A Preliminary Validation of the Use of 3D Scanning for Bloodstain Pattern Analysis
Abstract
3D scanning technology is beginning to be used more commonly to record crime scenes. Besides being able to document the scene and the locations of evidence within it, 3D scanners and associated software can now be used to analyze impact bloodstain patterns. In the present study, two “doubleblow” impact patterns were created in a classroom setting for analysis using both the HemoSpat bloodstain pattern analysis software and the FARO Focus3D scanner with FARO Scene software. Both methods produced area of origin results that were acceptably close to the actual initial blood source location.
Introduction
Impact bloodstain patterns, created when a blow is struck, can sometimes be analyzed to try to determine the approximate location of the source of the blood [1]. With this information in hand, an investigator can try to determine what might have occurred at the scene of the crime. Blood source areas of origin may indicate...
