Repost: How Blood Pattern Analysis Works

Aside from what I’ve learnt from watching Dexter, I know very little about how useful Blood/Bloodstain Pattern Analysis (or BPA) can be to a criminal investigation.

BPA is the study of the pattern of blood left at a crime scene, in order to determine key details about the crime itself, weapon or victim. Blood stains are studied in terms of their size, length, height and location relative to other key aspects of a scene.

Blood can tell us a lot. For instance, did you know that you can tell the date and time that the crime occurred and whether the criminal was left or right-handed? Brilliant right?!

For you crime writing enthusiasts out there, or even those of you just interested in forensics, check out this ace infographic created by Forensic Nursing.
