What’s the difference between exit and entrance wounds?
Edges: Usually the edges of entrance wound are inverted and that of exit wounds are everted. But it can also be everted in case of entry wound if there is fatty tissue or firm contact over shallowly situated bone.
Can a bullet cause an entrance and exit wound?
Of course entrance and exit wounds can be made if an individual is stabbed with a large sharp knife or spike but as already mentioned more often than not the wounds are created by a bullet entering the body and leaving through another area of the body.
What kind of residue is found on an entrance wound?
Entrance wounds are often ringed with the residue of gunpowder and cordite – the two substances contained within a bullet. A close range gunshot – if the weapon is touching the victim’s body – will normally have what is known as an ‘abrasion ring’ and also a clear imprint of the weapon’s barrel.
Why does an entrance wound have a ring around it?
Entrance wounds will usually have some kind of discolouration around them; perhaps a black or grey ring caused by the burning of the gunpowder as it makes contact with the skin. ‘Tattooing’ as it is sometimes referred to, is when the gunpowder will spray around the area of the wound and burn to the skin as it is hot on being fired from a weapon.
