Okla. Stat. tit. 57 § 513.2
The Department of Corrections shall notify the district attorney or requesting law enforcement agency of the sentencing county whenever an inmate completes his sentence or is otherwise discharged from the custody of the Department, except those discharged under the procedures and supervision of the Pardon and Parole Board. The notification shall be on a monthly basis and shall be made within ten (10) days following the month reported upon. The notification shall include the names of those inmates released under the provisions of the Oklahoma Prison Overcrowding Emergency Powers Act, Section 570 et seq. of this title. For the purposes of this section, "sentencing county" shall mean the county from which the inmate received the last sentence served prior to release but shall not refer to any sentences received which include inmate status as an element of the offense. Should the inmate be released from concurrent sentences then each sentencing county district attorney shall receive the notification. The district attorney shall disseminate the information provided herein to any and all law enforcement agencies deemed appropriate by the district attorney and to any victim of the crime for which the inmate was convicted. Notification shall be made to a victim by mailing the notification to the last-known address of the victim, if such information is requested by the victim. The district attorney shall not give the address of the inmate to any victim of the crime for which the inmate was convicted. The notifications required herein shall commence within ten (10) days following the first full month subsequent to the effective date of this act.
