Which forensic field is focused on gunshot residue analysis?

• A. Forensic biology
• B. Firearms examination
• C. Toxicology
• D. Trace evidence analysis

Answer: (B)

The field focused on gunshot residue analysis is firearms examination. This area of forensics specifically deals with the analysis and comparison of firearms, ammunition, and the physical evidence related to the discharge of a firearm. Gunshot residue (GSR) analysis is crucial because it helps forensic experts determine if a person has discharged a firearm or been in close proximity to one when it was fired. Firearms examiners use specific tests to detect GSR particles on a suspect's hands, clothing, or other surfaces. The presence of these residues can provide critical evidence in criminal investigations involving shooting incidents. Other fields such as forensic biology, toxicology, and trace evidence analysis focus on different types of evidence and biological samples. For instance, forensic biology typically entails analyzing biological tissues or fluids, toxicology involves studying the effects of drugs and poisons, and trace evidence analysis focuses on small materials such as fibers, hair, or paint. Each of these fields has its unique emphasis, making firearms examination the appropriate choice for gunshot residue analysis.
