What is Firearms and Toolmarks Analysis?
Firearms and toolmarks analysis examines the microscopic marks left behind by tools (such as firearms, screwdrivers, pry bars and bolt cutters). The goal is to determine whether a specific firearm or tool was used in a crime.
What is NIST’s Role?
Our experts:
- Create standards and reference materials to help forensic laboratories test their analytical methods.
