What This Reference Covers
Contra Costa release information is split among different offices because release can mean bail, court order, sentence completion, transfer, alternative custody, probation, parole, or another agency handoff. The Sheriff holds county jail custody records for facilities such as Martinez Detention Facility, West County Detention Facility, Marsh Creek Detention Facility, and custody alternative programs. The California Department of Corrections and Rehabilitation handles state-prison records through CIRIS, while Contra Costa Superior Court records explain the case outcome behind many jail releases.
