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.
