Criminal History Management Unit

The Criminal History Management Unit (CHMU) is responsible for creating, updating, and maintaining Oklahoma Criminal History records. Each record contains information that is used to make decisions about an individual in both the criminal justice community and in private industry.  Types of charges filed and the judgment of the courts is guided in large part by a person’s past arrest record. CHMU is also responsible for the sealing and expunging of criminal records as the result of court orders.

Hiring decisions, suitability, and qualifications of an individual for employment and licensing depend on the information contained in the record produced and maintained by CHMU. To ensure the accuracy of a criminal history record, each charge must have a corresponding fingerprint card to positively identify the individual arrested. The Identification Unit (ID) examines and compares fingerprint images to make positive identifications of these arrest records. These two units combine their efforts to build and maintain the state's criminal history records, ensuring the records are based on positive identification of the offender.

CHMU enters information into the Computerized Criminal History (CCH) program that electronically stores and produces Records of Arrest and Prosecution (RAP) sheets to be consumed by both criminal and non-criminal justice agencies. Juvenile records, pardons, deferred sentences, and expunged records must be properly recorded and documented within the record.
