Two NIJ-funded studies examine new ways to analyze trace evidence in the aftermath of an explosion or bombing.

NIJ-funded researchers create unprecedented gunshot residue dataset to develop a quick, dual-detection method for gunshot residue detection.

Nanoparticles and other subvisible particles potentially present in nearly all trace evidence are often overlooked in forensic investigations. NIJ-supported researchers have characterized several types of particles and developed detection methods.

Fiber evidence has long been an important part of criminal cases, for it can associate a suspect with a crime scene. This project details new analytical procedures that allow fiber comparisons that are more detailed than standard forensic practices.

Two researchers with a long record of research into the forensic value of very small particle populations examined cell phones, handguns, drug packaging, and ski masks from the San Diego County Sheriff’s Office to determine if such particles can make phys

The ability of Laser Induced Breakdown Spectroscopy (LIBS) instruments to detect practically the entire periodic table of elements very quickly and without the complexity of other systems makes them an economic choice for forensic analysis.

Criminals track dust particles to and from virtually every crime scene, but particles on a suspect’s shoes are seldom used as evidence linking the accused to the crime. In this NIJ-supported project, researchers assert that investigators can use small par
