Sheriff’s Office

The Office of the Sheriff

was instituted when the State of Iowa was granted Statehood in 1846. As the only elected law enforcement officer, the Office of Sheriff is unique in that the Sheriff is directly accountable to the people. The first Polk County Sheriff, Thomas Mitchell, took the Oath of Office on April 3, 1846. Our current Sheriff, Bill McCarthy, was reelected by the Citizens of Polk County in November 2016, and took the Oath of Office on January 3, 2017.

Mission Statement:

The mission of the Polk County Sheriff's Office is to preserve the integrity of the law through proactive community involvement, impartial enforcement, and secure custody of inmates. The Office will utilize advances in technology to detect and solve crimes and enhance public safety communications and will effectively use all available resources to protect and serve the public.
