Alger County, Michigan, has about 8,700 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Alger County Sheriff's Office, one city agency 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 Alger 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.

Who Makes Arrests in Alger County
The Alger County Sheriff's Office is the county agency that reports arrests to the FBI for Alger County. It reported 39 arrests for 2025.
One city in Alger County reports its arrests to the FBI separately:
- Munising, 1,948 residents: 31 arrests reported for 2025.

The FBI's agency list also places one more agency in Alger County: the Alger County State Police (state police).
How Many Arrests Each Agency Reports in Alger County
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Alger County Sheriff's Office: 39 for 2025, 33 for 2024, 51 for 2023, 45 for 2022, 43 for 2021 and 52 for 2020.

Together, the two agencies with all twelve months of 2025 on file reported 70 arrests that year. The same agencies with both 2025 and 2024 complete reported 70 in 2025 against 55 in 2024, up 27 percent.
Through April 2026, the two agencies with every month so far on file reported 28 arrests, against 22 in the same months of 2025.
Booking: Where People Arrested in Alger County Are Held
A person kept in custody after an arrest in Alger County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2020 the jail held about 26 people, down from about 35 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 50 beds, and it ran at 70 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Alger County

Statewide, MiCOURT Case Search is the Michigan courts' statewide case search; not every court has joined.
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. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
