Blood Splatter Analysis

1313 words - 5 pages

Bloodstain pattern analysis (BPA), known in the criminal justice field as blood splatter analysis, has been studied since the 1890s. Blood splatter, or bloodstain pattern constructional readings, is a technique that seeks to piece together the incident that caused an individual’s bleeding. Understanding blood splatter on a wall or various surfaces can be instrumental in formulating if a crime was committed and if the blood discovered at the crime scene can be used as evidence. The first documentation of blood splatter research occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski . During Dr. Piotrowski’s research and documentation period, where he used live bunnies to research blood splatter from head wounds, he was left unnoticed in the profession of justice and was over shadowed by his primary works in math. Dr. Piotrowski’s research was first used in 1954 when a criminalist named Dr. Herbert MacDonell started training law-enforcement in blood splatter analysis and developed a program of study to continue to instruct analysts in 1971. In 1983 MacDonell founded the International Association of Bloodstain Pattern Analysts (IABPA). The extensive work of Dr. MacDonell in blood splatter analysis has now become a valuable asset used in crime-scene investigations.

The blood splatter pattern left at the crime scene can tell a trained examiner much about what crime might have been committed as well as rule out other sorts of offenses. Collectively with other indications, blood splatter can be very helpful in piecing together what took place, identify the victim, and attempt to identify who was to blame. The first task that a forensic scientist needs to accomplish when investigating a blood splatter is to authenticate that the substance is definitely blood. This can be determined by using a blood presumptive test that uses chemicals that change color in reaction to blood. This test is portable and may be done at the crime scene.
Once tests have determined the presence of blood, more will be completed in the lab to determine if the blood is animal or human. Other tests will determine the DNA, which can point the investigator to specific individuals. The completion of the actual splatter analysis is done by a forensic scientist who establishes the path of the blood and how it spread over the surface in question. The direction of movement can be determined by measuring the shape of the bloodstain on a surface. This will also show the approximate speed at which the blood contacted the surface, assists in distinguishing between the rapid movement of blood (produced by a gunshot, severing of a main artery), or slower movement of blood from a minor cut. The origination of blood can be determined by analyzing the size and location of the blood drops. A strong force of impact will cause the blood to break up into smaller drops. Blood splatter made up of larger drops with a path of smaller drops can show...
