On request, a correctional officer may have expunged from any file the record of a formal complaint made against the correctional officer if: the Intelligence and Investigative Division that investigated the complaint: exonerated the correctional officer of all charges in the complaint; or determined that the charges were unsustained or unfounded; or a hearing board acquitted the correctional officer, dismissed the action, or made a finding of not guilty. There is no time requirement for expungement under paragraph (1) of this subsection.
