Bloodshed events are physically evidenced by stains at the scene, whether visibly apparent or not. Identifiable stains can be detected through various means, examined, quantified, classified and documented to reveal how events may have occurred. While serology can identify ‘who’, bloodstain pattern analysis (BPA) tells us ‘how’.
BPA informs my criminal behavioral analysis approach, setting me apart from other analysts. Based on physical, mathematical and biochemical properties in accordance with the scientific method, BPA can reveal information pivotal to realistic crime scene reconstruction. Angles of impact can sequence bloodshed events to determine actor’s location(s), effectively ruling out impossible scenarios.
Analytical results with corresponding photographic images offer convincing, cogent and concise scientific evidence for courtroom presentation. My biomedical background e.g., human anatomy/physiology, neurochemistry, etc. means that I can effectively liaise with medical examiners.
