Which item is listed as evidence collected from the victim that relates to gunshot residue?

• A. Victim's clothing
• B. Fingernail scrapings
• C. Hand swabs (gunshot residue)
• D. Hair samples

Answer: (C)

Gunshot residue testing focuses on particles that travel from a fired cartridge primer and can settle on the shooter’s hands. Collecting material from the hands with swabs provides the most direct evidence of contact with a firearm, because it targets the surface where residue would be deposited during firing or handling a weapon. The presence of residues such as the characteristic elements detected in GSR testing supports that the victim had recent firearm contact. Clothing can also carry residues, but it doesn’t pinpoint direct hand contact with the weapon. Fingernail scrapings and hair samples are less specific to immediate firearm contact and are not the standard method for establishing gunshot residue on the victim.
