The Scene Will Dictate What You Need From the Suspect
The primary objective of a crime scene investigator is to relate a suspect to the crime scene. In order to establish this connection, investigators must collect as much evidence as possible from both the scene and the suspect. The key point is that the scene will dictate what you need to obtain from the suspect. For example, if a pair of latex gloves is found at the scene, the inside of the gloves should be processed for prints, and then the suspect’s hands should be swabbed for traces of powder from those gloves (Warrington, 2009). In another situation where the victim was shot, the suspect’s hands should be tested for gunshot residue. However, this evidence is very fragile and can quickly degrade a few hours after the commission of the crime.
