Who Issues Warrants in Herculaneum
In Missouri an arrest warrant is signed by a judge. For Herculaneum that means the Jefferson County Circuit Court, which hears every civil, criminal, family, probate and juvenile case, with associate circuit judges taking misdemeanors, traffic and small claims. A city with a municipal divisions of its own issues warrants on the tickets and ordinance cases it tries.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the Circuit Clerk keeps that file.

Together, the six agencies in Jefferson County with all twelve months of 2025 on file reported 2,576 arrests to the FBI that year; arrests on warrants are counted among them, not separately.

How to Check for a Warrant in Herculaneum
Whether a warrant is out from Herculaneum shows in three places:
- The court file of the case, through the Circuit Clerk at (636) 797-6069, since a warrant is recorded in the case it was issued in.
- Case.net, the Missouri courts' free statewide case search, for a case whose register of actions shows a warrant.
- The Prosecuting Attorney, phone 636-797-5321, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Jefferson County pages SearchSystems verified (the sheriff's, the court's, the prosecutor's and the records request page) is a list of open warrants, so a check means asking the court or the prosecutor about a case by name.
Clearing a Warrant from Herculaneum
Only the judge who issued a warrant can recall it. For a case from Herculaneum that means appearing before the Jefferson County Circuit Court, with the case put back on the calendar through the Circuit Clerk.
A lawyer can often arrange the appearance in advance. The Prosecuting Attorney's page SearchSystems verified is at jeffcomo.gov/230/Prosecuting-Attorney, phone 636-797-5321.
