AFTE Store - Physical Matching as Duties of a Firearms and Toolmark Examiner

Two objects or surfaces that have been in contact with each other for any period of time should (under most circumstances) leave their respective markings or traces upon one another. Through careful examination and comparison such markings and traces can be detected, possibly leading to the conclusion that the two objects or surfaces were in fact joined or in contact with each other. This case examination profiles a rare and unique dual-impression.
