FILE - In this undated file photo provided by the Stacy Peterson family, Stacy Peterson, 23, right, of Bolingbrook, Ill., is seen with her younger sister Cassandra Cales. Peterson, the wife of Drew Peterson, a sergeant with the Bolingbrook Police Department, was reported missing Oct. 29, 2007. On Tuesday, July 31, 2012, opening statements are slated in the much-anticipated trial of the 58-year-old Peterson, who was charged with the 2004 murder of his 40-year-old third wife, Kathleen Savio, only after his fourth wife, Stacy Peterson, vanished without a trace in 2007. Many Savio family members are potential witnesses and so can't speak publicly about the case or sit in on testimony. But Cales, one of the most outspoken members of Stacy Peterson's family, said she will be at the Will County courtroom as the trial starts in earnest.
