Review
Question 1: According to the National Incident Management System (NIMS), what is
the primary characteristic of a Level 1 incident?
A. It requires only local resources and can be managed by a single jurisdiction.
B. It requires state and federal resources due to widespread damage or mass
casualties.
C. It requires only mutual aid from neighboring jurisdictions.
D. It requires no formal incident command structure.
CORRECT ANSWER: B. It requires state and federal resources due to widespread
damage or mass casualties.
Rationale:NIMS Level 1 incidents are the most severe, involving widespread damage,
mass casualties, or large-scale emergencies that exceed local and state capabilities,
necessitating federal assistance and a unified command structure .
Question 2: When documenting a death scene, which of the following is considered
circumstantial evidence rather than a method of positive identification?
A. DNA analysis
B. Fingerprints
C. Clothing
D. Dental records
CORRECT ANSWER: C. Clothing
Rationale:Positive identification requires scientific methods such as DNA analysis,
fingerprints, or dental records. Clothing is considered circumstantial evidence and is
not sufficient for positive identification on its own .
Question 3: Which of the following items is NOT required in chain of custody
documentation?
A. Date and time of evidence collection
B. Name of the person who collected the evidence
C. Personal observations about the decedent's character
D. Disposition of the evidence
CORRECT ANSWER: C. Personal observations about the decedent's character
Rationale:Chain of custody documentation must include the date and time of
collection, the identity of the collector, and the disposition of evidence. Personal
,observations about the decedent are recorded separately and are not part of chain of
custody records .
Question 4: What is the primary purpose of using a body diagram during death
investigation documentation?
A. To record the decedent's personal history
B. To document the location of injuries and evidence on the body
C. To establish the decedent's identity
D. To determine the cause of death
CORRECT ANSWER: B. To document the location of injuries and evidence on the
body
Rationale:Body diagrams provide a visual record of the location of injuries, wounds,
and evidence, complementing written descriptions and photographs to create a
comprehensive documentation of the decedent's condition .
Question 5: In mass disaster situations, which identification method may be used
as a last resort when all other scientific methods are unavailable?
A. DNA analysis
B. Fingerprint comparison
C. Personal effects and clothing analysis
D. Dental record comparison
CORRECT ANSWER: C. Personal effects and clothing analysis
Rationale:In mass disasters where scientific identification methods are exhausted or
unavailable, personal effects and clothing analysis may be used as a last resort for
identification, though this is considered less reliable than DNA, fingerprints, or dental
records .
Question 6: What does the term "livor mortis" refer to in death investigation?
A. The stiffening of muscles after death
B. The discoloration of skin due to blood pooling in dependent areas
C. The cooling of the body after death
D. The decomposition of tissues by bacterial action
CORRECT ANSWER: B. The discoloration of skin due to blood pooling in dependent
areas
Rationale:Livor mortis, also known as lividity, is the purplish-red discoloration of skin
caused by the gravitational pooling of blood in dependent areas of the body after
circulation ceases. It typically begins within 1-2 hours after death .
Question 7: Which type of evidence is generally considered the most reliable for
positive identification of a decedent?
,A. Visual recognition by family members
B. Personal effects found at the scene
C. Dental x-rays compared to antemortem records
D. Photographs taken at the death scene
CORRECT ANSWER: C. Dental x-rays compared to antemortem records
Rationale:Dental x-rays are highly reliable for positive identification because teeth are
resistant to decomposition and comparison with antemortem dental records provides
scientific certainty. Visual recognition and personal effects are less reliable methods .
Question 8: What does the acronym NIMS stand for in the context of death
investigation and emergency response?
A. National Investigation Management System
B. National Incident Management System
C. National Integration Management System
D. National Incident Mobilization System
CORRECT ANSWER: B. National Incident Management System
Rationale:NIMS stands for the National Incident Management System, a standardized
approach to incident management developed by FEMA that provides a consistent
framework for responding to emergencies across all levels of government .
Question 9: What is the primary purpose of maintaining chain of custody for
evidence collected during a death investigation?
A. To document the decedent's medical history
B. To ensure the integrity and admissibility of evidence in court
C. To determine the cause of death
D. To notify the next of kin
CORRECT ANSWER: B. To ensure the integrity and admissibility of evidence in court
Rationale:Chain of custody documents every person who handled evidence from
collection to court presentation. This continuous documentation ensures evidence
integrity and establishes its admissibility in legal proceedings .
Question 10: In which scenario would a forensic anthropologist be most likely to
assist in a death investigation?
A. A homicide with gunshot wounds to the chest
B. A decomposed, burned, or skeletal remains case
C. An infant death with no visible injuries
D. A drug overdose with clear toxicology findings
CORRECT ANSWER: B. A decomposed, burned, or skeletal remains case
, Rationale:Forensic anthropologists specialize in analyzing decomposed, burned, or
skeletal remains to assist with identification, assess trauma, and estimate postmortem
interval when soft tissue is absent or severely degraded .
Question 11: The legal authority for medicolegal death investigation is established
by which source?
A. Federal law
B. State statute
C. County ordinance
D. International treaty
CORRECT ANSWER: B. State statute
Rationale:The legal authority for death investigation is established by state statute,
which defines the jurisdiction, duties, and powers of medical examiners and coroners
within each state .
Question 12: Which of the following deaths would generally NOT be reportable to
the medical examiner or coroner?
A. A homicide
B. A suicide
C. A natural death under a physician's care with no suspicious circumstances
D. An accidental death
CORRECT ANSWER: C. A natural death under a physician's care with no suspicious
circumstances
Rationale:Natural deaths with no suspicious circumstances, where the decedent was
under appropriate medical care for a disease that could reasonably be expected to
cause death, are generally not reportable. Reportable deaths include unnatural deaths,
sudden unexpected deaths, and deaths under suspicious circumstances .
Question 13: The "dying declaration" is an exception to which legal rule of
evidence?
A. Hearsay rule
B. Best evidence rule
C. Exclusionary rule
D. Miranda rule
CORRECT ANSWER: A. Hearsay rule
Rationale:A dying declaration is an exception to the hearsay rule that allows
statements made by a person who believes they are about to die to be admitted as
evidence in legal proceedings .
Question 14: When photographing a death scene in bright sunlight, what technique
should be used to capture detail in deep shadow areas?
