Question

a sample of physical evidence that is collected at a crime scene

Answer 1

Im not positive if this is the right answer but someone else looked into this with me and we kind of thought it would be Biological Evidence - Biological evidence includes blood, saliva, semen and other body fluid stains. Any
of this evidence may be important and should be collected. These stains should be accompanied by control
samples from unstained areas near the collected stains. A forensic light source (e.g. Polilight) may be of
assistance in locating these stains.
