An arrest warrant is an official, state-provided mandate, given to officers of the peace that directs them to apprehend the person named on the arrest warrant. Although arrest warrants always originate in the county in which the crime was committed, they are issued on behalf of the state. All arrest warrants must also be signed by a judge or a magistrate, and include the statutes and laws which were broken. Once issued, officers of the peace have 48 hours with which to apprehend the person indicated on the active warrant.
If you are concerned that there may be a warrant out for your arrest, then the place where you will want to begin your warrants search is through the McCulloch County Sheriffs Office. You can reach them by telephone at 325-597-2332, and in person at 300 W. Main Street, Brady, TX 76825. Most precincts will require you to appear in person to make an arrest warrant search request, however, so be prepared to visit the station.

If it turns out that you do have an outstanding warrant, it is best for you to simply turn yourself in as soon as possible. This is because, often, the courts will go easier on those they do not have to apprehend via an arrest. Although your warrant is active in a particular county in TX, state police officers can cross county lines, and apprehend you no matter where you are in Texas.
