Who Issues Warrants in Arnold
In Missouri an arrest warrant is signed by a judge. For Arnold 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.

Who Serves Warrants in Arnold
The Jefferson County Sheriff's Office and the agency that reports for Arnold (filed by the FBI as Arnold Police Department) serve warrants in and around Arnold.
The FBI's agency list also places these agencies in Jefferson County: Jefferson College (campus police); the Dunklin R-5 School District (other agency); each serves warrants on its own ground.
The Eureka Police Department is listed by the FBI across two counties including Jefferson County, so its arrests are not broken out for Jefferson County here.

Each agency and what it reported is in Arnold arrest records.

How to Check for a Warrant in Arnold
The places to check for a warrant from Arnold:
- 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 Arnold
A warrant is recalled by the court that issued it, so clearing one from Arnold starts with the Circuit Clerk at (636) 797-6069: the case goes back on the calendar and the judge recalls the warrant when the person appears.
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.
