Marengo County, Alabama, has about 19,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Marengo County Sheriff's Office, five city agencies and one other 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 District Attorney files charges, a case in the Marengo 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.

The Marengo County Sheriff's Office is the county agency that reports arrests to the FBI for Marengo County. It reported 31 arrests for 2025.
The FBI lists five cities in Marengo County with a reporting agency of their own, with the Census population and what each reported:

Booking: Where People Arrested in Marengo County Are Held
A person kept in custody after an arrest in Marengo 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 2019 the jail held about 39 people. Its rated capacity in 2019 was 120 beds, and it ran at 32 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 Marengo County
For Marengo County the place to look is the case index of the Marengo County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at marengo.alacourt.gov, phone (334) 295-2224).
Statewide, Alacourt is the statewide online index of Alabama trial court cases, sold by subscription.
Alabama does not let the public search another person's statewide criminal history. The record kept by the Alabama Law Enforcement Agency goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
