Q: The following image shows a victim of a firearm injury. What is the suspected distance of the shot?

Intermediate range. ***Intermediate range*** - The image distinctly shows **stippling** (or tattooing), which consists of multiple small abrasions caused by **unburnt powder grains** impacting the skin. This pattern is characteristic of a shot fired from an intermediate range, typically 15 cm to 1 meter (6 inches to 3 feet). - The absence of a large **soot deposition** (fouling) and the presence of scattered powder grains confirm that the firearm was not fired at a very close or contact range. *Close range* - A close-range shot, usually within 10-15 cm (4-6 inches), would typically show **fouling** (blackening by soot) around the wound, in addition to minimal stippling. - The image does not display the extensive blackening or prominent soot deposition expected from a close-range shot. *Point blank range* - A point-blank (contact) shot implies the muzzle of the firearm was in direct contact with the skin, resulting in an **imprint of the muzzle** and significant **soot and gas forcefully driven into the wound track**. - Such shots often produce a stellate (star-shaped) wound due to gas expansion, and lack the widespread scattered stippling observed in the image because powder is deposited within the wound. *Distant shot* - A distant shot, typically beyond 1-1.5 meters (3-5 feet), would show **neither fouling nor stippling**. - Only the bullet perforates the skin, leaving a simple entrance wound without any surrounding marks from powder or gases.
