In a lot of organizations a criminal offense scene technician or a crime scene investigator are almost the very same. In some circumstances the technician is a pay and coaching stage grade under an investigator, But most agencies simply use possibly term to explain individuals people tasked with the obligation of locating, assessing and gathering actual physical proof from criminal offense scenes.
