Annotation

This paper presents an improved method for firing distance determination on exhibits that cannot be processed in the laboratory--such as cars, doors, windows, and furniture.

Abstract

The novel part of the method includes the transfer of total nitrite (nitrite ions and smokeless powder residues) from the target to an adhesive lifter. After the transfer, vaporous lead and copper deposits around the bullet entrance hole are visualized on the target by sodium rhodizonate and rubeanic acid, respectively. The Modified Griess Test is carried out after alkaline hydrolysis of the smokeless powder residues on the adhesive lifter. 2 references and 4 figures
