Abstract:

The purpose of this study was to replicate the one performed in "Further Validation of the BackTrack Computer Program for Bloodstain Pattern Analysis - Precision and Accuracy" to validate the accuracy of the HemoSpat bloodstain analysis software against an accepted standard and to examine the reproducibility of the results. The Royal Canadian Mounted Police (RCMP) provided FORident Software the data for the 18 bloodstain targets from the original BackTrack study. The study of HemoSpat was initiated by FORident Software in October 2006, taken over by the RCMP in December 2006, and the analyses were completed in November 2007. The results show that the average distance from the known origin across patterns is in line with the original study. The standard deviations across patterns are well within the bounds laid out by the BackTrack study and shows that the results are reproducible given different analysts working with the same data.
