Connecticut - - Where do criminal justice data live in your state?


Conviction information is public record, from most agencies who hold it. Nonconviction information is more tightly regulated, though there are avenues of access for research or other purposes, but conflicting statues may impede understanding and access.

Where do criminal justice data live in your state?

Criminal History Data

The Connecticut Department of Emergency Services and Public Protection (DESPP)’s Division of State Police, Bureau of Identification (SPBI) maintains the state’s Computerized Criminal History (CCH) System. Additionally, the State Police oversee the offender-based tracking system (OBTS), Connecticut’s suprasystem, designed to bring together several automated data systems maintained by agencies across the state. The OBTS is designed for access by criminal justice officials and allows these agencies to trace adults through the criminal justice process. Examples of the information found in the OBTS include individual profiles and classifications, arrest data, and court case history and status information.

Court Data

The Connecticut Judicial Branch maintains information related to all superior court cases resulting in conviction in their Case Management Information System (CMIS).

Corrections Data

The Connecticut Department of Correction (DOC) maintains the Offender Based Information System (OBIS), which contains information concerning people incarcerated by the DOC. Since all county jails and state prisons fall under the umbrella of the DOC, the OBIS contains data on individuals who have been sentenced to confinement, as well as those who have not been convicted of a crime but are being held pre-trial. The OBIS excludes information on juvenile offenders and those individuals held on behalf of the U.S. Immigration and Customs Enforcement.

Other Known Data Sources

Connecticut is one of few states with a unified prosecutorial system. Here State’s Attorneys, overseen by the Office of the Chief State’s Attorney, represent each of the thirteen judicial districts. While there is currently no known data collection standardization across these offices, recent legislation (i.e., Senate Bill 880, “An Act Increasing Fairness and Transparency in the Criminal Justice System”) requires the state’s Division of Criminal Justice to report annual prosecutor data beginning February 2021. In addition to these statewide criminal justice systems, each local county- or city-level agency maintains its own information. While the state moved to abolish the elected sheriff system in 2000, each of Connecticut’s eight counties is represented by a number of state marshalls, who act as sworn peace officers in the county. In addition, as of 2008, there were 120 local police departments throughout Connecticut, each employing at least one full-time officer and its own arrest data to some extent.
