Article Synopsis
- Understanding gunshot residues (GSR) is essential for evidence preservation and linking suspects to crime scenes, focusing on how GSR behaves on various materials like ceramic, glass, metal, paper, and plastic.
- The study uses advanced techniques like scanning electron microscopy and energy dispersive X-ray analysis to quantify GSR particles (lead, barium, and antimony) and examines how different hand cleaning methods affect the transfer of these residues.
- Results show significant differences in GSR transferability across surfaces, with paper holding the most residues, and washing with water and soap leading to the greatest loss of GSR, highlighting the importance of surface properties and cleaning methods in forensic investigations.
Detection of GSR particles potentially indicates that a person fired a gun or somehow involved to a shooting event. GSR on the shooter's hand, face, and clothing may disappear within hours and with sweat secretion, washing or cleaning to remove evidences. Due to its anatomical properties, ears are relatively protected; therefore, we aimed to identify GSR particles on ears, to compare its anatomical parts of ears, and compare ears with common GSR sampling sites, based on firing frequency.
