St. Clair County, Michigan, has about 160,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from St. Clair County depends on where the incident happened: the St. Clair County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Michigan Freedom of Information Act requires of it.

Which Agency Holds a Report from St. Clair County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In St. Clair County that is the St. Clair County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the St. Clair County State Police in St. Clair County; a report taken on a state highway by it comes from that agency's own records office.
The Memphis Police Department and the Richmond Police Department are each listed by the FBI across several counties including St. Clair County, so their arrests are not broken out for St. Clair County here.
