Peoria County Coroner Johnna Ingersoll said searchers had found no human remains as of 4:30 p.m., the Chicago Tribune reported. The operation was suspended about 6 p.m. and is not likely to continue Sunday but Illinois State Police Sgt. Tom Burek said it might resume Monday.
Stacy Peterson, the fourth wife of former Bolingbrook, Ill., police officer Drew Peterson has been missing since October 2007. He is awaiting trial in the 2004 drowning death of his third wife, Kathleen Savio, and is a suspect in the disappearance of Stacy Peterson.
Searchers were digging at a property owned by David Alwan, who said county, state and federal investigators were at his farm Friday, the Chicago Tribune reported Saturday.
"They had pretty solid leads with specific coordinates," Alwan said.
Celebrity news Web site TMZ reported Friday authorities received a tip from a prisoner who said Drew Peterson had described a place where Stacy Peterson's remains would be found. However, Will County sheriff's spokesman Pat Barry said police did not get a tip from an inmate and Drew Peterson's attorney, Joel Brodsky, said the former police officer "couldn't talk to somebody if he wanted to," the Chicago Sun-Times reported Saturday.
"I heard it's a friend of a friend of a friend -- there's nothing there," Brodsky said. "I think TMZ should stick to Angelina Jolie and Brad Pitt."
Pam Bosco, a spokeswoman for the family of Stacy Peterson, said, "We've just been told it's a very good lead and they're very hopeful," the Sun-Times reported.
