Method of use of taggants

摘要

An investigation process includes dispersing particulate taggants at a transit point with recordation of the transit point location. A subject passing the transit point has adhered to them at least one taggant from the transit point. Collection of the at least one taggant from the area of investigation allows an investigator to assign the location of the dispersal step to a path taken by the subject between the transit point and the area of investigation.
