Particle Combination Analysis or PCA is a new approach that uses co-occurring particles to test alternative attribution hypotheses. Simply put, Particle Combination Analysis exploits the particles in dusts, which are ubiquitous and in infinitely varying combinations, to solve a wide range of problems with varying case specifics.
PCA is used to:
Produce particle combination profiles from seized weapons, explosives and contraband that readily identify links between different crimes, events and people
Rapidly narrow a search so investigators can focus activity on a small area
Identify characteristics of the nearby environment that will aid in a search - vegetation, commercial activity, proximity to roads and bodies of water, etc.
Infer the origins and assembly sites of items of interest - country, city, specific building
This approach can provide a game-changing capability to forensic investigators, working alongside existing investigative methods and using portions of evidence that are typically discarded or ignored. The approach utilizes existing staff and laboratory resources, so it does not require major investments in training, equipment, or retention of outside experts. It does require changes in the way some of these resources are used.
