Post-Mortem Findings on the Face and Neck in Complete Typical Hanging

Context note - "Complete typical hanging": In complete hanging, the entire body weight acts as the constricting force (feet off the ground). In typical hanging, the knot is positioned over the occiput (back of the neck), which places maximum pressure on the front and sides of the neck, directly over the carotid vessels. These two features together produce the classic, well-defined pattern described below.

A. External Findings on the Face

1. Facial Pallor (Characteristic Feature)

• Correlation with the case: If the case shows a pale, drained face, it supports complete suspension where all arterial supply to the head was occluded.

2. Eyes

• The eyeballs appear prominent and protrude due to congestion (more pronounced in partial hanging but may be seen in complete hanging as well).
• The eyes may be closed or partially open; pupils are usually dilated.
• The conjunctivae are congested; petechial hemorrhages in the conjunctivae are found in ~25% of cases, though they are far more common in incomplete suspension.
• "Le facie sympathique": If the ligature knot compresses the cervical sympathetic chain, the ipsilateral eye may remain open with a dilated pupil - a sign indicating antemortem hanging.

3. Tongue

• It is swollen, turgid, and blue at the base.
• The noose lifts the glossopharyngeal skeleton, causing protrusion of the tongue between the lips and teeth.
• The protruding portion dries out, becoming dark brown or black in colour, due to desiccation (Figure 8.21, DiMaio).
• In complete typical hanging, the tongue may be clamped between the teeth or lips.

4. Lips and Oral Mucosa

• The lips and oral mucous membranes are cyanosed/blue due to asphyxial congestion.
• Slight bloody froth may occasionally be seen at the mouth and nostrils from rupture of engorged vessels in congested lungs - this should not be mistaken for evidence of assault.

5. Salivary Staining (Important Antemortem Sign)

• Saliva dribbles from the angle of the mouth on the side opposite to the knot - a dried rivulet running down the chest is a classic finding.
• This results from stimulation of the salivary glands and pterygopalatine ganglion by the ligature, as well as congestive hypoxia.
• Medicolegal importance: Salivary staining is an important indicator of antemortem hanging - it cannot be reproduced postmortem. Absence does not exclude hanging.

6. Head Position

• The neck is stretched and elongated due to the upward pull of the ligature.
• The head is tilted/inclined to the side opposite the knot, due to gravitational forces.

7. Petechiae

• In complete typical hanging, petechial hemorrhages of the face and conjunctivae are relatively uncommon or absent because both arteries and veins are fully occluded - there is no excess pressure to rupture capillaries in the head.
• Petechiae are characteristic of partial/incomplete suspension where venous return is blocked but vertebral arterial supply continues.

B. The Ligature Mark (Central Finding on the Neck)

Position and Course

• Located above the level of the thyroid cartilage, between the larynx and chin.
• Does not run horizontally around the neck - instead it runs obliquely upward, directed along the line of the mandible toward the mastoid processes behind the ears (Figure 8.17, DiMaio).
• It does not completely encircle the neck - it fades out and is absent or least prominent at the back, where the two limbs of the noose converge at the knot.
• In typical hanging (knot occipital), the front and sides of the neck show the most prominent and deepest mark, while the nape may show little or no mark due to firm musculature and scalp hair.

Shape

• Typically inverted V-shaped (or inverted U-shaped), with the apex of the V directed toward the knot (occiput in typical hanging).
• Impression of the knot may be found as a separate abrasion/indentation at the site.

Appearance of the Groove

• Fresh mark: appears pale, poorly defined.
• After several hours of drying: becomes yellowish-brown, dry, hard, and parchment-like - a leathery groove or furrow.
• The deepest portion of the mark is opposite the point of suspension (i.e., anteriorly in typical hanging).
• Along the edges: a thin line of congestion or ecchymosis may be seen above and below the groove at the deepest point.
• Abrasions with hemorrhage in the groove are strongly suggestive of antemortem hanging.
• Fibres from the ligature may be found adhering to the skin (useful for ligature material identification).

