Problem
If you recall from Unit III, the police were called to investigate the scene of a death in which a mother reported that she had found her teenage son dead on the floor in his bedroom. There was a large pool of blood on the carpet near the son's head and possible signs of a struggle. These signs include scratches on the victim's body, torn clothing, clumps of the victim's hair and some unidentified hair on the floor, and a nightstand laying on its side with a broken lamp next to it. In addition, some drug paraphernalia is discovered inside the victim's nightstand.
Describe which of the various tools and techniques that we discussed in this unit would be needed to process and analyze the physical evidence found at the scene.
