Chuck Cox, father of Susan Powell, attends the trial of Susan's father-in-law, Steve Powell, during jury selection at the Pierce County Superior Court, in Tacoma, Wash., Monday, May 7, 2012. Powell, who is on facing charges of voyeurism and child pornography, is the father-in-law of missing Utah mother Susan Powell. Susan Powell is presumed dead, apparently at the hands of her husband, Josh Powell, who was Steve Powell's son. Josh Powell killed himself and the couple's two sons in a fiery explosion in February.