Width and Clarity - Correlation with Ligature Material

• Thin, hard ligature (wire, rope, cord): narrow, deep, distinct groove with mirror-image impression of the material's texture (e.g., twist pattern of rope reproduced on skin).
• Broad, soft ligature (dupatta, sari strip, towel): wide, shallow, ill-defined furrow.
• Fabric pulled tight: only the raised ridges contact the skin, producing a narrower mark than expected.
• A belt leaves two parallel furrows from its upper and lower edges.

Other Features

• A double furrow may be produced by: (a) a double loop, or (b) slipping of the ligature causing two impressions.
• If a knot is under the chin: an abrasion or indentation beneath the chin marks its site.
• Scratch abrasions above and below the ligature may be present in a minority of cases, made by the victim's fingernails trying to loosen the noose during the agonal period.
• Ligature marks resist putrefaction because the compressed vessels restrict access by putrefying bacteria - they can remain identifiable even in decomposed bodies.
• The mark may disappear if the ligature is removed soon after death and the body is observed before drying; it may also be reproduced if the body is suspended within 2 hours of death.

C. Internal Neck Findings (Dissection)

Technique

Findings

• Fractures of the hyoid and thyroid cartilage are accepted as antemortem when there is blood at the fracture site (indicating vital reaction).
• Absence of internal injuries does not exclude antemortem hanging.

Hanging: Definition, Classification, and Post-Mortem Features by Type

I. Definition

"Hanging is always suicidal in nature, unless the contrary is proved beyond reasonable doubt." - The Essentials of FMT, 36th Ed.

II. Classification of Hanging

III. Classification by Degree of Suspension

A. COMPLETE HANGING

Post-Mortem Features of Complete Hanging

• Face is PALE (hallmark feature) - due to complete occlusion of both carotids and vertebral arteries; no blood pools in the head
• Petechial haemorrhages are ABSENT or minimal in the face and conjunctivae - because there is no residual arterial pressure to rupture capillaries in the head
• Eyeballs may be slightly prominent; pupils dilated
• Tongue - protruding, dark brown to black tip (drying), swollen base
• Lips and oral mucosa cyanosed
• Saliva dribbling from the angle of the mouth (side opposite the knot)
• Le facie sympathique may be present if knot compresses the cervical sympathetic

• Neck stretched and elongated; head tilted away from the knot
• Ligature mark: Oblique, running upward toward knot; incomplete (absent/faint at the nape); deep and well-defined anteriorly; parchment-like yellow-brown colour; deepest portion opposite the knot

• Absent on the face (blood drained away)
• Circumferential on the dependent forearms, hands, and lower legs
• Tardieu spots (petechial hemorrhages from hydrostatic vessel rupture) may develop in the lower limbs after several hours of suspension

• Tissues under the groove are dry, white, and glistening (no blood due to compression)
• Strap muscle haemorrhages in ~17-25% of cases
• No injuries in >50% of cases (the low forces needed mean the neck can be compressed fatally without structural damage)
• Hyoid bone fracture in ~15-20% (rare below age 40; more common at the greater horn)
• Thyroid cartilage fracture in ~40-45% (superior horns most commonly)
• Carotid artery intimal tears (5-10%) - antemortem indicator
• Cervical spine fracture: extremely rare in non-judicial hanging

B. PARTIAL (INCOMPLETE) HANGING

• Partial standing (toes or feet just touching the ground)
• Sitting (body seated with neck in noose)
• Reclining / kneeling (lying prone with chest off the ground)
• Hanging from a bedpost, doorknob, or low fixture

• Venous return from the head is blocked
• But the vertebral arteries continue to supply blood to the head
• This creates a net increase in intracranial pressure

Post-Mortem Features of Partial Hanging

• Face is CONGESTED, swollen, and cyanosed - dusky purple/plum colour (due to venous obstruction with continued vertebral arterial supply)
• Petechial haemorrhages are COMMON and prominent - on the face, eyelids, conjunctivae, and skin of the neck above the ligature
• The congested face may show periorbital oedema and facial puffiness; swelling often disappears when the body is cut down
• Eyes - prominent, firmly protruding, conjunctival haemorrhages
• Tongue - deeply cyanosed and protruding
• Decomposition sets in earlier in partial hanging due to the congested, blood-filled head

