What a blood splatter analyst does
A blood splatter analyst, also known as a bloodstain pattern analyst, examines the characteristics of bloodstains that include patterns of blood transfer, expiration and impact. They answer questions about the circumstances of a crime scene by applying concepts from biology (blood behavior), mathematics (geometry, angle and distance) and physics (velocity, capillary action and cohesion) to evaluate the blood evidence.
With so many variables involved, education and experience are crucial. A blood splatter analyst must utilize a combination of scientific observations, forensics education and professional experience to reach conclusions with minimal uncertainties. Advanced technologies like 3D modeling and digital imaging can provide additional objective perspectives during the interpretation process.
“Bloodstain pattern analysts are involved in reviewing criminal investigations involving blood-letting incidents. Within such a review, a bloodstain pattern analyst is tasked with conducting an unbiased analysis, with the ultimate goal of answering an ‘investigative question’ that may be posed by a prosecutor, detective, etc. These reviews include crime scene photographs, incident reports, medical reports, scan data and documentation data, etc.,” said Scott Swick, Texas Ranger, Texas Department of Public Safety and President of the International Association of Bloodstain Pattern Analysts.
Steps toward becoming a blood splatter analyst
Becoming a blood splatter analyst typically requires a formal college-level education, specialized training and crime scene experience. “A bloodstain pattern analyst should have a well-rounded and in-depth education. This includes degrees in physics, biology, mathematics or something similar, with basic and advanced bloodstain pattern training, fluid dynamics training, math and physics training, crime scene investigation training, bloodstain on fabrics training, etc.,” Swick said.
1. Earn a bachelor’s degree
A bachelor’s degree in forensic science, criminal justice or a natural science such as biology, chemistry or human anatomy is the most common and preferred educational requirement for a blood splatter analyst. As part of their education, some students complete internships to bridge the gap between education and application of their skills in the real world.
