BLUE-HIGHLIGHTED QUESTIONS - COMPLETE ANSWERS

IMAGE 1 - Q1 (Full question - number circled blue) [15 Marks - SMCH]

i) How do you help the police identify the deceased? (3 marks)

• Age (estimated by dentition, ossification centres, external appearance)
• Sex, height, weight, build
• Complexion, colour of hair, eyes

• Fingerprints - taken and sent to fingerprint bureau
• Scars, tattoo marks, birth marks, deformities, moles
• Dental examination - dental formula, fillings, prostheses
• Any surgical implants (pins, plates)
• Blood grouping from tissue samples

• Description of clothing, labels, manufacturer
• Contents of pockets - cards, keys, wallet

• DNA profiling from blood, hair roots, or teeth
• Dental X-rays for comparison with ante-mortem records

• Full body photographs of face and identifying marks, circulated to police and media

ii) How do you ascertain the wound as a firearm injury? (2 marks)

• Abrasion collar/ring (graze abrasion): A narrow, reddish-brown zone of abraded skin surrounding the wound, due to the bullet rubbing against skin as it enters
• Inverted/punched-in edges: The skin is pushed inward at entry
• Smaller than exit wound: Usually circular or oval
• Contusion ring: Bruising around the margin
• Soiling/blackening (at close range): Soot, smoke blackening, and powder tattooing/stippling around the wound depending on firing distance
• Wound track: Follows a straight line from entry toward exit, with hemorrhage along the track
• Muzzle contusion (contact shot): Cruciate laceration from gas pressure entering the wound

• Larger, irregular, everted edges
• No abrasion collar
• No blackening or tattooing

iii) How do you establish the cause of death? (3 marks)

• Note the entry wound characteristics, position, and any exit wound
• Document all injuries

• Dissect the wound track: identify the bullet path through chest wall, lungs, major vessels
• Hemorrhage in pleural cavity (hemothorax), hemopericardium, or pneumothorax
• Damage to heart, aorta, pulmonary vessels, or lung parenchyma
• Retain the bullet (if present) as forensic evidence

• Blood for grouping, DNA, toxicology
• Bullet/pellets from the wound track
• Swabs from wound for gunshot residue (GSR)

iv) How do you determine the Manner of Death? (3 marks)

• Body found in a roadside bush (unusual/secondary location)
• Unknown person - no identification
• Entry wound on mid-anterior chest - a typical homicidal location (front of chest)
• No weapon found at the scene
• Circumstantial evidence: being in a bush suggests body may have been disposed of

• Wound location: Mid-anterior chest - less accessible for self-infliction; more consistent with homicide
• Range of firing (see Q5): Close range vs. distant - distant wounds with no soot/tattooing more consistent with homicide
• Defense wounds: Check hands/forearms for defensive injuries
• Scene examination: Position of body, blood trail, footprints, cartridge cases
• No suicide note found

v) How do you determine the time since death? (4 marks)

• In India, rigor mortis begins in 2-3 hours (eyes/face first), then neck (5-7 hrs), then spreads downward
• Present in lower limbs only = approximately 9-12 hours since death (rigor has progressed down from head to lower limbs)

IMAGE 1 - Q2 (Blue-highlighted parts) [MCK]

Mechanism of the Pedestrian's Condition (Lucid Interval)

1. Primary Impact: The car hits the pedestrian from behind - the head strikes the road surface (secondary impact) causing a blow to the temporal region.
2. Momentary unconsciousness occurs due to the initial concussion (brief).
3. Lucid Interval: The patient regains consciousness - this occurs because the initial concussion is mild, but a bleeding middle meningeal artery (branch of external carotid) begins to bleed slowly.
4. Extradural hematoma formation: Blood accumulates between the skull and dura mater (extradural space), progressively compressing the brain.
5. Secondary unconsciousness (deterioration): As the hematoma enlarges, it causes raised intracranial pressure, tentorial herniation (uncal herniation), compression of the brainstem - the patient again loses consciousness.

