Abstract

Nearly 40% of murders in the UK result from sharp force trauma caused by knives (Home Office 2012). Weapon-wound matching in Forensic anthropology attempts to estimate weapon class from the wound characteristics but few studies have investigated quantitative methods for performing this analysis on the microscopic scale. In this study five cadaveric pig torsos, prepared to mimic human anatomy, will be stabbed in the upright position with 12 different knives by two volunteers. Knife dynamics will be recorded using a Casio high-speed camera (1000fps), with wound tracts being recorded using photogrammetry. Samples will be defleshed exposing the regions on the ribs where the knives have made contact, thus marking the bone, so micro-CT can be performed. All samples will undergo a pre and post-stab CT. The analysis will be performed using various quantitative and qualitative methods to establish the feasibility of weapon-wound matching. Results are pending, however it’s hypothesized that, on the macroscopic scale, and individual bladed weapons have their own unique edge profiles which should leave unique striations on the bone for weapon-wound matching. If this is the case, and we can quantify this, then applications in forensic investigation for weapon-wound matching is a natural progression.
