Marathon, Florida, in Monroe County, has about 10,000 residents (2024 Census Bureau estimate). An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the State Attorney files charges, a case in the Monroe County Circuit Court. This guide says who keeps each one, what it costs and who may see it.
This guide covers who makes arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Marathon
The FBI lists no arrest reporting agency under the name of Marathon. In Monroe County the county agency that reports arrests is the Monroe County Sheriff's Office.
The FBI's agency list also places these agencies in Monroe County: the Highway Patrol in Monroe County (state police); the Department of Agriculture and Consumer Services, Office of Agricultural Law Enforcement at Monroe, the Department of Environmental Protection, Law Enforcement in Monroe County, the Department of Corrections, Office of the Inspector General in Monroe County, the Division of Alcoholic Beverages and Tobacco in Monroe County and one more (state agency).
Booking: Where People Arrested in Marathon Are Held
The county jail is where a person arrested in Marathon 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.
So far in 2026 the jail has held about 210 people on an average day, down from about 590 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 707 beds, and it ran at 63 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 Marathon
For Marathon the place to look is the State Attorney, which decides whether an arrest becomes a charge (its page is at sao19.org/other-offices, phone (850) 488-3070).
Florida is one of the states that lets anyone look up another person's statewide criminal history: anyone can run a name-based criminal history search online for $24, for $24 a search, through the Florida Department of Law Enforcement. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Marathon
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Florida Public Records Act (Chapter 119) the agency must answer promptly and in good faith; the statute sets no number of days, and it may charge the copy fees set by statute, plus a special service charge for large requests.

- A defendant who has been charged gets the report through the case: the State Attorney, (850) 488-3070, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
