COMPREHENSIVE PRACTICE QUESTIONS
Section 1: Investigation & Evidence Fundamentals
1. During an investigation, you obtain a copy of a subject's bank statement without a
subpoena because the branch manager is a personal friend. What investigative principle does
this violate?
A) The hearsay rule
B) Chain of custody and lawful access
C) Best evidence rule
D) Double jeopardy
Answer: B
Rationale: Using personal relationships to bypass legal process breaks the chain of custody and
may render evidence inadmissible. Lawful access to records is essential in any investigation.
Evidence obtained improperly through personal relationships rather than proper legal channels
can compromise the integrity of the investigation and result in evidence suppression .
2. At an administrative hearing, a witness testifies that "the investigator before me said he
saw fraud." This testimony is most likely considered:
A) Direct evidence
B) Hearsay and likely inadmissible
, Page 3 of 128
C) A spontaneous statement
D) A business record exception
Answer: B
Rationale: Out-of-court statements offered for the truth of the matter are hearsay. An
investigator must have personal knowledge of the facts or a proper exception to testify.
Testifying about what another investigator said is hearsay and generally inadmissible. Direct
evidence requires firsthand observation and knowledge of the event in question .
3. An Investigator observes a suspect leaving a building with stolen property. This observation
would be classified as what type of evidence?
A) Circumstantial evidence
B) Hearsay evidence
C) Direct evidence
D) Character evidence
Answer: C
Rationale: Direct evidence is evidence that directly proves a fact without requiring inference.
Observing a suspect leaving a building with stolen property directly proves possession of stolen
goods. Circumstantial evidence (A) requires inference to connect a fact to a conclusion. Hearsay
(B) is out-of-court statements. Character evidence (D) relates to a person's reputation or
character traits .

4. You discover a vendor invoice that was paid twice. The vendor denies refunding the
duplicate payment. Which document is most critical to establish the duplicate payment?
A) The employee's vacation schedule
B) The cancelled checks and bank statements
C) The vendor's tax returns
D) The employee's performance review
Answer: B
Rationale: Cancelled checks and bank statements provide objective documentary evidence that
two payments were actually made. Documentary evidence is essential in fraud investigations.
Employee schedules (A) and performance reviews (D) are not directly relevant. Tax returns (C)
may provide supporting information but are not the most critical documents for proving
duplicate payment .
5. Which principle requires that original documents be used as evidence when available?
A) Parol evidence rule
B) Best evidence rule
C) Exclusionary rule
D) Plain view doctrine
Answer: B
Rationale: The Best Evidence Rule requires that original writings, recordings, or photographs be
used as evidence when available, rather than copies or secondary evidence. This ensures
