Body in Des Plaines River Wasn't Peterson Or Stebic

Skeletal remains found a week ago along the Des Plaines are that of an unidentified man, Illinois State Police announced Wednesday.

There had been speculation the remains were that of Stacy Peterson or Lisa Stebic, two Will County women whose disappearances in 2007 captured national attention.

"An investigation to identify the remains is underway," a release from the ISP Forensic Crime Lab said.

There wasn't much of the person left -- just a ribcage, spinal column and thigh bones.  Coroner Patrick O'Neil said shreds of blue jeans and a small amount of cash were also found.

O'Neil said the search continues for the missing remains, and a forensic investigation is underway to whether the disarticulation came before or after death.

The coroner's office, O'Neil said, was given a conservative time frame in receiving forensic DNA and forensic anthropology results of approximately two weeks.

A preliminary estimation of how long the unidentified person has been deceased is approximately several months or more, O'Neil said in a statement.

Police continued to search the Des Plaines River on Thursday where the human remains were discovered in Channahon Township.

Stacy Peterson's husband, Drew Peterson, remains jailed on charges alleging he killed his third wife, Kathleen Savio, in 2004. Her death was initially ruled as an accidental drowning, but reclassified as a homicide after her body was exhumed and an autopsy conducted in October 2007 following Stacy Peterson's disappearance. Meanwhile, Drew Peterson cracked one-liners, making a phone call Wednesday morning from jail to a Chicago radio show.

Lisa Stebic's husband, Craig Stebic, has repeatedly denied any wrongdoing in connection with Lisa's disappearance, but he has been named by police as "a person of interest" in the investigation.
