Question 1Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

In a medical examiner system, who holds statutory authority to certify the cause and manner of death for a case within the office's jurisdiction?

  1. The funeral director arranging the final disposition
  2. The medical examiner or a designated physician Correct answer.
  3. The attending physician who most recently treated the decedent
  4. The investigating law enforcement officer assigned to the case

Explanation

Certification of cause and manner of death for reportable deaths rests with the medicolegal authority, not with treating clinicians or scene personnel. The medical examiner may delegate to a designated physician within the office, but the statutory responsibility remains with the office.

Question 2Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which statement best captures the structural difference between a coroner system and a medical examiner system?

  1. Coroners are usually elected lay officials, while medical examiners are appointed physicians Correct answer.
  2. Coroners must be forensic pathologists, while medical examiners need not hold a medical degree
  3. Coroner offices handle only criminal cases, while medical examiner offices handle only natural deaths
  4. Coroners may perform autopsies themselves, while medical examiners may only order them

Explanation

The classic distinction is political versus professional: coroners are typically elected and may have no medical training, while medical examiners are appointed physicians, usually forensic pathologists. Both systems investigate the same categories of reportable deaths, and jurisdictional scope is set by statute rather than by the type of case.

Question 3Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A decedent with a gunshot wound to the chest is certified with 'homicide' listed on the death certificate. In this context, 'homicide' describes which element?

  1. The underlying cause of death
  2. The immediate cause of death
  3. The mechanism of death
  4. The manner of death Correct answer.

Explanation

Manner of death classifies how the death came about and uses categories such as natural, accident, suicide, homicide, and undetermined. The cause of death would be the gunshot wound itself, and the mechanism would be the physiologic derangement such as hemorrhage. Homicide as a manner designation is a medicolegal classification and does not by itself establish criminal liability.

Question 4Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

An investigator collects a prescription bottle at a scene. Which action best preserves the chain of custody?

  1. Placing the item in the bag with the decedent's clothing for transport with the body
  2. Handing the item to the responding officer without any written notation
  3. Recording the item, its location, and each transfer with date and time Correct answer.
  4. Photographing the item and leaving it in place for the family to collect

Explanation

Chain of custody requires a documented, unbroken record of who handled an item, when, and where, from seizure through final disposition. Contemporaneous written entries for each transfer make the item defensible in court and reveal any gap.

Question 5Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

At a death scene in a jurisdiction served by a medical examiner, who has authority over the body and over evidence related to the death?

  1. The medical examiner or the investigator representing that office Correct answer.
  2. The decedent's legal next of kin, once they arrive and are identified
  3. The funeral home that holds the county's removal contract for that area
  4. The senior patrol officer who was first to arrive at the scene

Explanation

The medicolegal authority, acting through its investigators, takes jurisdiction over the body and over items bearing on the cause and manner of death. Other responders secure the scene and assist, but they do not displace that authority.

Question 6Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

What does registry certification through the American Board of Medicolegal Death Investigators signify?

  1. A guaranteed appointment to a medical examiner office after training
  2. Statutory authority to pronounce death in all fifty states
  3. Verified knowledge and competence in medicolegal death investigation Correct answer.
  4. A license to perform autopsies independently without physician supervision

Explanation

Registry certification is a credential demonstrating that an investigator has met an established body of knowledge and passed an examination. It is a professional recognition of competence, not a statutory grant of authority, and it varies by level of certification.

Question 7Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

When an investigation requires examination of a body that has already been buried, the lawful basis for disinterment generally comes from:

  1. The written permission of the funeral director who conducted the burial
  2. A court order obtained by the investigating office under statutory authority Correct answer.
  3. The written permission of the cemetery owner, since the grave is on private land
  4. Verbal consent from the majority of the surviving family members

Explanation

Exhumation is a legal procedure that requires authority recognized by statute, typically a court order petitioned for by the medicolegal office or prosecutor. Consent from families or cemeteries may support the petition but does not substitute for the legal authorization.

