Ohio Revised Code Title I. State Government § 109.86

(A) The attorney general shall investigate any activity the attorney general has reasonable cause to believe is in violation of section 2903.34 of the Revised Code. Upon written request of the governor, the general assembly, the auditor of state, or the director of health, job and family services, aging, mental health and addiction services, or developmental disabilities, the attorney general shall investigate any activity these persons believe is in violation of section 2903.34 of the Revised Code. If after an investigation the attorney general has probable cause to prosecute for the commission of a crime, the attorney general shall refer the evidence to the prosecuting attorney, director of law, or other similar chief legal officer having jurisdiction over the matter. If the prosecuting attorney decides to present the evidence to a grand jury, the prosecuting attorney shall notify the attorney general in writing of the decision within thirty days after referral of the matter and shall present the evidence prior to the discharge of the next regular grand jury. If the director of law or other chief legal officer decides to prosecute the case, the director or officer shall notify the attorney general in writing of the decision within thirty days and shall initiate prosecution within sixty days after the matter was referred to the director or officer.

(B) If the prosecuting attorney, director of law, or other chief legal officer fails to notify the attorney general or to present evidence or initiate prosecution in accordance with division (A) of this section, the attorney general may present the evidence to a regular grand jury drawn and impaneled pursuant to sections 2939.01 to 2939.24 of the Revised Code, or to a special grand jury drawn and impaneled pursuant to section 2939.17 of the Revised Code, or the attorney general may initiate and prosecute any action in any court or tribunal of competent jurisdiction in this state. The attorney general, and any assistant or special counsel designated by the attorney general, have all the powers of a prosecuting attorney, director of law, or other chief legal officer when proceeding under this section. Nothing in this section shall limit or prevent a prosecuting attorney, director of law, or other chief legal officer from investigating and prosecuting criminal activity committed against a resident or patient of a care facility.
