According to the South Dakota Dept of Corrections Web Site, an Inmate Locator is not allowed based on conflicting state laws. "Some statutes require notification of victims of prisoner releases to parole, work release, minimum custody status, discharge, escape and furloughs while others restrict what information on inmates can be released." You can find out if an inmate is incarcerated in the South Dakota Prison system by calling the SD Central Records office. The phone numbers are 605-367-5190 or 605-367-5140. These phone numbers are ONLY for inmates that are in the state prison system and are NOT for local county and city jail systems.
