Definition / general
- Completing a forensic autopsy report is an art in itself
- Everything, including the decedent's demographics, circumstances of death, external examination, clothing / personal effects, medical intervention, radiographic imaging, evidence of injury, internal examination, microscopic examination, specific organ system pathology consultation, final autopsy diagnosis, and opinion sections should complement one another in a cohesive manner
- No two autopsy reports are the same; keep an open mind for each case
- If using a template, take care to make the appropriate changes to suit each case
- Cause of death (COD) is usually straightforward, but the manner of death (MOD) and mechanism of death tend to be more challenging
Differences from nonforensic autopsies
- Forensic autopsies emphasize identification of deceased, time of death, proper handling of evidence, recognition of injuries and pathological conditions that may be relevant to the court case
- For homicide court cases, an autopsy report is only one piece of the pie
- Law enforcement investigators, attorneys, forensic science experts (e.g., trace evidence, fingerprints) and other expert witnesses will fill in the rest
- Depending on the jurisdiction, the cover page of a forensic autopsy report includes: demographics of the decedent, circumstances of death, identification, cause of death and manner of death
Undetermined cases
- Having an autopsy report with an undetermined cause and undetermined manner of death (undetermined / undetermined) is very rare; only if all evidence at autopsy is inconclusive
- Frequency of undetermined cases: not more than 1% - 2% of all autopsy cases done by a forensic pathologist in one year
High profile cases
- Conduct "VIP" / high profile cases as if you would routinely perform like any other case to avoid unnecessary mistakes
- Depending on the case, high profile or difficult autopsies should be checked by another forensic pathologist for accuracy
- FP should be board certified in at least anatomic and forensic pathology for competency measures
Demographics of the decedent
- Decedent: person who died (a legal term)
- Include full name, autopsy number, social security number, age, date of birth, date of death, date of autopsy performed, place of death and date of autopsy report completed
Circumstances of death
- Events that occurred prior to the person's death, such as when last seen alive, prior hospitalizations, and pertinent positive / negative evidence to support COD / MOD
Identification
- Antemortem / postmortem fingerprint, dental, radiographs or DNA comparison is objective evidence and is added to evidence from pictures, driver license or other unique identifiers (e.g., tattoos or amputations)
Cause of death
- Drowning, gunshot wound to the chest, acute myocardial infarction, multidrug toxicity (overdose), undetermined, etc.
Manner of death
- Accident, homicide, natural, suicide or undetermined
Preliminary investigation
- Circumstances of death need to be reported by the forensic pathologist (FP) based on information provided by law enforcement personnel who are familiar with the death scene
- Depending on the case, the FP can obtain crucial information at the death scene or by a phone call to law enforcement investigators
- Asking specific questions related to the case will help provide clues to Cause / Manner of Death (COD / MOD)
- Specific questions related to the decedent's past (medical history, recent surgeries, state of mental health, drug / alcohol abuse, etc.) may reduce the need to perform a complete autopsy when only toxicology analysis is required to determine COD / MOD
External examination
- Overall: state body weight, height, age, body temperature, rigor and lividity
- Head / neck: describe hair color, facial hair, eye color, oral cavity, ear canals, nose, lips and teeth
- Torso: describe chest, abdomen, back, anus and genitalia
- Extremities: describe upper / lower limbs and fingernails / toenails
- Miscellaneous: describe tattoos, ID tags, medical / surgical intervention, etc.
- Clothing: describe any defects to support cause of death (COD)
- Body surface: state anything to suggest evidence of cause of death, such as gunshot wounds, blunt trauma, sharp force injury, illicit drug residue, anasarca, obesity, emaciation, sexual assault
Internal examination
- General:
- Organs need to be weighed
- All lesions need to be measured in 3 dimensions, if possible
- Evidence of Injury does not need to be repeated in each organ system; a statement such as "see 'evidence of injury' above" will suffice
- Natural causes of death are usually found in this section of the autopsy report: body cavities, head / CNS / neck, cardiovascular system, respiratory system, hepatobiliary system, gastrointestinal system, genitourinary system, lymphorecticular system, endocrine system, and musculoskeletal system
- Body cavities: state any abnormal pericardial, thoracic or abdominal fluid acumination
- Head / CNS / neck: look for lesions involving the scalp, calvarium, dura mater, falx cerebri, leptomeninges, cerebral hemispheres, gyri / sulci, cut sections of brain, brain stem, cranial nerves, major blood vessels, CSF, cerebellum, atlanto-occipital joint, thyroid cartilage, hyoid bone, larynx, tongue, etc.
- Cardiovascular system: epicardial surface, coronary arteries (distribution, patency versus occlusion, and wall thickness), myocardium (LV / RV / septum) thickness, valves, endocardium, aorta, renal vessels, mesenteric vessels, etc.
- Respiratory system: upper airway, mucosa, pleural surfaces, pulmonary parenchyma, vasculature, etc.
- Hepatobiliary system: hepatic capsule, liver parenchyma / vasculature, gall bladder serosa / mucosa, etc.
- Gastrointestinal system: esophagus, gastric mucosa, small bowel, colon, appendix, pancreas, etc.
- Genitourinary system: renal capsule(s), cortical surface(s), cortical / medullary parenchyma, bladder, male organs (testes, prostate), female organs (ovaries, uterus), etc.
- Lymphorecticular system: splenic capsule, splenic parenchyma, regional lymph nodes, etc.
- Endocrine system: pituitary gland, thyroid gland, adrenal glands, etc.
- Musculoskeletal system: muscle and bone structures
Evidence of injury (examples)
- This section usually contains both external and internal descriptions of injury
- Gunshot wounds (GSW): list each GSW trajectory separately, determine how many entry (penetrating) / exit (perforation) wounds, range of fire, soot / stippling, trajectory, recovery of projectile(s), state in proper order of anatomic landmarks injured by each GSW, hemorrhage, etc.
- Blunt force injuries from motor vehicle accident (MVA): trace evidence collected on body (e.g., paint chips or glass), pattern contusions / abrasions, fractures, lacerations, avulsions, hemorrhage, etc.
- Stab wounds: cuts, incisions, defense wounds, determine the knife's sharp verses blunt end in each skin wound, depth of wound, organs affected, hemorrhage, etc.
- Additional injuries: minor lesions that are attributed by the mechanism or cause of death
Microscopic examination
- Useful for documenting natural disease or gross lesions histologically (e.g., gunpowder residue)
- Describe what is seen microscopically; do not state diagnosis in this section
Additional procedures
- This section may include neuropathology or cardiovascular consultation reports, toxicology reports, autopsy attendance roster, etc.
