In each case of pecuniary fine, an execution may issue for the fine and costs, though a capias pro fine was issued for the defendant; and a capias pro fine may issue for the defendant though an execution was issued against the defendant’s property. The execution shall be collected and returned as in civil actions. When the execution has been collected, the defendant shall be at once discharged; and whenever the fine and costs have been legally discharged in any way, the execution shall be returned satisfied.
