r on, Victor Balthazard together with his colleagues did research on blood spatter patterns, then gave their results to the scientific community later in 1939 (Rooker 1). Blood spatter was used to solve the State of Ohio v. Samuel Sheppard case in 1955. A blood spatter mechanism showed that Shepard did not kill his wife. Paul Kirk, a criminalist, gave blood spatter evidence that revealed another party present at the crime science other than the earlier identified ones. Through DNA tests conducted in 1998, Sam’s blood was removed from the collection of evidence. However, the most sought ideas on the interpretation of bloodstain were done by MacDonnell Herbert Leon. Most of his work took place in the 1970s and was supported by the Law Enforcement Assistance Administration (Rooker 1). Some of his relevant works are the publications on bloodstain interpretation and flight characteristics.
Blood spatter, and crime scene reconstruction topic is of interest to me because I want to learn more about how crimes are committed through using physical evidence and applying scientific methods to explain the events that surround the commission of these crimes. Through this knowledge, I can understand how to reconstruct crime scenes by conducting blood spatter analysis. At a crime scene, blood spatter functions as an indicator of the type of weapon that was used to cause injury. For instance, to determine if the injury was caused by a gunshot wound, one would determine the velocity of the blood spatter. High-velocity blood spatter often results from a gunshot wound (Wiid 21). Similarly, the type of bladder that comes from a blunt instrument, stab wound or dripping blood differs from that of a gunshot wound. Such information helps solve crimes that may otherwise go unsolved. There has been controversy within the criminal justice system about blood spa...
