Overview

Kathleen Savio, a 40-year-old divorced mother of two who was studying to be a nurse, was found face down in the dry bathtub of her Bolingbrook, Illinois home on March 1, 2004, with a gash on the back of her head. She had divorced Drew Peterson, a Bolingbrook police sergeant, about five months earlier; a hearing to divide their assets, including part of his pension, was weeks away, and in 2002 she had written in an order of protection that she feared he could kill her. A coroner's jury that included a police officer who vouched for Peterson ruled the death an accidental drowning. In October 2007 Peterson's fourth wife, Stacy, 23, vanished and he became the suspect. Will County State's Attorney James Glasgow reopened the Savio case, convened a special grand jury and had her body exhumed in November 2007. A second autopsy found she had drowned after a beating, and on February 21, 2008 her death was reclassified as a homicide. Illinois passed a hearsay law written with the case in mind, and Peterson was indicted and arrested on May 7, 2009. With no physical evidence and no eyewitness, prosecutors relied on what Kathleen had told her sister, a classmate and the authorities, and what Stacy had told her pastor and a divorce lawyer. A jury convicted Peterson of first-degree murder on September 6, 2012; he was sentenced to 38 years, later drew 40 more for trying to have Glasgow killed, and lost his appeal in the Illinois Supreme Court in 2017. Stacy Peterson has never been found.

How it was solved

Nothing new was found at the scene. What changed was who was looking, and why. In 2004 a six-member coroner's jury took thirty to forty-five minutes to call Kathleen Savio's death an accident. One juror said later that a police officer on the panel vouched for Peterson, that the lay jurors could not explain the bruises, and that there was no option of undetermined. On October 28, 2007 Stacy Peterson was last seen. A state police captain called her husband clearly a suspect, and within days Will County State's Attorney James Glasgow reopened the Savio file, convened a special grand jury and petitioned to exhume her body, arguing that the evidence was consistent with the staging of an accident to conceal a homicide and that a one-inch gash would not have knocked her out. Her body was exhumed on November 13, 2007. The forensic pathologist retained by the state's attorney concluded she drowned and that her death was a homicide; a nationally known pathologist examining the body for her family found fresh bruises on both sides of the body and a scalp laceration that could not have come from one fall. Glasgow announced the reclassification on February 21, 2008. Because no physical evidence tied Peterson to the bathroom and nobody saw him there, the case rested on what the two women had said while alive: Kathleen's 2002 order of protection and her statements to her sister and a nursing classmate that Drew had said he would kill her and that she would never get his pension or her children; Stacy's account to her pastor of Drew coming home late, dressed in black and carrying a bag of women's clothes, around the time of the death, and her statement to a divorce lawyer that he had killed Savio. Illinois passed a hearsay law in 2008 to let such statements in. A grand jury indicted Peterson on May 7, 2009. After a 2010 hearing the trial judge admitted five of thirteen statements; in April 2012 an appellate court reversed him and allowed more. At trial a former co-worker testified that Peterson had offered him $25,000 to find someone to kill Savio. Jurors said the sheer number of witnesses convinced them, along with the divorce lawyer the defense itself had called. On September 21, 2017 the Illinois Supreme Court unanimously upheld the use of the hearsay under the doctrine of forfeiture by wrongdoing.
