Ohio
Cuyahoga County's Agency of Inspector General is the only Ohio body with explicit, statute-grounded oversight of a county sheriff — enabled by Cuyahoga's 2009-2011 home-rule charter, which uniquely converted the sheriff from an elected to an appointed officer. No other large Ohio county (Hamilton, Franklin, Summit, Lucas, Montgomery, Mahoning) has enacted a civilian oversight body covering its elected sheriff.
State context
Ohio's 88 counties elect their sheriffs, with Cuyahoga as the notable exception. The Cuyahoga AIG has charter-granted subpoena power, broad records access, and has conducted documented investigations of sheriff's-office operations (credit-card program, commissary operations, overtime). It is an ethics and integrity watchdog rather than a civilian review board for individual use-of-force complaints.
