Lawyers for Drew Peterson have asked the Illinois Supreme Court to toss out his conviction for the murder of his third wife.
An Illinois appellate court in November affirmed the former Bolingbrook police officer's murder conviction and sentence in the 2004 death of Kathleen Savio, whose body was found in her suburban Chicago home's bathtub. The court upheld Peterson's 38-year sentence, meaning he won't be paroled until 2047.
In their appeal filed Tuesday, Peterson's lawyers argue he was denied a fair trial due to the use of so-called hearsay statements, as well as other alleged critical errors, during court proceedings in Will County.
Peterson is scheduled to stand trial on charges he solicited an inmate to kill Will County State's Attorney James Glasgow, who prosecuted the Savio case.
