A grand jury has broad powers to investigate a wide range of criminal offenses and to examine the performance of public officials and public institutions. Its deliberations are conducted in secret, in conjunction with the State Attorney or a designated Assistant State's Attorney. The grand jury consists of members who serve a two-month term of duty with the court. If there is sufficient evidence, person(s) indicted and charged with a crime will appear before a judge.
Grand jurors' names are selected from the same source list as petit jurors. They are paid on the same basis as trial jurors.
