Study Notes
Wound Characteristics
- Entry Wound Size: Typically smaller compared to exit wounds, indicating the initial point of projectile impact.
- Exit Wound Size: Larger than entry wounds, often due to the expansion of the projectile or tissue damage during exit.
- Edge Appearance: Entry wound edges are usually inverted, suggesting that tissue is pushed inward as the projectile enters.
- Exit Wound Edges: Everted edges are common, reflecting the outward pulling of tissue during exit.
- Abrasion and Grey Rings: Present in entry wounds, indicating skin abrasion and soot or residue from the projectile.
- Smudging: Often associated with the entry wound; specific details not provided.
- Tattooing: May be present around entry wounds due to the dispersion of gunpowder, while absent in exit wounds.
- Singeing: Evidence of burning may be found in entry wounds but is absent in exit wounds.
- Muzzle Impression: Not specified; relevant details needed for clarity on its presence in entry or exit wounds.
- Bleeding: Generally, entry wounds produce less bleeding compared to the more profuse bleeding typically seen with exit wounds.
- Cherry Red Colour: May be observed in entry wounds, possibly indicating carbon monoxide presence, while absent in exit wounds.
Wound Characteristics
- Entry Wound Size: Generally smaller than exit wounds, indicating the initial penetration point.
- Exit Wound Size: Typically larger than entry wounds due to the expansion of tissue and tissue disruption.
Wound Edges
- Entry Wound Edges: Characterized by inverted edges that may fold inwards.
- Exit Wound Edges: Notable for everted edges that protrude outward, suggesting a violent expulsion from within.
Associated Markings
- Abrasion and Grey Rings: Entry wounds often exhibit the presence of abrasions and grey rings, which may indicate intermediate range firing.
- Exit Wound Markings: Generally show an absence of abrasions and grey rings, simplifying the analysis.
Tattooing and Other Features
- Tattooing in Entry Wounds: May be observed in entry wounds, indicating gunpowder particles depositing on the skin.
- Tattooing in Exit Wounds: Absent, as particles are expelled outward without remaining on the surface.
Bleeding Patterns
- Bleeding from Entry Wounds: Usually leads to less bleeding due to the narrow channel of penetration.
- Bleeding from Exit Wounds: Presents more bleeding, as the larger wound allows for greater blood loss.
Unique Visual Characteristics
- Cherry Red Colour in Entry Wounds: This distinctive coloration may be present due to the presence of carbon monoxide, signaling potential immediate death or close-range firing.
- Cherry Red Colour in Exit Wounds: Typically absent, indicating a lack of such immediate effects.
Additional Observations
- Smudging and Singeing: Specific details regarding smudging and singeing are not noted, indicating further investigation may be necessary for comprehensive analysis.
- Muzzle Impression: Lack of information on muzzle impression suggests no clear evidence of contact-related injuries or patterns observed.
Entry and Exit Wound Characteristics
- Size: Entry wounds are typically smaller in diameter while exit wounds are larger due to the projectile's passage through the body.
- Edges: Edges of entry wounds are inverted, meaning they are pushed inward, whereas exit wounds have everted edges, showing outward bulging.
- Abrasion and Grey Rings: Presence of abrasion rings and grey rings around entry wounds indicate forceful contact. These are typically absent in exit wounds.
- Smudging: Often associated with entry wounds due to gunshot residue; usually not applicable to exit wounds.
- Tattooing: Entry wounds may show tattooing due to burning gunpowder, while exit wounds do not exhibit this feature.
- Singeing: Entry wounds may present singeing due to proximity to the fired weapon; exit wounds typically lack this characteristic.
- Muzzle Impression: Reflects the point of firing; present only in entry wounds, highlighting contact with a weapon's muzzle.
- Bleeding: Entry wounds tend to bleed less due to smaller size and less immediate tissue damage compared to exit wounds, which cause significantly more bleeding.
- Cherry Red Color: Often observed in entry wounds, indicating carbon monoxide presence or asphyxiation; this coloration is absent in exit wounds.
Wound Characteristics
- Entry wounds are typically smaller compared to exit wounds, which are larger.
- The edges of entry wounds are usually inverted, while exit wounds have everted edges.
- Entry wounds may show abrasion and grey rings, while exit wounds generally do not.
- Smudging may occur around both types of wounds, indicating the proximity of the firearm when fired.
- Tattooing can be present at entry wounds, resulting from unburned powder particles; this is absent in exit wounds.
- Singeing may occur on the skin surrounding entry wounds due to hot gases, but is not usually found at exit wounds.
- Muzzle impressions can be seen at entry wounds, signifying close-range firing; exit wounds do not retain this feature.
- Bleeding from entry wounds tends to be less severe, in contrast to exit wounds, which often exhibit more bleeding.
- Cherry red coloration may be observed in entry wounds, while this color is absent in exit wounds.
