CSI Investigative Reporting & Documentation 2 — Questions and Answers
Question 1: Which element is most critical when documenting witness statements in a security investigation?
- Summarizing the witness's account in the investigator's own words
- Recording verbatim quotes alongside the investigator's paraphrase
- Noting the exact time, date, and location where the statement was taken (Correct answer)
- Obtaining the witness's social security number for verification
Correct answer: Noting the exact time, date, and location where the statement was taken
Documenting the exact time, date, and location establishes foundational context and chain of custody for the statement.
Question 2: When an investigator discovers new evidence after submitting a preliminary report, the correct action is to:
- Discard the preliminary report and start fresh
- Issue a supplemental report documenting the new findings (Correct answer)
- Verbally inform the client without updating written records
- Amend the original report by overwriting the existing content
Correct answer: Issue a supplemental report documenting the new findings
A supplemental report preserves the integrity of the original report while formally documenting newly discovered evidence.
Question 3: In investigative documentation, 'chain of custody' primarily refers to:
- The hierarchy of authority within the investigative agency
- The chronological order in which suspects are interviewed
- The documented transfer and handling of physical evidence (Correct answer)
- The sequence of approval signatures on a final report
Correct answer: The documented transfer and handling of physical evidence
Chain of custody tracks every person who handled evidence and when, ensuring admissibility and preventing tampering claims.
Question 4: A CSI investigator preparing a report for litigation should write in:
- First person to demonstrate personal accountability
- Third person to maintain professional objectivity (Correct answer)
- Second person to address the reader directly
- Passive voice exclusively to obscure the author's identity
Correct answer: Third person to maintain professional objectivity
Third-person writing in investigative reports maintains professional neutrality and objectivity required for legal proceedings.
Question 5: Which type of photograph is most important to capture first at an incident scene?
- Close-up photos of specific evidence items
- Wide-angle overview shots establishing scene context (Correct answer)
- Photographs of witnesses present at the scene
- Photos of the investigator conducting the examination
Correct answer: Wide-angle overview shots establishing scene context
Wide-angle overview shots establish the overall scene context before items are moved or disturbed during the investigation.
Question 6: The purpose of an executive summary in an investigative report is to:
- Replace the full report for low-priority cases
- Provide a detailed technical analysis of all findings
- Give decision-makers a concise overview of key findings and conclusions (Correct answer)
- List all evidence collected in chronological order
Correct answer: Give decision-makers a concise overview of key findings and conclusions
An executive summary distills the report's essential findings and conclusions for stakeholders who need quick, actionable information.
Question 7: When documenting a scene sketch, which information is mandatory to include?
- Investigator's personal opinion of what occurred
- Scale or legend, north arrow, date, and case number (Correct answer)
- Names and addresses of all potential suspects
- Weather conditions at the time of the incident
Correct answer: Scale or legend, north arrow, date, and case number
Scale, legend, north arrow, date, and case number are required elements that make a scene sketch legally valid and reproducible.
