Question

The range of fire by a rifled firearm per the image:

• A. Contact
• B. Close
• C. Distant
• D. Cannot be opined

Hint:

Close-range firing can often be identified by the presence of gunshot residues on the victim or target, and the spread of the wound pattern.

Answer 1

The Correct Option is B

In forensic biology, determining the firing range of a rifled firearm involves analyzing specific patterns and characteristics of the gunshot residue and damage to the target. Here's how you can determine the range as "Close" based on the observations:

1. Residue and Burn Marks: If the firearm was discharged at a close range, gunshot residue (GSR) will be present around the entry wound. Additionally, close-range firing can produce visible burn marks or smudges due to high-temperature gases.
2. Pattern Distribution: At close range, the spread or pattern of gunshot residue is concentrated and dense. The grains of powder may remain around the wound, offering clear visual clues that indicate proximity.
3. Bullet Entry Characteristics: The size, shape, and distinct characteristics of the entry wound can provide clues. Close-range shots often result in larger, more irregular wound margins due to the impact force.

Thus, based on these characteristics, the observed result implies a "Close" range of fire, consistent with the correct answer choice.
