The Medical Forensics class have been learning about Blood Spatter Analysis the past weeks.

Bloodstain Pattern Analysis (BPA) is the study and analysis of bloodstains at a known or suspected crime scene with the purpose of drawing conclusions about the nature, timing and other details of the crime. It is one of the several specialties of forensic science.

Because blood behaves according to certain scientific principles, trained bloodstain pattern analysts can examine the blood evidence left behind and draw conclusions as to how the blood may have been shed. From what may appear to be a random distribution of bloodstains at a crime scene, analysts can categorize the stains by gathering information from spattering patterns, transfers, voids, and other marks that assist investigators in recreating the sequence of events that occurred after bloodshed. This form of physical evidence requires the analyst to recognize and interpret patterns to determine how those patterns were created.

The students have a lot of fun doing this section of the class. It is a great hands- on experience for all of them.