Estimation of Firing Distance from Entry Wounds of a Rifled Firearm

Classification of Firing Range and Features

1. CONTACT SHOT (Muzzle touching skin)

• Cruciate (stellate) laceration: Hot gases enter the wound, expand beneath the skin, and tear it in a cruciate star-shaped pattern
• Blackening/singeing: Very dense soot deposited inside the wound canal and around edges
• Muzzle stamp/contusion: Impression of the muzzle on the skin (particularly in hard contact)
• Cherry red colour of tissues: Due to carbon monoxide in gases
• Soft contact: Less cruciate laceration, but all soot inside wound
• No external blackening (gases go into wound)
• Smell of burning

        ★ STELLATE LACERATION

2. CLOSE RANGE / NEAR CONTACT (Up to about 15 cm)

• Blackening/fouling/soot deposition: Dense black zone around wound
• Burning/singeing of hairs: Heat of flame singes hairs around wound
• Unburnt powder tattooing (stippling) may begin to appear
• Abrasion collar present
• Wound edges may be slightly lacerated

Summary Diagram of Firing Distance vs. Wound Features

FIRING     FLAME   SOOT/       TATTOOING    ABRASION
DISTANCE   BURNS   BLACKENING  (STIPPLING)  COLLAR
---------  ------  ----------  -----------  --------
Contact    Yes     Inside      None (inside) Yes
<15 cm     Yes     Dense       May start     Yes

>60 cm     No      None        None          Yes

Important Notes:

1. Tattooing cannot be wiped off (grains embedded in dermis) - distinguishes it from blackening (soot on surface, wiped off)
2. Firing distance estimates are for standard pistols/rifles; distance varies with weapon type, powder load, and barrel length
3. Intermediate zone: 15 cm to about 60-100 cm depending on the firearm
4. At very long range (>100 m): Entry wound is a clean circular hole with abrasion collar only
5. The abrasion collar (graze abrasion) is present at ALL ranges and is the hallmark of an entry wound from a rifled firearm

IMAGE 3 - Q3 (Blue-highlighted parts) [ICARE]

• "differentiate it from suicidal cut throat and homicidal cut throat injuries"
• "proceed for Post-Mortem Examination"

Differentiation of Suicidal Cut Throat vs. Homicidal Cut Throat (6 marks)

Proceed for Post-Mortem Examination if Person Dies During Treatment (4 marks)

1. Inform the Police Immediately

• Duty doctor/RMO to inform the on-duty police officer
• A formal complaint/intimation is sent under section of BNSS (formerly CrPC)
• An FIR or inquest report will be initiated

2. Preserve the Body

• Do not remove IV lines, catheters, endotracheal tubes, bandages
• The body must be handed over to police in exactly the condition found
• All attached medical/surgical instruments remain in situ (they are evidence)

3. Prepare Documentation

• Complete case summary including:
  • History obtained from police
  • Time and mode of admission
  • Clinical findings on admission
  • All investigations done (X-rays, CT scans, blood reports)
  • Treatment given (drugs, surgery)
  • Time and cause of death as determined clinically
• This constitutes the medicolegal records to accompany the body

4. Medico-Legal Post-Mortem (Autopsy)

• Inquest (under Section 194 CrPC / equivalent BNSS provision): Magistrate or Executive Magistrate orders the post-mortem
• MLR (Medico-Legal Report) is sent with the body
• A police requisition must accompany the body to the mortuary
• Post-mortem is conducted by a government forensic medicine specialist (not the treating doctor)
• The PM report documents: injuries found, cause of death (primary, secondary, contributory), manner of death

5. Samples to Preserve at Post-Mortem

• Blood, urine, viscera for chemical/toxicological analysis
• Histopathology of vital organs
• Preserve in labeled sealed containers

6. Treating Doctor's Role

• Cooperate with police and forensic team
• Provide complete clinical records
• May be called as a witness in court
• Must NOT certify cause of death - that is the forensic pathologist's role after PM

IMAGE 3 - Q4 (v) (Number 'v' circled blue) [BSMCH]

Conditions Simulating Rigor Mortis (Instantaneous Rigor)

1. Cadaveric Spasm (Instantaneous Rigor) - THE ACTUAL ENTITY

• Stiffening of muscles immediately after death without preceding primary relaxation
• Conditions required:
  • (a) Somatic death must occur extremely rapidly
  • (b) Person must be in a state of great emotional tension
  • (c) Muscles must be in a state of physical activity at time of death
• Usually involves groups of muscles (forearm, hands); occasionally whole body
• Classic example: Knife grasped firmly in suicidal cut-throat; grass/weeds in hands of drowning victims; hair in victim of homicidal scuffle
• Impossible to simulate artificially after death
• Medico-legal importance: Object held in hand proves it was grasped at the moment of death (not placed there after)

