Competency-Based Assessment Preparation
Question 1: Which of the following is the PRIMARY responsibility of a medicolegal
death investigator upon arrival at a death scene?
A. Determining the legal cause of death
B. Collecting all physical evidence for laboratory analysis
C. Securing and documenting the scene while preserving evidence integrity
D. Interviewing all witnesses before law enforcement arrives
CORRECT ANSWER: C. Securing and documenting the scene while preserving
evidence integrity
RATIONALE:The medicolegal death investigator's primary role at a death scene is to
secure, observe, and document the scene while ensuring evidence integrity is
maintained. Determining cause of death is the medical examiner's or coroner's
responsibility, evidence collection is often collaborative with law enforcement, and
witness interviews are typically coordinated with investigating officers to avoid
contamination of testimony.
Question 2: When documenting a deceased individual's position at a death scene,
which method provides the MOST accurate and reproducible record?
A. Written description using directional terms only
B. Photographs taken from a single vantage point
C. Triangulation measurements from two fixed points combined with photography
D. Sketching the position freehand without measurements
CORRECT ANSWER: C. Triangulation measurements from two fixed points
combined with photography
RATIONALE:Triangulation measurements from two fixed, immovable reference points
provide precise, reproducible spatial data that can be verified later. Combining this with
photography creates a comprehensive record. Single-photograph documentation lacks
measurement context, written descriptions alone are subjective, and freehand
sketches without measurements lack forensic precision.
Question 3: Rigor mortis typically begins to develop in which sequence throughout
the body?
A. Head to toe (cephalocaudal)
B. Toe to head (caudocephalic)
C. Simultaneously in all muscle groups
D. Randomly based on ambient temperature only

Tasks, Unit Questions and Answers, Death Investigation Procedures,
Forensic Pathology Basics, Scene Investigation, Evidence Handling, and
Competency-Based Assessment Preparation
CORRECT ANSWER: A. Head to toe (cephalocaudal)
RATIONALE:Rigor mortis follows a predictable cephalocaudal progression, beginning in
the smaller muscles of the face and jaw, then progressing to the neck, upper
extremities, trunk, and finally the lower extremities. This pattern assists investigators in
estimating time since death, though environmental factors can modify the timeline.
Question 4: Which manner of death classification is appropriate when a decedent
dies from complications of a self-inflicted gunshot wound with clear evidence of
suicidal intent?
A. Homicide
B. Accident
C. Suicide
D. Undetermined
CORRECT ANSWER: C. Suicide
RATIONALE:Suicide is the manner of death classification used when evidence
demonstrates the decedent intentionally caused their own death. The presence of a
self-inflicted wound with corroborating evidence of intent (note, circumstances, history)
supports this classification. Homicide involves another person, accident lacks intent,
and undetermined is reserved for insufficient evidence.
Question 5: During a death investigation, which document is MOST critical for
establishing the chain of custody for physical evidence?
A. The investigator's personal field notes
B. The evidence log with signatures at each transfer point
C. The medical examiner's autopsy report
D. The law enforcement incident report
CORRECT ANSWER: B. The evidence log with signatures at each transfer point
RATIONALE:A properly maintained evidence log documenting each person who
handled evidence, with dates, times, and signatures at every transfer point, is essential
for establishing an unbroken chain of custody. This documentation is critical for
evidentiary admissibility in legal proceedings. Personal notes, autopsy reports, and
incident reports support the investigation but do not substitute for formal chain-of-
custody documentation.
Question 6: Livor mortis that is fixed and does not blanch with pressure typically
indicates the body has been in position for approximately how long?

Tasks, Unit Questions and Answers, Death Investigation Procedures,
Forensic Pathology Basics, Scene Investigation, Evidence Handling, and
Competency-Based Assessment Preparation
A. 30 minutes to 2 hours
B. 2 to 4 hours
C. 8 to 12 hours
D. 24 to 48 hours
CORRECT ANSWER: C. 8 to 12 hours
RATIONALE:Livor mortis becomes fixed (non-blanching) when blood has fully settled
and hemolyzed within the dependent capillaries, typically occurring 8-12 hours
postmortem. Early livor (30 minutes-4 hours) is unfixed and will blanch or shift with
repositioning. Fixed livor helps estimate time since death and can indicate if a body has
been moved after death.
Question 7: Which of the following findings is MOST suggestive of a defensive
wound pattern?
A. Incised wounds on the anterior neck
B. Abrasions and lacerations on the palms and forearms
C. Patterned bruising on the posterior torso
D. Petechiae in the conjunctivae
CORRECT ANSWER: B. Abrasions and lacerations on the palms and forearms
RATIONALE:Defensive wounds typically occur on the hands, palms, and forearms as a
victim attempts to protect themselves from an assailant wielding a weapon. These
injuries often include incised wounds, abrasions, or lacerations consistent with
grasping or blocking a blade. Neck wounds suggest offensive attack patterns, posterior
bruising may indicate restraint, and petechiae suggest asphyxia.
Question 8: When investigating a suspected drug overdose death, which specimen
is considered the GOLD STANDARD for toxicological analysis?
A. Urine
B. Saliva
C. Peripheral blood (femoral)
D. Vitreous humor
CORRECT ANSWER: C. Peripheral blood (femoral)
RATIONALE:Femoral (peripheral) blood is preferred for toxicological analysis because it
is less susceptible to postmortem redistribution artifacts that can affect central blood
samples. While vitreous humor is valuable for electrolyte and glucose analysis, and

urine detects metabolites, femoral blood provides the most reliable quantification of
parent drugs and alcohol at time of death.
Question 9: Which legal document authorizes a medicolegal death investigator to
take custody of a deceased person under the jurisdiction of the medical examiner
or coroner?
A. Search warrant
B. Subpoena
C. Coroner's or medical examiner's statutory authority
D. Family consent form
CORRECT ANSWER: C. Coroner's or medical examiner's statutory authority
RATIONALE:Medicolegal death investigators operate under statutory authority granted
to the coroner or medical examiner by state or local law, which permits them to take
custody of decedents falling within their jurisdiction without requiring additional
warrants or family consent. This authority is specific to deaths meeting jurisdictional
criteria (sudden, unexpected, violent, suspicious, or unattended).
Question 10: In a death investigation involving an infant, which finding is MOST
consistent with Sudden Infant Death Syndrome (SIDS) after a thorough scene
investigation and autopsy?
A. Ligature marks around the neck
B. Prone sleeping position with no other explanatory findings
C. Multiple rib fractures in various stages of healing
D. Toxicology positive for sedative medications
CORRECT ANSWER: B. Prone sleeping position with no other explanatory findings
RATIONALE:SIDS is a diagnosis of exclusion made after a complete autopsy, death
scene investigation, and review of clinical history reveal no other cause of death. The
prone sleeping position is a recognized risk factor. Ligature marks suggest strangulation,
rib fractures indicate possible abuse, and positive toxicology suggests accidental or
intentional poisoning—all of which would exclude a SIDS classification.
Question 11: Which of the following best describes the difference between cause
of death and manner of death?
A. Cause is the disease or injury; manner is the circumstance (natural, accident, etc.)
B. Cause is the time of death; manner is the location