• Ligature mark is less prominent, shallower, or even absent - because the constricting force is low
• Mark may be found at a lower level on the neck (below the thyroid cartilage) compared to complete hanging
• The oblique, upward, inverted-V pattern is preserved if the knot is posterior, but the mark may be faint or indistinct
• With soft materials (towel, dupatta), no mark may be visible at all

• Present on the face and head (above the ligature)
• Also in the dependent lower limbs
• Tardieu spots more prominent in the lower limbs

IV. Classification by Position of the Knot

C. TYPICAL HANGING (Knot at the Occiput)

Post-Mortem Features of Typical Hanging

• Runs obliquely upward from the front of the neck toward the mastoid processes behind each ear
• Directed along the line of the mandible
• Inverted V shape with the apex of the V pointing toward the occiput
• Mark is present on the front and both sides of the neck
• Absent or faintest at the nape (where the two limbs of the ligature converge at the knot and the firm neck muscles/hair intervene)
• Deepest and most prominent anteriorly (opposite to the knot)
• Level: Above the thyroid cartilage (in ~80% of cases; at the level in 15%; below in only 5%)

• Pale (in complete + typical hanging) - the combined occlusion of all cervical vessels including vertebrals
• Asphyxial signs are minimal
• Saliva dribbles from the angle of the mouth on the side opposite the knot (from the ligature compressing the ipsilateral salivary gland)

D. ATYPICAL HANGING (Knot NOT at the Occiput)

• Knot on one side (most common variant): The ligature mark is asymmetric. The mark is deepest on the side opposite the knot and is more oblique. The head tilts toward the side of the knot.
• Knot under the chin (anterior): The ligature runs horizontally around the neck; the mark may completely encircle the neck horizontally (resembling a ligature strangulation mark). This is the most important variant forensically because it can cause diagnostic confusion.

Post-Mortem Features of Atypical Hanging

• Knot on one side: Oblique course, but asymmetric - mark on the opposite side is deepest and best defined; site of knot shows an indentation or abrasion. Head inclined toward the knot. Conjunctival petechiae may be unilateral (on the side opposite the knot).
• Knot anteriorly (under chin): Mark runs more horizontally and may completely encircle the neck - this pattern mimics ligature strangulation. Differential diagnosis rests on: direction of mark (oblique = hanging; horizontal = strangulation), level of mark (hanging above thyroid cartilage; strangulation below thyroid), and scene findings.

• When the knot is in front, venous drainage may be predominantly blocked while arterial supply via vertebrals is maintained - producing more congestion and petechiae than typical hanging
• Conjunctival haemorrhages may be one-sided when the knot is over one ear

V. Classification by Mode/Circumstance

E. SUICIDAL HANGING

• Any available ligature material used
• Point of suspension: ceiling fan, roof beam, window bars, door, tree
• Simple slip-knot (running noose) most common
• Room often bolted from inside; suicide note may be present
• Usually no other injuries; occasionally self-tied hands to prevent change of mind
• PM features as above (complete/typical combination most common)

F. ACCIDENTAL HANGING

• Most commonly in children caught in cribs, furniture, clothing
• In adults: autoerotic asphyxia (sexual hanging) - elaborate restraints, padded noose, evidence of sexual activity
• In autoerotic cases, soft padded noose may leave faint marks; position may be unusual

G. HOMICIDAL HANGING (Extremely Rare)

• Virtual impossibility between two healthy adults of equal strength unless victim is incapacitated (beaten, intoxicated, drugged)
• Possible in: children, very frail persons, unconscious victims
• Ligature mark may not show classic inverted-V; may be horizontal (victim hanged after strangulation)
• Other injuries of assault may be present
• Toxicological screen mandatory in all alleged suicides to rule out drug-facilitated hanging

H. JUDICIAL HANGING

• Involves a deliberate long drop (calculated based on body weight, typically ~5 meters)
• Knot placed on the left side of the jaw near the chin; trapdoor is released