Question 8Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which approach is most appropriate when making the initial death notification to a family?

  1. Releasing the name to media first so the public can help confirm identity
  2. Providing a provisional cause of death before autopsy to reduce uncertainty
  3. Confirming identity and relationship and giving only verified information Correct answer.
  4. Asking the family to identify the body from a photograph taken at the scene

Explanation

Notification should be made in person by appropriately prepared personnel, after identity and relationship are confirmed. Only information that has been verified is shared, and premature cause-of-death statements are avoided because they often change after autopsy.

Question 9Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

For a death that falls within medical examiner jurisdiction, who completes the medical certification portion of the death certificate?

  1. The attending physician who last saw the patient
  2. The local registrar of vital records
  3. The medical examiner or a physician designee Correct answer.
  4. The funeral director handling disposition

Explanation

When a death is reportable, the medicolegal office assumes responsibility for the medical certification, including cause and manner. The attending physician certifies only those deaths that are properly outside jurisdiction and have an ascertainable natural cause.

Question 10Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

An investigator receives a subpoena duces tecum. What does this instrument compel?

  1. Testimony only, with no documents required to be produced
  2. Immediate arrest of the person served with the subpoena
  3. A search of the investigator's home and vehicle without consent
  4. Production of specified documents or records Correct answer.

Explanation

A subpoena duces tecum commands the recipient to bring specified records or items to a designated proceeding. It is distinct from a subpoena ad testificandum, which compels testimony alone.

Question 11Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which statement most accurately describes release of investigative reports held by a medical examiner office?

  1. Release is governed by state public records law, which often exempts active files and health information Correct answer.
  2. Records are never releasable because an open death investigation is permanently confidential
  3. All investigative records become public immediately upon completion of the report
  4. Only the federal Freedom of Information Act applies to local medical examiner records and makes them fully public

Explanation

Medical examiner offices are typically state or local agencies subject to the public records statutes of their jurisdiction. Those statutes commonly contain exemptions for active investigations, protected health information, and certain autopsy photographs, so release is determined case by case under the applicable law.

Question 12Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A decedent is a registered organ donor and the death falls within medical examiner jurisdiction with no evidence of foul play. What is the appropriate action?

  1. Sign the consent form on the family's behalf so procurement may proceed
  2. Cancel the donation because the death is under investigation
  3. Notify the organ procurement organization promptly while preserving evidence Correct answer.
  4. Delay notification to the procurement organization until the autopsy is finished

Explanation

Federal and state frameworks require timely referral of potential donors to the organ procurement organization, and the medicolegal authority may permit recovery while limiting procedures that would compromise evidence. Prompt notification preserves the option for donation without sacrificing the investigation.

Question 13Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

May a medical examiner disclose decedent health information to law enforcement investigating that death under HIPAA?

  1. Yes; disclosure for identification or investigation of a death is permitted Correct answer.
  2. Only if the requesting officer is a member of the decedent's family
  3. No; HIPAA protects a decedent's records for fifty years after death
  4. Only with a signed authorization the decedent gave before death

Explanation

HIPAA permits covered entities, including medical examiner and coroner offices, to disclose protected health information to law enforcement for purposes such as identification of a decedent or investigation of a death. Authorization is not required when the disclosure fits an enumerated permission.

Question 14Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

An investigator arrives at a scene where a body is found in a closed garage with a vehicle engine running. What is the appropriate first priority?

  1. Interviewing neighbors about the decedent's recent habits and behavior
  2. Ensuring scene safety and requesting a hazmat assessment before entry Correct answer.
  3. Beginning the external examination to estimate a preliminary time of death
  4. Photographing the decedent's position before anything is moved

Explanation

Scene safety precedes all investigative functions; carbon monoxide and other hazards can injure responders and contaminate documentation. Entry is delayed until the atmosphere is assessed and the scene is made safe, after which photography and examination proceed.

