The Michigan Criminal History and Your Own Copy
Michigan is one of the states that lets anyone look up another person's statewide criminal history: ICHAT lets anyone search public criminal history by name, for $10 a search, through the Michigan State Police. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Michigan State Police site.
Arrest Records Kept Locally in St. Clair County
The St. Clair County Sheriff's Office and the agencies that report for Port Huron, Marysville, St. Clair, Marine City, Capac and Yale keep the arrest records in St. Clair County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places one more agency in St. Clair County: the St. Clair County State Police (state police); it keeps the records of its own arrests.
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.
Together, the seven agencies in St. Clair County with all twelve months of 2025 on file reported 2,005 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in St. Clair County arrest records.
