Abstract:

Void patterns in bloodstain pattern analysis are often used to determine the absence or movement of an intermediate object from its original position during or after a bloodletting event. This article examines the use of void patterns as a method of estimating the area of origin of events that produce bloodstains. Employment of this method, which the authors have termed the Void Pattern Shadow Matching (VPSM) method, can help the analyst or investigator at the scene to quickly determine an approximate area of origin, which can later be confirmed by mathematical analysis.
