One juror had a large gash across his forehead. Another wore dark glasses and a Band-Aid over her right cheek. As plaintiffs’ attorneys began their closing statements Tuesday in the largest class action against Ford Motor Co., it appeared the jury had been left battered and bruised after being bombarded for five months by dense and technical testimony.

But now the 12 jurors (and the one alternate hanging on) are facing a 16-page verdict form that could prove as challenging as some of the testimony they’ve heard since May.
