Answer:
Step-by-step explanation:
The circular entrance wound with black edges and a stippling pattern emanating outward from the center was most likely caused by a pistol fired at close range. The characteristics of the wound, including the circular shape, the black edges, and the stippling pattern, are typical of a contact wound, which is a wound caused by a firearm that is fired at a very close range to the victim's skin. This type of wound is often seen with pistols, which are small, handheld firearms that are often used at close range. In contrast, a shotgun fired from a distance would not produce a circular wound with black edges and stippling, and a rifle fired from a distance would not produce a circular wound at all. A shotgun fired at close range could potentially produce a circular wound, but it would not have the same black edges and stippling pattern as a pistol fired at close range. Therefore, the most likely cause of the wound described in the question is a pistol fired at close range.
