The coroner and police reports from the 2004 death of Kathy Savio raise many questions about how the original investigation was handled, report Erika Slife and Matthew Walberg of the Chicago Tribune. "The investigators and experts re-examining her death as a possible murder are now asking how police could have been so quick to overlook signs that something sinister may have happened to the third wife of Drew Peterson, then a sergeant for the Bolingbrook Police Department." The Tribune's review of of the reports reveal information that calls into question why the police were so quick to dismiss the potential of foul play. The investigation was reopened after Peterson's fourth wife disappeared in late 2007. Savio's death is being pursued as a murder investigation following a second autopsy indicating her cause of death as homicide.
