Arrest warrants from Jackson County are issued when the magistrate can find probable cause against the accused through the affidavit filed by the cops along with their complaint. This document keeps information about the proof gathered in front of the bench. The purpose of this endeavor is to clearly show why the accused is being held responsible for the criminal act.
When the information in the writ is inadequate to show reasonable cause, the witnesses are called in. They narrate their version of what really transpired under oath. Their words are recorded in a written form and this is attached to the original directive that is handed to the police.
Once an active warrant from Jackson County is granted to the sheriff's deputies, they begin to actively pursue the accused. In fact, no time is wasted in making arrests under warrants because peace officers have to consider the very real risk of the accused leaving the county. Those detention directives that cannot be executed are saved in the law enforcement database as outstanding warrants.
