To assure the utmost care in the collection and preservation of evidence at crime scenes, the Orland Park Police Department utilizes Evidence Technicians and Field Evidence Technicians. An Evidence Technician is a police officer, who is generally an investigator, who is trained in accepted methods of evidence collection, preservation and processing, and whose primary responsibility is to process a crime scene. A Field Evidence Technician is an experienced police officer who is trained in acceptable methods of evidence collection, preservation and processing, but, has primary responsibilities as a patrol officer. The use of Field Evidence Technicians allows the rapid response of an Evidence Technician to any crime scene which requires evidence processing.
