Improved method for shooting distance determination. Part 2 - Bullet holesin objects that cannot be processed in the laboratory

An improved method for firing distance determination on exhibits that canno t be processed in the laboratory such as cars, doors, windows, or furniture is described. The novel part of the method includes transfer of total nitr ite (nitrite ions and smokeless powder residues) from the target to an adhe sive lifter. After the transfer, vaporous lead and copper deposits around t he bullet entrance hole are visualized on the target by sodium rhodizonate and rubeanic acid, respectively. The Modified Griess Test is carried out af ter alkaline hydrolysis of the smokeless powder residues on the adhesive li fter.
