Whenever a prosecutorial official, after the investigation of the cause and circumstances of a person’s death, declines to criminally prosecute any person in connection with such death, a member of such deceased person’s immediate family may file a written complaint with the Chief State’s Attorney or the Criminal Justice Commission. Not later than thirty days after the receipt of such complaint, the Chief State’s Attorney or the chairperson of the Criminal Justice Commission shall respond in writing to the complainant informing the complainant of the action, if any, said Chief State’s Attorney or chairperson has taken or intends to take concerning such matter.
