To identify the type of gunshot wound described, we need to analyze the characteristics mentioned: burning, blackening, tattooing around the wound, and a dirt collar.
1. Burning and Blackening: These are typically produced by the hot gases and smoke emitted from a firearm when discharged. The proximity of the gun to the target is crucial because these effects diminish with distance.
2. Tattooing (Powder Tattooing/Stippling): This refers to the embedding of gunpowder particles in the skin, which happens only when the firearm is in close proximity. The powder does not travel far and embeds into the skin only within a close range.
3. Dirt Collar: This is a grayish ring around the entrance wound caused by the non-burnt gunpowder and soot marks. It is indicative of the entry wound at close range.
Considering these features:
Therefore, the described injury features confirm that it is a Close shot entry wound.
