May 21, 2009— -- Police are facing major obstacles in identifying the body found along an Illinois river bank near the home of accused murderer Drew Peterson since the corpse is missing its head, arms and skin.

The office of Will County Coroner Patrick K. O'Neil said the body -- which many believe could be that of either Peterson's missing wife Stacy -- was clad in only women's underwear and shreds of blue jeans that held a small amount of money.

Since the corpse lacks a head, hands or feet, it has complicated identifying the body through dental records or prints.

"The partial skeletal remains consisted of a rib cage, spinal column and partial left and right femur bones," the coroner's office said.

The lack of skin has made it more difficult to obtain DNA. A coroner and a forensic anthropologist are working together to confirm the gender of the corpse and are expected to test the bone marrow to try and identify the remains, sources told ABC News affiliate WLS's Amy Jacobson.

The coroner's office said it will take at least two weeks to obtain the DNA and determine its match.

They are also trying to determine whether the head was severed before or after death, O'Neil said. Police are also searching for the body's head and other body parts.

Though officials acknowledge the body could be someone else's the similarities between Stacy Peterson and another missing woman, Lisa Stebic, are numerous. Both are of similar height and weight and both have had Cesearan sections after giving birth. They also disappeared within months of each other.

The discovery Wednesday of the decomposing body near Peterson's Illinois home has the potential to blow huge holes in his claim that his fourth wife simply ran off with another man.

Peterson, a former police sergeant, sits in jail on charges he murdered his third wife, Kathleen Savio.

But Stacy Peterson wasn't the only local woman who disappeared in 2007. Lisa Stebic, a mother from nearby Plainfield, Ill., disappeared in April 2007.

"My honest feeling is hope the body is ID'd if it was Lisa or Stacy," Stebic's cousin Melanie Greenburg said. "I hope one of our families gets closure from this."

But the fact that the decomposing body was found less than a mile from a blue barrel could be significant, as Peterson's stepbrother told "Good Morning America" in March that he helped Peterson move a heavy blue barrel from the Petersons' home into their SUV shortly after Stacy Peterson disappeared.

"I know he killed Stacy," said Peterson's stepbrother Thomas Morphey.

Area resident Michelle Williams spotted the blue barrel in the river earlier this week and notified police.

"A blue barrel in the river is something people would want to know about, especially police," Williams said. "When we first saw the blue barrel we first thought of Stacy Peterson."

Drew Peterson has denied any involvement in Savio's death and Stacy Peterson's disappearance, even as the majority of public opinion remains suspicious. Peterson has pleaded not guilty to first-degree murder charges in the death of Savio, whose body was found in her empty bathtub with a gash in the back of her head. He remains jailed on $20 million bond.

Investigators say the partial remains of a small woman clad only in underwear were found by a barge clean-up crew on the bank of the Des Plaines River near rural Channahon, Ill.

The Will County coroner's office said it will conduct an autopsy today and investigators say DNA will be crucial in identifying the body.

"If it isn't Stacy today," Peterson neighbor Sharon Bychowski said," we'll keep looking for her."
