CHAPTER 1: Crime Scene Investigation of Biological Evidence
1. Which of the following is the first step in crime scene
investigation involving biological evidence?
A. Collection of biological samples
B. Securing the crime scene
, C. Analysis of biological evidence in the laboratory
D. Interviewing witnesses
Correct Answer: B
Rationale: Securing the crime scene ensures that the evidence
remains uncontaminated, preventing potential loss or alteration
of biological evidence.
2. In which of the following scenarios would biological evidence
be most likely to be found at a crime scene?
A. A robbery where no physical altercation occurs
B. A shooting incident with a struggle involved
C. A fraud case involving documents
D. A vehicle theft with no suspects present
Correct Answer: B
Rationale: Biological evidence, such as blood or bodily fluids, is
most likely to be found in crimes involving physical
altercations, such as shootings.
3. Which of the following is a critical factor in the preservation of
biological evidence at a crime scene?
A. Time of day when the crime occurred