2. Freezing / Cold Stiffening

• Occurs when a body is exposed to freezing temperature
• Tissues become frozen and stiff - resembles rigor
• On thawing: Stiffening rapidly disappears and the body then goes into rigor (which comes on rapidly, lasts less time, and is less intense)
• Occurs in high altitudes (Himalayas, Kashmir) or in cold chamber mortuaries at 4°C

3. Heat Coagulation / Heat Stiffening

• Occurs when body is subjected to temperatures above 70°C (burning, high-voltage electrocution, falling into vat of hot liquid)
• Heat coagulates muscle proteins - causes stiffening and contraction greater than in rigor mortis
• Body assumes the "pugilistic (boxer's) attitude": lower limbs and arms semi-flexed, hands clenched
• Normal rigor mortis does NOT develop in these cases
• Stiffening persists until coagulated albumin liquefies during decomposition

4. Putrefaction / Cadaveric Bloating

• Stiffening due to accumulation of putrefactive gases in tissues
• Causes "false rigidity" - limbs can be held up without support
• Easily distinguished by presence of decomposition (green discoloration, bloating, foul odour)

Summary Table

COMPLETE ANSWERS - ALL QUESTIONS (IMAGE 3)

QUESTION 1 [15 Marks - PCSGMCH]

a. State Probable Cause and Manner of Death with Explanation (2 marks)

• The three spindle-shaped (stab) wounds converging toward the right lung indicate penetrating stab injuries of the chest causing damage to lung parenchyma and major vessels → hemothorax / pneumothorax / hemopneumothorax leading to cardiorespiratory failure.
• The incised wound on the right palm is consistent with a defense wound (victim tried to grab the weapon).

• Multiple stab wounds (three) of the chest wall targeting vital structures (lungs) → not self-inflicted
• Defense wound on the right palm = victim attempted to protect himself
• Imprint abrasions around wounds suggest the weapon was thrust in forcefully with a guard/hilt striking the skin
• Location of body on roadside in torn, blood-stained clothing = likely disposed of after death
• Alcohol smell in stomach suggests victim may have been intoxicated (making him a vulnerable target)
• A single suicidal stab is rare; three stabs are virtually never suicidal

b. Estimate the Time Since Death (2 marks)

c. Identifying Data in PM Report and Samples for Future Identity Confirmation (2+2 = 4 marks)

• Estimated age (~60 years based on dentition, grey hair, skin laxity)
• Sex (male)
• Height, weight, built
• Complexion, colour of hair, eyes
• Nutritional state

• Fingerprints: Taken (rolled impressions of all 10 fingers) and submitted to fingerprint bureau
• Dental examination: Full dental formula - missing teeth, crowns, fillings, prostheses; dental X-rays
• Scars, tattoos, birthmarks, deformities, moles - locations documented
• Surgical scars or implants (pins, joint replacements)
• Clothing description: Type, colour, size labels, manufacturer tags

1. Blood sample - for DNA profiling and blood grouping
2. Tooth (preferably a molar) - most stable source of DNA; resists putrefaction
3. Hair with roots - for DNA analysis and hair characteristics
4. Nail clippings - for DNA and trace evidence
5. Bone sample (if needed later) - tibia/femur most preferred for long-term DNA
6. Fingerprints on record (latent + rolled)
7. Photographs of face, identifying marks, full body

d. Describe the Suspected Weapon Used (2 marks)

• Three spindle-shaped wounds = consistent with a single-edged knife (one end of wound is acute/pointed, other end may be wedge-shaped or blunt)
• Imprint abrasions around the wounds = the weapon was fully driven in until the hilt/guard struck the skin, leaving a patterned abrasion corresponding to the shape of the guard
• Convergent direction (right to left, extending to lung) = deep penetrating blade

• A blade length sufficient to reach the right lung (at least 8-10 cm, likely 10-15 cm based on depth to lung)
• A hilt/guard present (causing imprint abrasions)
• Sharp-pointed tip (penetrated chest wall easily)
• Possibly 2-3 cm wide blade (spindle wounds 2-3 cm length when edges brought together)

e. Why Depth of Injury Over Anterior Chest Wall to the Lung Does NOT Necessarily Correspond to Length of the Weapon (3 marks)

1. Compression of chest wall: When the blade is thrust forcefully, the soft tissues of the chest (skin, subcutaneous fat, muscle, intercostal muscles) are pushed inward ("compressed inward") before being penetrated. Once the blade is withdrawn, the compressed tissues spring back to their original position, so the apparent depth of the wound track is greater than the blade length.
2. Respiratory movement: If the victim inhales deeply during stabbing, the lung moves upward and the chest wall compresses - the weapon can penetrate deeper.
3. Body falling/running on the weapon: The momentum of the body adds force, driving the weapon deeper.
4. Movement of attacker: The attacker may push forward with additional body weight.