Question 15Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A death occurs on a military installation located within a state. Which statement best describes medicolegal jurisdiction?

  1. The installation's commanding officer is the sole medicolegal authority for the death
  2. Both federal and state or local authority may apply, coordinated under statute Correct answer.
  3. The local coroner automatically loses all jurisdiction to the Federal Bureau of Investigation
  4. State medical examiner jurisdiction never applies to a death that occurs on federal property of any kind

Explanation

Deaths on federal enclaves can implicate both federal investigative authority and state or local medicolegal authority, depending on the governing statutes and agreements. Coordination with military criminal investigative organizations and the local medicolegal office is standard practice to avoid gaps in the investigation.

Question 16Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

An inmate dies while in custody at a county jail. Which principle best guides the death investigation?

  1. The jail's medical contractor certifies the death without any outside review
  2. It requires independent review, outside notification, and autopsy consideration Correct answer.
  3. The investigation may be handled informally by the sheriff's own detention staff
  4. The death is presumed natural unless a weapon is recovered at the scene

Explanation

Custodial deaths are reportable and demand an independent investigation that avoids any appearance of institutional self-review. Common practice includes notification of an outside agency, scene documentation, review of custody records and video, and autopsy with toxicology.

Question 17Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which statement best reflects the accepted standard for death investigation documentation?

  1. Observations are recorded contemporaneously in objective terms Correct answer.
  2. Notes may be discarded once the formal typed report has been approved
  3. Only photographs are required, and written field notes are optional
  4. Reports should include the investigator's assessment of the decedent's character

Explanation

Field notes should be written as events unfold, using factual language that separates what was observed from what was inferred. Notes are retained as discoverable material, and character commentary is irrelevant to the medicolegal findings.

Question 18Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

An investigator testifies only about what they personally observed and did at the death scene. In that testimony the investigator is functioning as:

  1. An expert witness
  2. A lay or fact witness Correct answer.
  3. A guardian ad litem
  4. A court-appointed special master

Explanation

A witness who recounts personal observations and actions gives fact testimony, and the investigator may testify in that capacity as well as offer expert opinions if qualified. The distinction matters because expert opinion testimony is subject to qualification and disclosure requirements.

Question 19Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

In a mass fatality incident, which framework most commonly organizes the death investigation response?

  1. Each responding agency independently recovers, numbers, and stores the remains it finds
  2. The investigative office works alone and declines assistance from other agencies
  3. The coroner transfers all identification authority to the funeral industry
  4. The Incident Command System, coordinated by the medicolegal authority Correct answer.

Explanation

Mass fatality response is organized through the Incident Command System, with the medicolegal authority leading morgue operations, remains tracking, and victim identification. Unified command prevents duplicate numbering, lost remains, and inconsistent identification standards.

Question 20Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which is considered a primary, scientifically reliable method of identifying a decedent?

  1. Tattoos and scars described by family
  2. Visual recognition by a relative
  3. Personal effects found with the body
  4. Scientific comparison such as fingerprints, dental records, or DNA Correct answer.

Explanation

Primary identification relies on objective comparison of antemortem and postmortem data such as fingerprints, dental records, DNA, or radiographs. Visual and circumstantial methods are secondary and may be used only as supporting evidence.

Question 21Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A body is recovered from a river that forms the boundary between two states. Jurisdiction generally depends on:

  1. The state where the decedent maintained legal residence at the time of death
  2. The state in which the decedent was first reported missing to authorities
  3. The state where the family intends to hold the funeral and burial
  4. The location of recovery under state statutes, often set by interagency agreement Correct answer.

Explanation

Jurisdiction over boundary-water deaths turns on where the body was recovered and the reach of each state's statutes, which may be clarified by interstate agreements. Residence, missing-person reports, and burial plans do not determine which office investigates.

Question 22Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A family objects on religious grounds to an autopsy in a case within the medical examiner's statutory jurisdiction. Which statement best describes the governing rule?

