A criminal case in Contra Costa begins when a prosecutor (District Attorney) files formal charges, a person is arrested, or a grand jury issues an indictment. In all criminal cases, the defendant (person accused of a crime) is presumed to be innocent. That means he or she may not be convicted of a crime unless proved guilty beyond a reasonable doubt. There are several courthouses around Contra Costa where a criminal case may be tried.
