A jury has found manufacturer Advance Cast Stone mainly responsible for the collapse of a Milwaukee, Wis., parking garage panel that killed a teenager and injured two others in 2010 and awarded $39 million in damages. The civil jury also found that Advance Cast Stone intentionally concealed and misrepresented a defect or deficiency in its installation of concrete panels at the Milwaukee County-owned O’Donnell Park parking garage. Fifteen-year-old Jared Kellner was killed when one of the 13-ton panels fell, and two others were injured: Amy Wosinski and her son Eric, who was 15.
