CHICAGO, Illinois (CNN) -- The decomposed body of a woman discovered in a Chicago, Illinois, industrial area is not that of Stacy Peterson, who disappeared October 28, Chicago police spokeswoman Monique Bond said Saturday.
An ambulance and police cars stand by near the location where a woman's body was found in Chicago Friday.
Police have said the woman appeared to have reddish-blond hair. An autopsy was to be done Saturday.
Illinois State Police have named Peterson's husband, ex-Bolingbrook Police Sgt. Drew Peterson, 53, a suspect in the disappearance of his wife, and have investigated whether he removed a blue plastic container from his home the night before his wife was reported missing.
Although the man who found the body reported seeing a blue barrel near the remains, Bond said Saturday that no such container was found.
An environmental surveyor from Lyons, Illinois, who was conducting tests at the industrial site in southwest Chicago found the body Friday afternoon. Police said he called his supervisors to report he'd seen what appeared to be a human foot and leg.
Drew Peterson has consistently denied any involvement in his wife's disappearance. He has said he believes she ran away with another man.
The body was found about 20 miles from the Petersons' home, where Drew Peterson said he last saw her, CNN's Susan Roesgen reported.
Drew and Stacy Peterson have been married four years and have two children. Drew has other children from a previous marriage.
Authorities are re-examining the death of Peterson's third wife, Kathleen Savio, who was found dead in a bathtub in 2004. E-mail to a friend