  1. Family objection always overrides the medical examiner's statutory authority
  2. Statutory authority generally allows the examination to proceed Correct answer.
  3. An autopsy is prohibited whenever any family member objects in writing
  4. The objection must be filed with the state registrar before the autopsy may begin

Explanation

When a death is reportable and within jurisdiction, the medicolegal authority may proceed with examination despite family objection. Some statutes require reasonable accommodation, consultation, or a court hearing, but the objection alone does not eliminate jurisdictional authority.

Question 23Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

A funeral home offers an investigator gifts in exchange for directing families to its services. Which principle governs the investigator's response?

  1. Private arrangements between professionals are outside the scope of standards
  2. Accepting gifts is acceptable as long as it is disclosed to a supervisor
  3. Referrals are permitted because funeral homes are licensed and regulated
  4. The investigator must avoid conflicts of interest Correct answer.

Explanation

Public officials and investigators must not use their position for private gain or allow financial interests to influence professional judgment. Accepting referral payments or gifts undermines impartiality and typically violates ethics rules and office policy.

Question 24Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Which statement about estimating time of death is most accurate?

  1. Postmortem interval estimates are approximate, not exact Correct answer.
  2. Rigor mortis alone reliably fixes the time of death to within minutes
  3. Livor mortis alone provides an exact postmortem interval in most cases
  4. The death certificate must state an exact time of death in every case

Explanation

Postmortem changes are influenced by temperature, body habitus, clothing, and other variables, so interval estimates are ranges supported by multiple findings. Investigators combine scene information, witness statements, and physical findings rather than relying on a single sign.

Question 25Medicolegal Death Investigation Principles, Jurisdiction, and the Role of the Investigator

Under most state statutes, which death must be reported to the medicolegal authority?

  1. A death within 24 hours of hospital admission with no reliable certifiable cause Correct answer.
  2. Any death for which the family requests that an autopsy be performed
  3. Any death of a person over 65 occurring in a nursing home
  4. Any death following a long diagnosed terminal illness under hospice care

Explanation

Reportable death categories generally include deaths unattended by a physician, deaths occurring shortly after admission without an established cause, and deaths from violence, poisoning, or unexplained circumstances. Age, hospice status, and family preference are not by themselves the statutory triggers.

Question 26Initial Response, Notification, and Scene Assessment

Upon arriving at a residence where a death has been reported, the investigator's first priority is to:

  1. ensure the safety of themselves and others at the scene Correct answer.
  2. photograph the decedent's position before it is altered
  3. measure the decedent's liver temperature
  4. interview the family about the decedent's medical history

Explanation

Scene safety always precedes evidence work. The investigator must identify hazards such as gas, weapons, hostile persons, or structural dangers before approaching the body. Documentation and interviews follow only once the scene is safe.

Question 27Initial Response, Notification, and Scene Assessment

Which death ordinarily falls within medicolegal (medical examiner or coroner) jurisdiction?

  1. A hospice patient whose attending physician has been managing end-of-life care
  2. A person found dead at home with no attending physician and no recent medical care Correct answer.
  3. A nursing home resident with a documented terminal illness and physician in attendance
  4. A hospitalized patient who dies after two weeks of treatment for heart failure

Explanation

Medicolegal jurisdiction generally covers deaths that are unattended, unexpected, violent, suspicious, or not certifiable by a treating physician. A person found dead with no physician and no recent care fits this category. Deaths under active physician care with a documented terminal illness are usually certified by the attending physician.

Question 28Initial Response, Notification, and Scene Assessment

When delivering a death notification to the next of kin, the investigator should:

  1. ask the family to come to the scene to identify the body before telling them
  2. soften the news by saying the person 'is no longer with us'
  3. use direct language such as 'I am sorry to tell you that your son has died' Correct answer.
  4. provide the preliminary cause of death in detail

Explanation

Death notifications should be clear and direct so the message is not misunderstood. Euphemisms can cause confusion, and cause-of-death details should be withheld until the investigation supports them. The family should be told before being asked to view or identify the body.

