Sheriff's Office Duties

The Office of Sheriff has been in existence since 1066.  Originally appointed by the English King, the "SHIRE REEVE" executed royal court orders and writs and was generally responsible for the capture of wrong-doers in their respective Shires.  The office evolved and eventually the title was shortened to "Sheriff".  The office was soon adopted by colonial governments.  As the colonies broke from English rule, Sheriffs became elected officials chosen by the people.  Although the Sheriff served as the chief law enforcement officer in the county, the sheriff's primary responsibility was to keep the peace and serve as an officer of the court.

Each of Each Missouri Sheriff provides county wide law enforcement and serves as officers of the court and keepers of the jail.
