Police Investigator I is a civilian classification that performs work of a quasi-police nature. Work requires considerable independence, initiative, and judgment in performing the duties of a specific functional area. Supervision is typically received from a sworn employee or a civilian supervisor who reviews work through direct observation, reports, meetings, and results achieved. The Police Investigator I is distinguished from the Police Investigator II’s and III’s by the latter's greater responsibility involved in investigating cases from the beginning to final disposition. Also, the Police Investigator I assignments involve more data entry duties than the other classifications. This class is FLSA nonexempt.
