What Is Inmate Records In Rock County?

Inmate records in Rock County are official documents created and maintained by correctional facilities and law enforcement agencies to document individuals who are or have been held in custody within the county's detention system. These records are distinct from court records: the Wisconsin Court System maintains case files related to criminal proceedings, while the Rock County Sheriff's Office and its jail division maintain custody records that track an individual's physical detention status, movement, and conditions of confinement.

The record creation process begins at the moment of booking or intake, when a detained individual is formally processed into the facility. Records are continuously updated throughout the period of incarceration to reflect changes in custody status, housing assignments, disciplinary actions, and medical notations. Upon release, the record is closed and archived, though it remains subject to public records laws.

Under Wis. Stat. § 19.35, members of the public possess a right to inspect and copy records maintained by government agencies, including correctional facilities, subject to specific statutory exemptions. Custody records are further governed by provisions within Wisconsin's corrections statutes, which define the scope of information that must be documented during an individual's period of detention.
