What is a Blood Spatter Analyst?


Blood spatter analysts (BSA) are a type of forensic science technician. A blood spatter analyst, also known as a bloodstain pattern analyst, is a professional trained to work with blood found at crime scenes.

Although a lot of their time is spent at crime scenes, they also spend an almost equal amount of time in labs analyzing the blood, and blood patterns and determining how they fit into the crime scene. The work performed by these professionals is very important because the patterns made by blood can determine many things, including what direction the blood came from, what angle it came from, and even the type of weapon used in the crime.

Independent Forensic Services states that a BSA can determine not only where the victim was killed but even if the victim was laying on a couch and struck by a blunt object or something similar. The blood pattern can also help law enforcement know how long the victim has been dead.
