grand jury witness

A grand jury witness is someone who provides testimony or evidence to a grand jury, which is a group of citizens convened to investigate potential criminal activity. Unlike a trial jury, a grand jury does not determine guilt or innocence but assesses whether there is enough evidence for a criminal charge to be filed. Witnesses can include victims, experts, or anyone with relevant information. Their testimony helps the grand jury decide if there is probable cause to believe a crime has occurred and whether to proceed with formal charges against a suspect.
