(J) A law enforcement agency shall investigate each report of abuse or neglect it receives under this section. In addition, the department, in cooperation with law enforcement officials, shall investigate each report regarding a resident of a facility operated by the department to determine the circumstances surrounding the injury, the cause of the injury, and the person responsible. The investigation shall be in accordance with the memorandum of understanding prepared under section
5126.058 of the Revised Code. The department shall determine, with the registry office which shall be maintained by the department, whether prior reports have been made concerning an adult with a developmental disability or other principals in the case. If the department finds that the report involves action or inaction that may constitute a crime under federal law or the law of this state, it shall submit a report of its investigation, in writing, to the law enforcement agency. If the individual with a developmental disability is an adult, with the consent of the adult, the department shall provide such protective services as are necessary to protect the adult. The law enforcement agency shall make a written report of its findings to the department.
If the individual with a developmental disability is an adult and is not a resident of a facility operated by the department, the county board of developmental disabilities shall review the report of abuse or neglect in accordance with sections 5126.30 to 5126.33 of the Revised Code and the law enforcement agency shall make the written report of its findings to the county board.
