The Commonwealth’s Attorney’s Office prosecutes criminal offenses that occur in Gloucester County. Prosecutors in many states are called District Attorneys, Solicitors, and State's Attorneys. In Virginia, they are "Commonwealth's Attorneys." Each county and city in the Commonwealth of Virginia elects a Commonwealth's Attorney to prosecute criminal offenses that occur in that particular county or city.
There are two parties to a criminal case: the Commonwealth of Virginia and the person charged. In short, the Commonwealth accuses the defendant of committing a crime. Just as an accused has their own attorney, the Commonwealth has its attorney - the Commonwealth’s Attorney.
Common examples of criminal cases in which the Commonwealth’s Attorney’s Office participates are: homicide, rape, robbery, narcotics distribution, burglary, DUI and domestic violence.
