When Stacy Peterson vanished without a trace, her husband, retired police sergeant Drew Peterson, steadfastly asserted his innocence and maintained that his wife, thirty years his junior, had run off with her lover. Months passed; exhaustive searches and clues turned up nothing; more questions than answers were raised about their marriage, about Stacy's vocal concerns for her safety, and about Drew Peterson's own bizarre behavior in the limelight as the number-one suspect in his wife's disappearance. Then came yet another shocking development, this time concerning his third wife Kathleen Savio. Three and one half years earlier, her suspicious death had been ruled an accidental drowning, but after a new autopsy it was now ruled as a homicide. A subject of intense media coverage and speculation, the case against Drew Peterson is still unraveling, but one haunting question remains- where on earth is Stacy?
