Kathleen Savio was married to Drew Peterson for eleven years before filing for divorce in 2003. The next year, she was found dead in her bathtub. Her drowning appeared to be an accident and for years, no one had reason to question it. But when Peterson's next wife, Stacy thirty years younger went missing, the tough-talking and wise-cracking former Illinois cop came under suspicion .
With Stacy Peterson missing and presumed dead authorities exhumed Kathleen Savio's body, looking for answers. A new autopsy pointed to homicide, and a 2002 letter was revealed in which Savio wrote that Drew, "knows how to manipulate the system, and his next step is to take my children away. Or kill me instead." He was arrested for Kathleen's murder, and is a prime suspect in Stacy's disappearance, Peterson continues to protest his innocence. New York Times bestselling author Carlton Smith digs deep into the mystery behind the two Peterson wives and sheds some light on one of the most complex crime cases in modern American history.