1. Resistance by bone/cartilage: If the tip of the blade strikes a rib, sternum, or calcified costal cartilage, it cannot penetrate further, making the depth less than blade length.
2. Clothing resistance: Thick layers of clothing reduce penetration depth.
3. Weapon not fully driven in: Attacker may not have used full force.
4. Blade flexibility: A flexible blade may bend, reducing effective depth.
5. Angle of entry: Oblique rather than perpendicular entry reduces depth.

QUESTION 2 [15 Marks - MLDMCH]

* How will you determine the nature of offending weapon from shape & size of wounds? (4 marks)

• The length of the stab wound (measured with wound edges brought together) approximately equals the maximum width of the blade at the depth of penetration
• The wound gapes across its center due to Langer's lines - the actual wound length may be wider than blade; bring the edges together to get true blade width

• Single-edged knife: One end of the wound is acute (sharp edge), the other is blunt/wedge-shaped (back/spine of blade)
• Double-edged: Both ends acute and pointed
• If there is a "V" or fishtail appearance at one end → indicates the back of a single-edged blade

• If the blade was fully driven in, the hilt/guard leaves an imprint abrasion on the skin, indicating the shape of the guard and the maximum width of the blade
• Symmetrical hilt mark = perpendicular entry; asymmetrical = angled entry

• Examining multiple wounds helps confirm blade dimensions - the most consistent measurements across wounds give the most reliable blade dimensions

* How will you assess their depth? (3 marks)

1. Imaging:
   • X-ray chest and abdomen: Reveals pneumothorax, hemothorax, pneumoperitoneum (free air), or metallic foreign bodies
   • CT scan (most reliable): Traces the exact wound track, identifies organ injuries, hematomas, depth of penetration
2. Clinical signs:
   • Absent/diminished breath sounds → lung injury/hemopneumothorax
   • Peritoneal signs (guarding, rigidity, tenderness) → intra-abdominal organ injury
   • Hypotension, tachycardia → internal hemorrhage suggesting deep penetration
3. At Autopsy (if patient dies):
   • Insert a pliable tube/catheter gently into the wound - do NOT use rigid probe before in situ organ examination
   • Dissect tissues parallel to but away from the wound to reveal the track
   • Radioopaque dye or contrast can be injected and X-ray/CT done to demonstrate track length
   • After evisceration, a probe is inserted from the skin surface through the wound channel through injured organs to the termination point
   • Measure depth directly with a ruler
4. Factors affecting depth (to interpret findings):
   • Elastic recoil of tissues: Apparent depth at autopsy may exceed blade length (see Q1e)
   • Bone obstruction: May limit depth

* Why depth of stab injuries over chest & abdomen may NOT correspond with the length of the weapon? (5 marks)

1. Compression of abdominal wall: Soft, compressible abdomen (especially obese or lax wall) is pushed inward by the blade before penetration. On withdrawal, it springs back, making the track longer than the blade.
2. Chest wall compression: Intercostal spaces and soft tissues are compressible; same principle applies.
3. Body movement during stabbing: If victim runs/moves onto the blade or the attacker thrusts forward with body weight, depth is increased beyond simple blade penetration.
4. Respiratory movement: Deep inspiration raises the dome of the diaphragm and the liver/spleen; the blade can reach organs it would not reach during expiration.

1. Bony obstruction: Ribs, sternum, costal cartilages (especially calcified in older individuals), iliac crest, or vertebral bodies can stop the blade short of its full length.
2. Clothing resistance: Multiple layers of thick clothing absorb energy and reduce penetration.
3. Blunt tip: Even a long blade with a blunt tip cannot penetrate easily; the weapon may bend rather than penetrate.
4. Oblique angle of entry: A blade entering obliquely tracks at an angle; the straight-line depth is less than the wound track length.
5. Partial penetration: The attacker may not have applied full force, not driving the blade to its full length.

