Ohio Rev. Code § 321.43: Employment of night watchman.

If the county treasurer, county auditor, and probate judge notify the board of county commissioners, in writing, that, in their opinion, the safety of the public money in the county treasury requires it, the board shall immediately authorize the treasurer to employ a night watchman. The board shall fix the compensation of such watchman, to be paid in biweekly installments. The employment shall continue until the treasurer, auditor, and judge certify that it may be discontinued. This section does not affect the liability of the county treasurer or his sureties.
