Joel Bohy, who is director of historic arms and militaria at Bruneau Auctions by day, spends his off hours helping apply forensic and ballistics research to historical conflict sites. He shared some of his recent work with Antiques and The Arts Weekly following a recent lecture he presented on the topic at the Sharon Historical Society.
