You may know Dawn Kellner as the mother of Jared Kellner, the 15-year-old-boy who died on his way to Summerfest on June 24, 2010, when a 13 ½ ton concrete panel fell from the O'Donnell Park parking structure and crushed him. I know Dawn as a grieving mother who came to me to uncover the truth about why her son died so senselessly, and to make sure that those responsible are held fully accountable.
