What Is Inmate Records In Lewis and Clark County?
Inmate records are official documents created and maintained by correctional facilities and law enforcement agencies to document the custody status, personal history, and legal circumstances of individuals held in detention. In Lewis and Clark County, these records are generated and managed by the Lewis and Clark County Detention Center, operating under the authority of the Lewis and Clark County Sheriff's Office. Inmate records are distinct from court records: while the First Judicial District Court maintains case files, dockets, and judicial orders, the detention facility maintains custody-specific documentation that tracks an individual's physical presence within the correctional system.
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 legal proceedings. Upon release, the record is closed and archived in accordance with applicable retention schedules. Under § 44-5-103 of the Montana Code Annotated, criminal justice information — including records of detention — is defined and governed as part of Montana's broader criminal justice information framework.
