Shiawassee County, Michigan, has about 68,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Shiawassee County Sheriff's Office, nine city agencies and one state agency. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the Prosecuting Attorney files charges, a case in the Shiawassee County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Booking: Where People Arrested in Shiawassee County Are Held
The county jail is where a person arrested in Shiawassee County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2019 the jail held about 120 people. Its rated capacity in 2019 was 120 beds, and it ran at 100 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
