residues and bullet exiting

When a firearm is discharged and the bullet strikes a surface, gunshot residues are deposited, particularly at close range. These residues may be reproducible and therefore have evidentiary value. Some residues are visible and others require chemical treatment in order to visualize them.

Note:
Evidence should be received and handled according to laboratory protocol.
