Who Makes Arrests in Herculaneum

The FBI's agency list also places these agencies in Jefferson County: Jefferson College (campus police); the Dunklin R-5 School District (other).

Booking: Where People Arrested in Herculaneum Are Held

The county jail is where a person arrested in Herculaneum 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 320 people. Its rated capacity in 2019 was 371 beds, and it ran at 86 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

A person sentenced to prison serves the sentence in a facility of the Missouri Department of Corrections, whose inmate locator is at web.mo.gov/doc/offSearchWeb.

Missouri is one of the states that lets anyone look up another person's statewide criminal history: the open record search on the MACHS site lets anyone check convictions by name, through the Missouri State Highway Patrol Criminal Justice Information Services Division. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