* Give your opinion about the nature of the injuries whether homicidal or suicidal? (3 marks)

1. Multiple wounds on different body regions (chest AND abdomen) - suicidal stabs almost never occur on the abdomen; the chest (precordium) is the classical suicidal site
2. Abdominal stab wounds are almost always homicidal - a person cannot easily self-inflict abdominal stabs
3. Defense wounds may be present on the hands/forearms (look for them) - strong evidence of homicide
4. No hesitation cuts expected in homicidal injuries
5. Distribution on different body surfaces (front of chest + abdomen) - suggests multiple assaults by another person
6. Clean-cut wound edges without hesitation - homicidal
7. Clothes may be cut/torn - consistent with assault
8. Scene of crime - if brought from outside with disturbed scene, more likely homicide

• Suicidal stabs are usually on the left precordial region (over the heart), multiple but clustered, with hesitation cuts nearby
• Suicidal abdominal stabs are extremely rare (hara-kiri is a cultural exception)

QUESTION 3 [15 Marks - ICARE]

Define Injury (1 mark)

"Whoever causes bodily pain, disease or infirmity to any person is said to cause hurt."

How will you differentiate Homicidal Cut Throat from Suicidal Cut Throat Injuries? (6 marks)

Responsibilities of the Registered Medical Officer (RMO) in Such a Case (4 marks)

1. Immediate life-saving treatment: Secure airway (intubation if needed), control hemorrhage (direct pressure, surgical ligation), IV access, blood transfusion, resuscitation - treatment takes priority over medico-legal formalities.
2. Medico-Legal Register (MLR):
   • Record all details: Time and date of admission, history as given by police, clinical findings on examination
   • Describe all injuries in detail: site, size, shape, margins, depth, associated features
   • Do NOT opine on cause in the MLR prematurely; record objective findings only
3. Inform Police:
   • Send written intimation to the nearest police station under Section 39 CrPC (now BNSS) - this is mandatory for all medico-legal cases
   • Inform police officer on duty about the patient's admission
4. Preserve evidence:
   • Do NOT discard or destroy any clothing, instruments, or items brought with the patient
   • Preserve blood-stained clothing, foreign bodies (knife fragments) in sealed labeled bags
   • Note time of treatment, drugs given, surgical procedures done - this is crucial if the case goes to court
5. Consent: In emergency life-threatening conditions, implied consent applies; formal consent may be obtained from family as soon as possible.
6. Maintain chain of custody: Any specimen (blood, swabs, foreign bodies) collected must be handed to police with proper documentation.
7. Confidentiality: Information shared only with authorized police/judicial officers, not media.

If the Person Dies During Treatment - How to Proceed for Post-Mortem Examination (4 marks)

1. Do NOT remove supportive equipment:
   • Leave IV cannulae, endotracheal tube, nasogastric tubes, drains, surgical packing - all in situ
   • These are evidence of treatment and also help the forensic pathologist understand what interventions were done
2. Certify Death:
   • Time of death noted and recorded
   • The treating doctor certifies clinical death (NOT the cause of death - that is the forensic pathologist's role)
   • Do NOT issue a death certificate in a medico-legal case
3. Inform Police Immediately:
   • Written intimation of death sent to police station
   • Police will initiate inquest proceedings under Section 174 CrPC (now BNSS Section 194)
4. Preserve the Body:
   • Hand over the body to police exactly as it is
   • Tag the body clearly with name/registration number, time of death, treating doctor's name
   • Body must NOT be handed to relatives directly
5. Prepare Clinical Summary/Case Records:
   • Detailed summary including:
     • History of incident
     • Clinical findings on admission
     • All investigations (X-rays, CT reports, blood reports)
     • All treatment given (medications, surgeries)
     • Clinical cause of death
   • This accompanies the body to the mortuary as part of the medico-legal record
6. Post-Mortem by Forensic Pathologist:
   • Government forensic medicine specialist performs the autopsy
   • Order for PM comes from Magistrate or police (Section 174/176 CrPC equivalent)
   • Treating doctor does NOT conduct the PM (conflict of interest)
   • PM report establishes: injuries, cause of death, manner of death
7. Treating Doctor as Witness:
   • May be summoned to court to give evidence about clinical findings, treatment, and time of death
   • All records must be preserved for at least 5 years (or as per hospital policy)

