Blood Residue (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In forensic science, blood residue - wet and dry remnants of blood, as well the discoloration of surfaces on which blood has been shed - can help investigators identify weapons, reconstruct a criminal action, and link suspects to the crime.Blood constitutes about eight percent of a person's weight (normally about five liters), and it circulates near the surface of the skin. Almost all trauma to the body, therefore, results in the shedding of blood. Its red color makes it readily apparent at crime scenes, and its residues are very difficult to completely remove. Blood residue has even been recovered from 100,000-year-old stone tools. Blood residue analysis is also an important technique in archeology.
