An analyst uses several different techniques to collect the evidence from the scene for later processing at a lab. Most blood spatter analysts begin with a certificate or degree in criminal justice, particularly forensic science. Specific classes include biology, anatomy, criminology, constitutional law, and statistical analysis. Once hired, analysts attend classes or workshops to continually update their skills and knowledge. Blood spatter analysts use math, physics, biology, and a knowledge of how blood behaves in certain conditions to help recreate the crime. Many bloodstain pattern analysts work in local and state crime laboratories that are associated with law enforcement agencies. Many agencies require blood spatter analysts to perform additional forensic science duties.
While this may be a description of a fictional TV character, blood spatter analysts can, in fact, determine how a crime took place, just by examining the bloodstains. However, it's not as easy as Dexter makes it out to be. But then, no real blood spatter analyst moonlights as an expert killer.
But even if you have seen countless television detectives rely on blood sprayed on the ceiling of a gory crime scene, there are probably a few things you do not know about the history and process of blood spatter analysis. Keep reading to learn more.
Whether you’re an up and coming forensic analyst or just someone who can’t get enough of CSI, chances are you have heard a thing or two about blood spatter analysis. This field involves using the physics of fluids to help to determine the events of a (usually) violent crime by analyzing the placement of the blood droplets at the crime scene.