• Fracture-dislocation of cervical vertebrae - at C2-C3 level ("hangman's fracture"), or atlanto-occipital/atlanto-axial joint; this fracture is actually uncommon even in judicial hanging (most victims show no fracture at all on autopsy, per postmortem studies)
• Instantaneous loss of consciousness and death due to cord transection
• Neck markedly elongated; may be severed from the body if the fall is too great
• Neck vessels (carotids, vertebrals) torn transversely
• Multiple intimal tears of carotid arteries at different levels (due to the long-drop traction force)
• Muscular contractions, facial twitching, and limb convulsions occur at the moment of the drop
• Heart may continue to beat for 8-20 minutes after unconsciousness
• X-ray: bilateral fractures of pedicles or laminae of arch of C2/C3/C4 with dislocation
• Ligature mark: Horizontal (knot placed anteriorly under chin/jaw), well-defined, at the level of the upper neck; may completely encircle the neck

VI. Comparative Summary Table

VII. Ligature Mark - Factors Affecting Appearance (Common to All Types)

1. Ligature material - hard/thin rope: deep, narrow, distinct; soft/broad cloth: shallow, wide, ill-defined
2. Duration of suspension - longer suspension = deeper, more prominent groove
3. Type of hanging - complete > partial in prominence
4. Tightness - tighter = deeper mark
5. Position of knot - deepest mark is always opposite the knot
6. Slipping of ligature - may produce a double impression
7. Presence of beard/hair/clothing - may prevent mark formation under it
8. Post-mortem changes - mark resists putrefaction; disappears if ligature removed soon after death; fades in decomposition

Lightning Injury: Mechanism, Death, Autopsy, and Fatalities

I. Definition and Physics of Lightning

• Current: ~20,000 amperes (range: kiloampere range on direct strike)
• Voltage: 100 million to 1,000 million volts (100 MV - 1,000 MV)
• Duration: Approximately 1/1,000th of a second (30 microseconds average contact time)
• Polarity: ~95% are negative discharges; ~5% are positive discharges (more common in mountainous regions and more dangerous)
• Although a flash appears single, research shows multiple strikes occur in rapid succession, cloud-to-earth and earth-to-cloud, appearing as one

Lightning vs. human-generated electricity: Lightning involves vastly higher voltage but an extremely brief contact duration. This brevity fundamentally changes the injury pattern - most energy passes over the victim rather than through them (the "flashover effect"), making lightning paradoxically less destructive to internal tissues than lower-voltage industrial electrical accidents.

II. Mechanisms of Injury (Types of Lightning Strikes)

1. Direct Strike

2. Side Flash (Side Splash / Ricochet)

3. Contact Voltage (Conducted Strike)

4. Ground Current (Stride Potential / Step Voltage)

5. Upward Streamer (Rare)

III. Four Factors Governing Lightning Injury

1. Direct electrical effect - current passing through the body to earth
2. Surface flash burns - discharge travelling over the body surface
3. Mechanical (blast) effect - violent displacement of air by thermal expansion around the flash; produces a concussive blast wave
4. Compression effect - the return wave of air causes additional pressure injury

IV. Mechanism of Tissue Injury

The Flashover Effect (Dominant Mechanism)

• Why most victims (~70-90%) survive
• Why deep muscle necrosis is rare (unlike industrial electrical injury)
• Why wet skin paradoxically reduces internal injury - wet skin acts as a better external conductor, keeping current on the surface

Direct Internal Injury Mechanisms

• Blunt mechanical force from the blast
• Direct current flow through body causing cardiac depolarization and respiratory centre paralysis
• Induction of current - the massive current in lightning creates a pulsed magnetic field that induces current flow in a nearby person even without direct contact
• Thermal injury - steam from rapid vaporisation of skin moisture, resistance heating of metal objects on/in clothing, heating of deeper tissues
• Intense photic stimulation - may damage retina or produce cataracts

V. Clinical Effects and Specific Organ Injuries

Cardiac

• Immediate cardiac arrest from massive depolarisation of the entire myocardium producing asystole (not ventricular fibrillation as in low-voltage AC current)
• Cardiac automaticity may spontaneously return, but if respiratory arrest persists, secondary hypoxic cardiac arrest follows
• In survivors: hypertension, tachycardia, various dysrhythmias (atrial fibrillation, PVCs, bundle branch blocks, non-specific ST-T changes on ECG)

