All the biopsies analyzed here were from patients killed as consequence of the injury they received. The biopsies were dissected purposefully in order to select fragments of tissues at progressive depth from the point of impact of the weapon: for N5 is compared metal content in the surface of the wounded skin to that in deeper tissue layers not directly severed by impact; for N7 is compared metal content in the surface of the wounded skin with that of exposed lamellar bone and than of more internal trabecular bone; for R1 is compared metal content in muscle exposed by the wound with underlying soft tissue; for R2 is compared metal content in blackened bone with not burned muscle. Similarly prepared fragments of N5 were analyzed in 3 different laboratories, those of N7, R1 and R2 in 2 laboratories.
