Bloodstain pattern analysis is a field of forensic science which has been evolving for several years. As with any discipline, keeping current is very important. FORident Software's HemoSpat brings the crime scene analyst the latest in bloodstain pattern analysis software.
Performing the directional analysis of projected stains at a bloodletting scene can provide the bloodstain pattern analyst with crucial information. Consider the current methods:
- Physical stringing at the crime scene - requires the use of disposable resources, is time and labour intensive, and depends a great deal on the crime scene analyst's diligence and experience.
- Mathematical methods - time consuming and leaves a lot of room for mistakes in the analyst's calculations. The analyst may not use enough stains due to time constraints or computational complexity.
- BackTrack software - forces the analyst to follow specific steps which makes it difficult and time consuming to correct mistakes or allow others to review your work. BackTrack does not allow you to use angled surfaces and has problems with current digital image sizes.
HemoSpat provides the analyst an efficient method of computing the 'strings' and the area of origin for a bloodstain pattern from a crime scene. This data may be used to provide a 3D representation of an impact pattern or for input into crime scene reconstruction software.
Bloodstain pattern analysis follows scientific principles - the analytical methods are specific, robust, reproducible, and reliable. HemoSpat maintains the analytical data from each project making peer review and verification possible.
Software should be simple to use. Its purpose is to help you get your analysis done more efficiently and more accurately.
With HemoSpat, the focus is on you, the bloodstain analyst, and how you want to work. We have created HemoSpat to provide the international bloodstain pattern analysis community with solid, efficient, and easy-to-use software.

News: IABPA Conference 2009 - Portland, Oregon, USA
Friday, October 16 2009 @ 03:51 PM EDT
Last week I attended the IABPA conference in Portland, Oregon and it was quite a busy one for me. The organizers and hosts from the Oregon State Police - Pam Bordner, Nici Vance, John Amish, Dan Alessi, and others [I know I missed some...] did a great job.
I had the opportunity to present two 2-hour workshops on HemoSpat and I think they went quite well. It was the first time I'd presented them, so I ended up having too much material and was a bit rushed, but overall I think the attendees got a good feel for the software. I'll know better for next time how to set things up time-wise. I have to thank Jason the IT guy for setting up all the computers and projector, as well as installing additional software.
The conference was also a great chance to interact with some of my clients and very valuable for direct feedback from people such as Norm Reeves [BPA Consulting], Ross Gardner [Bevel, Gardner, & Associates], Michael Maloney [Bevel, Gardner, & Associates], Silke Brodbeck [Blutspureninstitut], Ken Jones [Portland Police Bureau], Ray Kusumi [Washington State Patrol], Elizabeth Toomer [Naval Criminal Investigative Service (NCIS)], and Kiyomi Griffey [Naval Criminal Investigative Service (NCIS)].
Some of the talk highlights for me were the exchanges about the Phil Spector case by Lynne Herold [L.A. County Sheriff's Department], Stuart James [James and Associates Forensic Consultants, Inc.], and Jim Pex [Pex Forensic Consulting, Inc.], the case presentation by Mark Reynolds [Western Australia Police] on the Andrew Mallard case, Paul Kish's [Forensic Consultant & Associates] talk about preparing for expert testimony, and Scott Hlady's [Ontario Provincial Police] talk about conducting BPA investigations in remote communities.
All-in-all a very good conference and as usual it was great to see old friends and make new ones. I look forward to seeing everyone in Lisbon, Portugal and Atlantic City, New Jersey, USA in 2010!

We look forward to hearing any feedback from you!

Technical Papers: HemoSpat Validation
Sunday, August 16 2009 @ 04:37 PM EDT
FORident Software, in conjunction with the Royal Canadian Mounted Police, coordinated a validation study of HemoSpat in 2006-2007. The study used the same data which was used for the paper Further Validation of the BackTrack Computer Program for Bloodstain Pattern Analysis - Precision and Accuracy by Carter et al. published in the IABPA News in September 2005. Using the same data allows us the examine of accuracy and reproducibility using HemoSpat with respect to an accepted standard.

News: Phasing Out Support For Mac OS X 10.4 and Windows 2000
Friday, August 14 2009 @ 05:38 PM EDT
With the impeding arrival of both Mac OS 10.6 and Windows 7, we have decided to begin phasing out support for Mac OS X 10.4 and Windows 2000. So, as of version 1.3 of HemoSpat - to be released Q4 this year - Mac OS X 10.4 and Windows 2000 will not be supported. [Note: HemoSpat v1.3 may actually still run on Windows 2000, we just won't be supporting it. It definitely will not run on Mac OS X 10.4.]
The reason for this is for each release of HemoSpat we have to test across all versions of the OSes we are supporting. Currently that includes Mac OS X 10.4 PPC, Mac OS 10.4 Intel, Mac OS 10.5 Intel, Windows 2000, Windows XP, and Windows Vista. When we eventually add Mac OS 10.6 and Windows 7, the testing time for each release goes through the roof! Phasing out the older versions will allow us to focus our work on the main product.
