime scene?
Answer: It provides highly precise electronic measurements for scene mapping without physical tape measures
A total station uses electronic distance measurement to provide highly precise coordinates for scene mapping, reducing human measurement error.
When documenting injuries on a deceased victim, which technique is recommended to include an anatomical reference?
Answer: Use a body diagram (anatomical chart) in conjunction with photographs to mark injury locations
Using a body diagram alongside photographs provides a clear anatomical reference that helps map the exact location of each injury.
Which statement best describes proper documentation of negative evidence?
Answer: The absence of expected items (e.g., no signs of forced entry) should be noted in the report
Documenting the absence of expected evidence (negative evidence) can be as significant as documenting what is present.
Why must a CSI document the scene before collecting any fingerprints using powders or chemicals?
Answer: Powders and chemicals can alter or destroy the appearance of the original surface and evidence
Latent print development techniques can alter or destroy the original surface appearance, so thorough documentation must precede any enhancement.
What is the purpose of including a north arrow on a crime scene sketch?
Answer: To orient the sketch in relation to true or magnetic north for geographic context
A north arrow orients the sketch geographically, helping future reviewers understand how the scene aligns with its surroundings.
A CSI is the only person at a scene and must photograph, sketch, and take notes simultaneously. What is the recommended priority order?
Answer: Photographs first, then sketch, then notes
Photographs should be taken first to capture the undisturbed scene, followed by sketches with measurements, and then detailed notes.
Which of the following is a best practice when labeling evidence markers (numbered placards) in crime scene photographs?
Answer: Place markers adjacent to evidence so they do not obscure the item
Evidence markers should be placed adjacent to, not on top of, items so they identify each piece without obscuring its appearance or position.
