Kathleen Savio death and initial investigation
The death of Kathleen Savio in 2004 was the first pivotal event that drew sustained investigative and media attention. What began as a routine drowning call evolved into a major homicide inquiry after re-examination of evidence.
Basic facts and timeline
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Date of death | February 4, 2004 | Police report and court filings |
| Location | Suburban Chicago home in Bolingbrook, Illinois | Investigative records |
| Official cause at the time | Accidental drowning in a dry bathtub | Initial coroner report |
| Reclassification | Homicide in 2007 after reinvestigation | Prosecutor and autopsy review |
| Key investigators | Will County State’s Attorney office and lead investigator James Glasgow | Court transcripts and news accounts |
In 2007, prosecutors reclassified Savio’s death as a homicide, citing reassessed autopsy findings and concerns about the original investigation. This shift laid the groundwork for the later murder trial of Drew Peterson.
Stacy Peterson disappearance and its impact
In 2009, Stacy Peterson, Drew Peterson’s fourth wife, disappeared shortly after filing for divorce. Her case drew national attention and created intense scrutiny around Drew Peterson, though her body was never found and no charges directly tied to her disappearance were ever filed.
Core known details
- Disappearance date: October 28, 2009.
- Context: Shortly after serving divorce papers and cooperating with investigators about Kathleen Savio.
- Outcome: No arrest for Stacy Peterson’s disappearance; investigation remains open in some jurisdictions, but no charges were filed against Drew Peterson for her disappearance in a court of law.
The contrast between the evidentiary basis in the Savio case and the lack of a body or direct charges in the Peterson case shapes public understanding and ongoing speculation.
Trial, conviction, and sentencing for Kathleen Savio’s murder
The prosecution of Drew Peterson for Savio’s murder was marked by contentious pre-trial publicity, evidentiary disputes, and a high-profile trial that captivated national media. A 2012 conviction represented the only successful criminal outcome directly tied to the deaths.
Trial highlights and outcome
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Trial start | July 2012 | Court docket |
| Verdict | Guilty on first-degree murder charge | Court verdict |
| Sentence | 38 years in prison | Sentencing memorandum |
| Prison location | Stateville Correctional Center, Illinois (as of record checks) | Department of Corrections |
| Subsequent legal action | Conviction upheld on appeal as of published decisions | Appellate court rulings |
Peterson’s defense raised issues of investigative bias and marital strife, but the jury found the evidence—including statements, conduct, and law enforcement background—sufficient for a murder conviction. The sentence reflected the seriousness of the offense under Illinois law.
Civil cases and their broader consequences
In addition to criminal outcomes, Drew Peterson faced civil litigation that further shaped the narrative around responsibility and evidence. Civil cases can differ in burden of proof and result in financial liability even when criminal standards are not met.
Civil trial snapshot
- Plaintiff: Estate of Kathleen Savio.

These civil proceedings contributed to a lasting public perception of Drew Peterson’s legal entanglements and provided a separate venue for evaluating accountability.
Ongoing investigations, speculation, and durable questions
Years after conviction, questions remain about missing persons, investigative resources, and the completeness of public information. Some matters are settled; others are not.
