crime scene investigation

UAlbany

Researchers at the University at Albany are developing a fast, accurate method for crime scene investigators to detect and recover gunshot residue from a crime scene or suspect. The process has a promising future.

For years, New York's gun control lobby pushed hard in favor of a process that involves a gun's firing pin stamping cartridges with unique identifying numbers.
