George Marquez, District Attorney
The District Attorney, as a public prosecutor of both criminal and civil cases, ensures that justice is done and that the rights of all are safeguarded. The district attorney works with every component of the criminal justice system and the entire community, to protect the innocent, to convict and appropriately punish the guilty, and to protect the rights of victims and witnesses.
