How to report someone that has a warrant for their arrest?

Contact the Sheriff's Department (not the police department) for the COUNTY in which the person is residing and alert them to the person's current location, the county which issued the warrant and the person's name or other identifying information. If the warrant is for a felony or serious misdemeanor, the Sheriff's Department will take it more seriously. If you are reporting them for a lessor offense and the person is outside the county in which the warrant was issued, you may not get any response.
