Annotation

A PRACTICAL, INEXPENSIVE, AND RAPID METHOD TO ANALYZE LEAD CONCENTRATION PATTERNS AROUND BULLET HOLES IS DESCRIBED AND RESULTS FROM SIMULATED CASES ARE REPORTED.

Abstract

THE SECTIONS AROUND THE BULLET HOLES ARE REMOVED AND SOAKED IN 4 MOLAR NITRIC ACID AND THE AMOUNT OF LEAD IN THE SUPERNATANT SOLUTION IS DETERMINED. THE FIRING DISTANCE ESTIMATES ARE MADE BY COMPARISON WITH DATA OBTAINED FROM TEST FIRINGS. (AUTHOR ABSTRACT)