Question 29Initial Response, Notification, and Scene Assessment

The decedent's prescription medications found at the scene are most useful to the investigator because they:

  1. replace the need for a medical history interview
  2. establish the legal cause of death
  3. prove who was present at the time of death
  4. provide a picture of the decedent's recent medical conditions and treatment Correct answer.

Explanation

Medication containers document diagnoses, prescribing physicians, and recent treatment, which help build the medical history. They are circumstantial information and do not by themselves establish cause of death or the presence of other persons. A history interview remains necessary.

Question 30Initial Response, Notification, and Scene Assessment

Before entering a scene with a decomposed body and visible body fluids, the investigator should at minimum wear:

  1. standard street clothing with shoe covers
  2. a surgical mask only
  3. gloves, eye protection, and a fluid-resistant gown or suit Correct answer.
  4. a reflective vest and hard hat

Explanation

Universal precautions require barriers against contact with blood and body fluids. Gloves, eye protection, and fluid-resistant outerwear protect against splash and contact exposure. A mask alone or street clothing does not provide adequate protection.

Question 31Initial Response, Notification, and Scene Assessment

Lividity that remains pale when the skin is pressed and does not shift when the body is turned indicates:

  1. lividity is fixed and the postmortem interval is likely several hours or more Correct answer.
  2. the decedent died of carbon monoxide poisoning
  3. the body was kept in a refrigerator
  4. the body has been dead less than one hour

Explanation

Lividity begins as a blanchable pattern that shifts with repositioning and later becomes fixed as blood settles and vessel tone is lost. Fixation generally indicates a postmortem interval of several hours or more. It is not a marker of a specific cause of death.

Question 32Initial Response, Notification, and Scene Assessment

Cherry-red lividity at a scene where a generator was running in an enclosed garage most strongly suggests:

  1. cyanide poisoning
  2. carbon monoxide poisoning Correct answer.
  3. acute alcohol intoxication
  4. hypothermia

Explanation

Carbon monoxide binds hemoglobin and can produce a characteristic cherry-red or pink coloration of the skin and lividity. The enclosed space with a fuel-burning generator is a classic exposure setting. Other causes do not typically produce this combination.

Question 33Initial Response, Notification, and Scene Assessment

At a suspected opioid overdose scene where loose powder is visible, the investigator's primary safety action is to:

  1. taste a small amount to confirm the substance
  2. avoid handling or disturbing the powder and request specialized assistance Correct answer.
  3. open windows and continue the examination without respiratory protection
  4. sweep the powder up before photographing the scene

Explanation

Potent synthetic opioids can be hazardous through inhalation or contact, so the investigator should not disturb visible powder. Specialized personnel should handle and collect the substance. The scene is documented from a safe distance until the hazard is controlled.

Question 34Initial Response, Notification, and Scene Assessment

When taking custody of the decedent's personal property at the scene, the investigator should:

  1. place all items in one unlabeled bag
  2. itemize each item in writing and document the transfer with signatures Correct answer.
  3. leave valuables on the body for the funeral home
  4. give the items to the first relative who arrives

Explanation

Personal property must be inventoried and its custody tracked so items are not lost or misidentified. Each transfer should be documented with signatures as part of the chain of custody. Valuables should not be left unsecured or handed out informally.

Question 35Initial Response, Notification, and Scene Assessment

The body should not be released from the scene to a funeral home until:

  1. the death certificate has been signed
  2. the family has selected a funeral home
  3. the police have left the scene
  4. the investigator has completed scene documentation and the medical examiner or coroner has authorized release Correct answer.

Explanation

Release requires that the scene work be complete enough to preserve evidence and that the medicolegal authority approve removal. The death certificate is often completed later. Family preference and police departure do not control release.

