Crime Scene Investigation

Crime Scene Investigation
All investigators are subject to being called to the scene of a crime twenty-four hours per day.  All supervisors and investigators are capable of thoroughly investigating a crime scene; however, oftentimes a second or third investigator may be called to assist and provide advanced expertise in a certain area of the investigation.  An investigator observes most autopsies involving questionable deaths and homicides.
