BOLINGBROOK, Ill., Nov. 25 (UPI) -- Illinois investigators are calling in the FBI to help search for missing 23-year-old Stacy Peterson.
The FBI will add more searchers and access to the "technical assistance of the U.S. Navy," Will County States Attorney spokesman Charles Pelkie was quoted as saying in Sunday's Chicago Tribune.
Emergency authorities and volunteers have been searching woods and various bodies of water, including the Bolingbrook Recreation and Aquatic Complex, since Peterson disappeared Oct. 28.
Former Bolingbrook Police Sgt. Drew Peterson has been named a suspect. His third wife, Kathleen Savio, was found dead in her bathtub in March 2004. Savio's death was ruled accidental at the time, but a recent autopsy showed evidence of homicide.
Drew Peterson has denied involvement in both cases.