Question 36Initial Response, Notification, and Scene Assessment

The most important information to obtain during the initial death call is:

  1. the decedent's insurance information
  2. the name and exact location of the decedent and the caller's contact information Correct answer.
  3. the decedent's religious affiliation
  4. the funeral home the family prefers

Explanation

The initial call establishes the response: who is reported dead, exactly where they are, and how to reach the caller. Other details can be gathered later. Without accurate location and contact information, the investigator cannot respond or follow up.

Question 37Initial Response, Notification, and Scene Assessment

When organ or tissue donation is being considered for a decedent under medicolegal jurisdiction, the investigator should:

  1. tell the family donation is not possible in any medicolegal case
  2. authorize donation independently to expedite the process
  3. inform the donation coordinator and obtain medical examiner or coroner approval before recovery Correct answer.
  4. permit recovery before scene documentation to preserve organ viability

Explanation

The medical examiner or coroner retains authority over the body in medicolegal cases, and donation may still proceed with that authority's approval. The investigator coordinates with the donation organization rather than granting approval personally. Scene documentation must not be sacrificed.

Question 38Initial Response, Notification, and Scene Assessment

The medical examiner declines jurisdiction over a death at a private residence. The investigator should next:

  1. document the decision and the basis, and ensure the attending physician will certify the death so the family may proceed with a funeral home Correct answer.
  2. leave without documenting anything
  3. send the body to the morgue anyway
  4. sign the death certificate personally

Explanation

A declination should be recorded with its rationale, and the case must be routed to a physician who can certify the death. This allows the family to proceed with disposition. The investigator does not sign the death certificate or transport a body the office has declined.

Question 39Initial Response, Notification, and Scene Assessment

The preferred way to begin the scene assessment is to:

  1. start by bagging items near the body
  2. conduct a systematic walk-through, noting conditions before anything is touched Correct answer.
  3. interview all neighbors before entering
  4. move the body to a better lit area

Explanation

A systematic walk-through establishes the layout, hazards, and evidence locations before anything is altered. Observations made at this stage guide photography and collection. Moving or bagging items before this survey risks losing information.

Question 40Initial Response, Notification, and Scene Assessment

Scene photographs should include:

  1. close-ups only of the wounds
  2. only photographs taken by police
  3. images edited to remove clutter
  4. overall, midrange, and close-up views with a scale where appropriate Correct answer.

Explanation

A complete photographic record moves from the general to the specific: overall views orient the viewer, midrange views show relationships, and close-ups document detail. A scale allows measurement and interpretation. Editing images undermines their evidentiary value.

Question 41Initial Response, Notification, and Scene Assessment

A decedent is found floating in a canal. The investigator should first:

  1. drain the canal to search for evidence
  2. ask bystanders to help lift the body
  3. pull the body to shore to check for identification
  4. secure the scene, photograph the body as found, and coordinate recovery without disturbing it Correct answer.

Explanation

A body in water is evidence in the position found, and movement can alter that evidence and the scene. The investigator secures the area and documents conditions before a coordinated recovery. Bystanders should not be used to move the body.

Question 42Initial Response, Notification, and Scene Assessment

The best approach to interviewing the person who discovered the body is to:

  1. interview them together with other family members
  2. delay the interview until the autopsy
  3. interview them separately and record their account in their own words Correct answer.
  4. ask leading questions to speed the process

Explanation

Witnesses should be interviewed individually so their accounts are not shaped by others. Recording the statement in the witness's own words preserves accuracy and detail. Leading questions and delay reduce reliability.

Question 43Initial Response, Notification, and Scene Assessment

At the scene, a wallet containing a driver's license is found near the decedent. The investigator should treat this finding as:

  1. sufficient only if the photograph is recent
  2. irrelevant to identification
  3. conclusive proof of identity
  4. presumptive identification that must be confirmed by other means Correct answer.