QUESTION 4 [15 Marks - BSMCH]

(i) What might be the Manner of Death? (1 mark)

• Location of wounds: LOW (below thyroid cartilage) → classic homicidal level
• Beveling upwards → consistent with weapon drawn from below upward by an attacker standing behind/in front
• No tailing → homicidal (tailing is a feature of suicidal wounds)
• No hesitation cuts → homicidal
• Clean-cut beveled margins → homicidal
• Three wounds → multiple deep cross-cutting wounds without the parallel pattern of suicide
• Jugular veins AND carotid arteries cut → in suicidal cut-throat, the carotid usually escapes; injury to both jugulars AND carotids suggests homicide
• Knife held loosely → NOT firmly grasped with cadaveric spasm (which would be the case in suicidal cut-throat); the loose grip suggests the knife was placed in the hand postmortem to simulate suicide
• Body found on rooftop of own house → while a private/quiet location can be suicidal, the overall wound pattern overrides this

(ii) What are the Differences Between Homicidal and Suicidal Cut Throat? (5 marks)

(iii) Write the Medico-Legal Importance of Incised Wound (4 marks)

1. Nature of weapon:
   • Clean, sharp, linear edges → sharp-edged weapon (knife, razor, sword)
   • Serrated edges → serrated knife or saw
   • The length and shape of the wound helps identify the class of weapon
2. Determination of manner of death (suicidal/homicidal/accidental):
   • Suicidal incised wounds: Multiple tentative (hesitation) cuts parallel to the main wound; typically on accessible sites (wrists, neck, groins, thighs, ankles); clothes usually not cut
   • Homicidal incised wounds: Usually single deep cut; defense wounds on hands and forearms; clothes cut corresponding to body wounds; scene of struggle
   • Accidental: Irregular distribution; history of accident; clothing damaged correspondingly
3. Hesitation marks:
   • Multiple superficial parallel incisions (hesitation cuts) before the main wound → strongly suggest suicidal intent
   • Their absence in deep single wounds → more likely homicidal
4. Defense wounds:
   • Incised wounds on the back of the hand, fingers, forearms → victim tried to grab or deflect the weapon → homicidal assault
5. Vital reaction:
   • Helps determine whether wound was inflicted before or after death
   • Antemortem: bleeding, bruising, inflammatory response
   • Postmortem: yellow/tan parchmented margins, no bruising
6. Age of wound:
   • Healing stages can help determine when the wound was inflicted
7. Position of the body and relative positions of attacker/victim:
   • Direction of wound track and tailing indicate relative positioning

(iv) Define Cadaveric Spasm and What is its Medico-Legal Importance? (3 marks)

1. Somatic death must occur with extreme rapidity
2. The person must be in a state of great emotional tension at the time of death
3. The muscles must be in a state of physical activity at the moment of death

• Usually involves particular groups of muscles (forearm and hands most commonly)
• In cases of extreme nervous tension, the whole body may be affected
• The contraction is more pronounced than in ordinary rigor mortis (requires greater force to break)
• It is impossible to simulate cadaveric spasm after death

1. Distinguishes suicide from homicide:
   • A knife firmly grasped in the hand due to cadaveric spasm in a cut-throat case = strongly suggests suicide (the victim held the knife themselves at the moment of death)
   • A knife placed loosely in the hand AFTER death will not show cadaveric spasm → suggests the knife was placed postmortem = staged scene (as in Q4, where knife was loosely held)
2. Proves the object was held at the moment of death:
   • Grass/weeds grasped in a drowning victim's hand = victim was alive when they entered the water
   • Hair grasped in hand = victim grasped hair of assailant during a homicidal struggle
3. Cannot be induced postmortem:
   • Cadaveric spasm CANNOT be artificially reproduced after death; an object cannot be placed in the hand after death and made to look like cadaveric spasm - the force required to open the hand in cadaveric spasm is much greater than in rigor mortis
4. Sign of Death:
   • Confirms somatic death has occurred with certainty
5. Time of death:
   • Indicates that death occurred suddenly and with great emotional/physical stress, which helps reconstruct the circumstances of death

(v) Name the Conditions Which Simulate Instantaneous Rigor (2 marks)
