The primary function of the office is to investigate and prosecute felony, misdemeanor, traffic, and juvenile criminal cases in concert with local and federal law enforcement agencies, as well as complaints from private citizens.
The Commonwealth's Attorney handles the Loudoun County Victim Witness Program which interfaces between the judicial system and crime victims and witnesses to help ensure victim and witness cooperation in prosecution, increased witness safety, and reduced levels of trauma often associated with criminal cases.
