Drew Peterson's adult son says dad's no killer.
Stephen Peterson said Monday that the family is praying for his father's release from jail on last week's murder charge in the 2004 drowning of his third wife, Kathleen Savio.
Drew Peterson, a former police sergeant in Bolingbrook, Ill., is in custody on $20 million bail in Will County. He has denied any involvement in either Savio's death or the 2007 disappearance of his fourth wife, Stacy Peterson.
Stephen Peterson, a son from an earlier marriage, says in a statement that the family is confident of his father's innocence. He says Peterson's two children with Savio and two children with Stacy Peterson are staying with him.
