St. Clair County Sheriff Jail Roster
The St. Clair County Sheriff's Office operates the county jail in Port Huron. Under MCL 800.7, the sheriff has full charge and custody of the county jail. Sheriff Mat King oversees bookings, inmate housing, and all records for the St. Clair County jail. The jail holds pretrial detainees and those serving sentences of less than one year.
MCL 800.13 requires the sheriff to keep a record of each person committed to the jail. This includes the inmate's name, date and cause of commitment, which authority sent them, and the date of discharge. These booking records are part of the public file. Anyone can request them through Michigan's Freedom of Information Act. The St. Clair County jail handles arrests from local police departments, Michigan State Police, and the sheriff's own patrol units.

For state prison inmates who came through the St. Clair County jail, use OTIS from the Michigan Department of Corrections. OTIS covers state prisoners, parolees, and people on probation. It does not list county jail inmates. The ICHAT system from Michigan State Police gives criminal history records for $10 per search and covers arrests and convictions statewide.
St. Clair County Booking Records
When someone gets booked into the St. Clair County jail, staff create a record with the person's name, date of birth, physical description, and a booking photo. Charges are logged along with the arresting agency. Bond gets set by the court based on the charge and the defendant's history. All of this goes into the jail roster and becomes part of the public record.
Under MCL 15.233, you can request copies of jail records by sending a written FOIA request to the St. Clair County Sheriff's FOIA coordinator. The office has five business days to respond. MCL 15.234 limits fees to actual costs for copies and labor after the first $20 of search time. Booking photos are public records in Michigan. The court confirmed this in Patterson v. Allegan County Sheriff.
Some records may be exempt from disclosure. Under MCL 15.243, records that would interfere with active law enforcement investigations or compromise jail security can be withheld. But the basic booking information on the jail roster is public.
Note: The ACLU v. Calhoun County ruling in 2022 made clear that federal rules cannot block Michigan FOIA requests for jail records.
