Who does the prosecutor, or ADA (Assistant District Attorney) work for?
The Assistant District Attorney who prosecutes the case does not work for any of the witnesses or victims. The Assistant District Attorney works for the Commonwealth of Massachusetts. Every county in Massachusetts has its own District Attorney’s Office. The person in charge of each office is called the District Attorney, and is elected by the citizens of that county. The lawyers who work in the office are called Assistant District Attorneys, and are paid by the Commonwealth of Massachusetts.
