 | | There is a principle in homicide investigation that refers to a theoretical exchange between two objects that have been in contact with one another. |
 | | This theory of transfer or exchange is based on Locard's "Exchange Principle." Edmond Locard, a Frenchman, who founded the University of Lyons' Institute of Criminalistics, believed that whenever two human beings came into contact, something from one was exchanged to the other, and vice-versa. |
 | | This exchange might involve, hairs, fibers, dirt, dust, blood and other bodily fluids, as well as skin cells, metallic residue and other microscopic materials. |