Respiratory

• Immediate respiratory arrest from depolarisation and paralysis of the medullary respiratory centre
• Both cardiac and respiratory arrest may be present without any external injury
• The respiratory centre may remain paralysed longer than the heart - aggressive prolonged CPR is warranted

Neurological - Keraunoparalysis (Lightning Paralysis)

• Transient, immediate paralysis predominantly of the lower limbs (greater than upper limb weakness)
• Associated with extreme vasoconstriction - limbs pale, cold, pulseless (mimicking arterial injury)
• Sensory abnormalities of extremities
• Autonomic dysfunction may produce pupillary dilation or anisocoria - these are NOT reliable indicators of brain injury in comatose lightning-strike victims; they have no prognostic significance
• Amnesia and neurotic/confused behaviour may persist
• Usually resolves within 1 hour to a few days
• Associated with successful resuscitation after cardiorespiratory arrest

Ear

• Tympanic membrane rupture in approximately 81% of lightning victims (from barotrauma - air expands when superheated by the strike)
• Haemorrhage into the middle ear

Eye

• Thermal or photic retinal damage
• Cataracts (may develop days to months later)

Skin

Musculoskeletal

• Thrown by the blast - fractures from blunt trauma
• Scapular, humeral, femoral neck fractures from violent tetanic muscle contraction
• Vertebral fractures possible

VI. Cause of Death

1. Cardiopulmonary arrest - the most common immediate cause; massive myocardial depolarization causes asystole; simultaneous respiratory centre paralysis means both fail together
2. Direct electrothermal injury to vital structures from high-voltage direct current
3. CNS injury - direct involvement of the brain stem with paralysis of the cardiac or respiratory centre; subarachnoid and intracerebral haemorrhage
4. Asphyxia - secondary to sustained respiratory arrest (medullary centre paralysis)
5. Delayed death may occur from: aspiration pneumonia, hypoxic encephalopathy, cerebral oedema, sepsis from burns, thrombotic vascular complications

With a direct hit, death from burns and respiratory centre damage is almost inevitable. With a close but indirect strike, survival is possible - most lightning-injured individuals do survive.

VII. Autopsy Findings in Lightning Fatalities

A. External Findings

1. Clothing and General Appearance

• Clothing is torn, burned, or may be completely stripped off the body and thrown some distance; this can create suspicion of criminal violence
• Clothes are typically burnt or torn at the points of entry and exit of current
• In exceptional cases, clothing may be undamaged even when the person is killed, or conversely, clothing may be burnt with no injury to the person
• Shoes burst open or torn, especially at the sole (exit point through the feet)
• Belt and boots may be ruptured

2. Burns

• Zigzag or irregular linear burns, 3-30 cm or more in length, 0.3-2.5 cm in breadth
• Found preferentially in moist creases and skin folds (axillae, groin, popliteal fossae) because moist areas offer less resistance and conduct the surface current
• Also called filigree burns (filiform/thread-like pattern along skin)
• True superficial burns, often first-degree (erythema only)

• Pathognomonic (considered diagnostic) for lightning injury
• Superficial, thin, irregular and tortuous fern-like markings on the skin, resembling the branches of a tree or a fern leaf
• Appear within minutes to 1 hour of the incident
• Usually found over the shoulders, flanks, trunk, and chest
• Described as green in colour in some texts (due to copper-haemoglobin reaction)
• Mechanism: Produced by electron showers from the lightning, or by rupture of smaller superficial blood vessels giving ecchymoses in the arborescent pattern; boiling of intercellular fluid along fascial planes; haemoglobin from lysed RBCs staining the skin along the path of current. Possibly due to positive discharge flashover on the skin.
• They are not deep burns but rather areas of transient erythema / very superficial skin change
• Disappear within 1-2 days if the person survives - they must be documented immediately at autopsy as they fade rapidly
• Their relative rarity in autopsy is explained by: (a) they occur more with positive lightning discharges (only 5% of strikes), and (b) they fade quickly

• True thermal burns occurring beneath metallic objects worn or carried by the victim (rings, chains, spectacle frames, pen-knives, keys, watches, zip fasteners, belt buckles)
• These metal objects are superheated or even melted/fused by the flash
• Burns at these contact points are deeper and correspond in shape to the overlying metal

