State police and a forensic anthropologist excavated a site on the farm, but it turned up nothing. Investigators have not returned since, but say they're till looking into the tip that led them downstate.
“They’re researching all the avenues of the lead,” said Burek.
Burek says the department also experienced some setbacks with all the recent rainfall.
As far as resuming the search effort, Burek said Stacy Peterson vanished from her Bolingbrook home in October of 2007. Police call her husband, Drew Peterson, a person-of-interest in the case, but he is not charged with any wrongdoing.
Stacy Peterson’s disappearance sparked new interest in the death of Drew Peterson’s third wife, Kathleen Savio. Savio was found drowned in a bathtub in 2004. Drew Peterson now awaits trial on murder charges in that case. It is expected to begin July 8.