Explanation

Documents near a body suggest identity but do not prove it, since wallets can be misplaced or deliberately placed. Identification should be confirmed through fingerprints, dental comparison, family confirmation, or other reliable means. The investigator records the finding and continues verification.

Question 44Initial Response, Notification, and Scene Assessment

When a decedent cannot be identified at the scene, the investigator should:

  1. wait for a family member to call the office
  2. document distinguishing features and pursue identification through fingerprints, dental records, or DNA as appropriate Correct answer.
  3. list the decedent as a John or Jane Doe on the death certificate immediately
  4. release the body as unidentified without further action

Explanation

Unidentified decedents require a documented description of physical features and active identification efforts such as fingerprints, dental comparison, or DNA. Passive waiting is not an investigation. A placeholder name may be used temporarily, but it does not replace identification efforts.

Question 45Initial Response, Notification, and Scene Assessment

If family members at the scene become threatening, the investigator should:

  1. physically restrain the family members
  2. argue with the family about jurisdiction
  3. withdraw to a safe location and ask law enforcement to assist Correct answer.
  4. continue the examination to avoid delay

Explanation

Personal safety takes priority, and the investigator has no authority to physically control family members. Withdrawing and requesting law enforcement assistance allows the investigation to continue safely. Confrontation worsens the situation.

Question 46Initial Response, Notification, and Scene Assessment

A decedent is found with a firearm nearby and a note on the table. The investigator should:

  1. treat the death as a homicide investigation until scene and autopsy evidence support another manner, and leave the weapon for law enforcement to collect Correct answer.
  2. unload and bag the firearm personally
  3. conclude suicide immediately and release the scene
  4. remove the note and give it to the family

Explanation

A note and firearm suggest suicide but do not by themselves establish the manner of death. The investigation proceeds objectively until scene, toxicology, and autopsy findings are consistent. The weapon and note are evidence to be documented and collected through proper channels.

Question 47Initial Response, Notification, and Scene Assessment

Which finding most strongly suggests the body was moved after death?

  1. lividity fixed in a pattern that does not match the position in which the body was found Correct answer.
  2. rigor mortis present in the jaw
  3. cloudiness of the corneas
  4. pale skin

Explanation

Fixed lividity records the position in which blood settled; a pattern inconsistent with the position of the body indicates it was moved after fixation. Rigor and corneal changes estimate time but do not themselves indicate movement. Pale skin is nonspecific.

Question 48Initial Response, Notification, and Scene Assessment

The investigator should generally avoid stating a cause of death to the family at the scene because:

  1. families are not entitled to any information
  2. only police may speak with families
  3. the cause is determined after the investigation and autopsy, and premature statements may be inaccurate Correct answer.
  4. the death certificate is already complete

Explanation

Cause of death is determined after scene findings, history, and autopsy results are integrated. Statements made at the scene may be wrong and are difficult to retract. The investigator can explain the process without speculating.

Question 49Initial Response, Notification, and Scene Assessment

In the death of an infant at home, the investigator should:

  1. assess and photograph the sleep environment and interview caregivers separately Correct answer.
  2. limit the investigation to the body
  3. allow the family to rearrange the scene
  4. assume sudden infant death syndrome and close the case

Explanation

Infant deaths require a thorough scene assessment because the sleep environment and caregiver accounts are central to distinguishing natural, accidental, and inflicted causes. Caregivers should be interviewed separately to preserve independent accounts. No manner should be assumed at the scene.

Question 50Initial Response, Notification, and Scene Assessment

At a scene with a suspected sharp-force death, the knife should be:

  1. picked up and placed in the investigator's bag
  2. left in place, photographed, and collected by law enforcement or evidence personnel following chain-of-custody procedures Correct answer.
  3. returned to the kitchen drawer
  4. handed to the family

Explanation

The weapon is evidence and should be documented in place before collection by the appropriate evidence personnel. Chain of custody must be maintained from collection onward. Moving, storing, or releasing the item compromises the case.
