Mission
To the people of Union County: you have the right to live your lives without becoming a victim of violence; to have your liberty, as well as the liberty of your neighbors, safeguarded; to own possessions knowing they will not be taken from you; to rest your head at night with the knowledge that should another transgress and cause harm to you, your family, or your property, such persons will be swiftly apprehended and brought to justice. Ensuring these rights is the most fundamental duty entrusted to government by those it governs and serves.
It is the mission of the Union County Prosecutor’s Office to allow the people of this County to live their lives without fear that those lives will be diminished by the acts of those who would betray the laws of a civilized society.