3. Entry and Exit Marks

• In cases where current enters and exits the body, entry marks (small, punched-out, charred) and exit marks (often larger, explosive-appearance) may be found
• Entry marks may be at the head (direct strike), point of contact with a conducted object
• Exit most commonly at the feet, causing burst shoes

4. Hair

• Hair is singed or seared at the point of entry; hair may be burnt off
• May form a characteristic pattern near the entry zone

5. Miscellaneous External

• Extensive ecchymoses of the trunk skin (from mechanical blast effect)
• Contusions, lacerations from being thrown or from blast injury
• Fractures (may be misinterpreted as assault)
• Ruptured tympanic membrane (found in ~81% of cases); bleeding from the ear
• Metallic objects fused or magnetised - ferrous metals (keys, coins, watches) on the body may be magnetised (diagnostic finding); nylon clothing may be melted
• Rigor mortis appears soon after death and passes off quickly

B. Internal Findings

• Haemorrhages under the pleura and pericardium (petechial/ecchymotic)
• Blood vessels may be thrombosed or ruptured
• Lungs are congested and oedematous, exude bloody serum (signs of asphyxia)

• Leptomeninges congested or lacerated
• Brain may be congested or oedematous
• Subarachnoid and intracerebral haemorrhage may occur
• The respiratory and cardiac centres in the medulla may show direct injury

• Tympanic membrane rupture with haemorrhage in the middle ear

• Tissues under the lightning mark are dry and whitened (histological: epidermis separated from papillary dermis)
• Ecchymoses in adjacent muscles

• Fractured bones (multiple sites - from blast, fall, or tetanic muscular contraction)

• Pulmonary haemorrhages and oedema
• Parenchymal necrosis

• Internal vessels show clots and thrombi
• Affected organs show necrosis and gangrene
• Intense oedema at the point of current entry

VIII. Lightning Fatalities - Epidemiology and Medicolegal Aspects

Epidemiology

• Lightning causes approximately 500 injuries per year in the USA, with 20-50 deaths per year
• Approximately 70-90% of persons struck by lightning survive; however, up to three-quarters of survivors have permanent sequelae
• Less than 3% of weather-related deaths are due to lightning (heat and cold are more deadly)
• Most deaths occur in outdoor settings: open fields, under trees, on water (fishing, boating), golf courses, camping
• Fishermen are the most commonly affected occupational group
• Lightning can occur without rain in approximately 10% of cases (so-called "bolt from the blue")
• Less than half of persons struck by lightning in India are killed

High-Risk Situations

• Standing in open fields or on hilltops
• Taking shelter under isolated tall trees
• Carrying or wearing metal objects (golf clubs, umbrellas, jewellery)
• Near metal fences, bleachers, plumbing, power lines, metal-topped structures
• On open water (boat, swimming)
• Indoor use of telephone or other wired electronics during a storm (contact voltage through wiring)
• Taking shelter in a doorway or window with an open chimney

Medicolegal Importance

1. Manner of death is always ACCIDENTAL - there are no recorded cases of homicidal or suicidal lightning death
2. The appearances can closely resemble criminal violence - contusions, lacerations, disarranged and torn clothing, fractured bones. A body found in a field with torn clothing and multiple injuries may initially be thought to be a homicide victim
3. Diagnosis rests on:
   • History of a thunderstorm in the vicinity at the time of death
   • Environmental evidence: damaged/burnt trees, dead cattle, scorched ground near the body
   • Arborescent/filigree burns (pathognomonic) on the body
   • Magnetised metallic objects on the victim's person
   • Torn, burnt, or stripped clothing and burst shoes
   • Burns beneath metal articles on the person
   • Exclusion of all other causes of death at autopsy
4. Persons in metal-bodied vehicles (cars, lorries) are generally safe - the charge travels over the metal surface rather than through the interior (Faraday cage effect)
5. Persons in buildings are generally safe as lightning passes along the outside of a conductor; however, indoor deaths have occurred via chimneys, aerials, plumbing, and telephone wires
6. Forensic pitfall: Magnetisation of ferrous objects and fusion of nylon or metal - these findings can help confirm lightning death and eliminate suspicion of foul play
