It's been a decade since Drew Peterson's fourth wife, Stacy Ann Peterson, went missing without a trace — just three years after her husband's third wife, Kathleen Savio, was found dead in a waterless bathtub. Currently, the former police sergeant is serving 38 years in prison for the death of Savio, plus an additional 40 years after he was convicted in a murder-for-hire plot. So, what happened to Peterson following his 2012 guilty verdict?

The 63-year-old is incarcerated at the United States Penitentiary, Terre Haute in Indiana, a high-security prison. He was transferred there early last year after being charged with solicitation of murder and solicitation of murder for hire. From behind bars, Peterson had attempted to have Will County State's Attorney James Glasgow, who had been heavily involved in his case, killed.

According to the Chicago Tribune, Peterson was attacked by another inmate with a food tray in April 2017, but not seriously injured — though the incident resulted in him being separated from the general population. A few months before the attack, his son Stephen had said in an interview that his dad was in good spirits.

The Villa Park, IL, native filed a number of appeals in 2017 through his lawyers, but in September, the Illinois Supreme Court upheld his murder conviction. The father-of-six is eligible for parole in 2081.

In his interview with the Tribune, Stephen admitted that his dad "probably" killed Savio, and that he's come to believe the one-time officer also murdered Stacy, though says Peterson still maintains his innocence to him. "Over time, you hear enough (from police). They can't all be full of s–t," he reasoned. "I don't want to come out and say he did it … but, I'm sure he did it." The majority of his peers seem to agree.
