Inmates typically enter the system in one of four ways. Persons who are arrested for crimes in the western part of the county are typically brought to the local police substations first.
They are then transferred to a holding area adjacent to the District Court in Islip where they are processed and then arraigned. If committed to jail, the SCSO then transports the post-arraigned defendant to Riverhead, where they are admitted into the jail system.
Individuals arrested on the East end are first taken to local justice courts and then transported after arraignment to Riverhead. Probation/parole violators are typically brought directly to Riverhead to await revocation proceedings, unless they are arrested on new charges in which case they will enter the system just as any new arrestee would.
