Archived: The Forensics of Blood (HS)
The examination of blood provides much information to crime scene investigators. Blood can provide information such as what type of blood it is (A, B, AB, or O) and can be further tested for DNA to determine exactly whose blood it is. Blood spatter patterns can give a Forensic scientist information about where the blood came from, if the victim was moving, what type of wound they suffered and more. Blood can also be collected and analyzed for information such as drugs ingested, if they had any poisons in their system and other toxicology information.
