Police searching for Stacy Peterson again?

Chicago Sanitary and Ship Canal searched

ROMEOVILLE — The state police took to the water Wednesday in what a source said was a search for the remains of missing mom Stacy Peterson.

State police Sgt. Thomas Burek confirmed his agency had undertaken an operation on the Chicago Sanitary and Ship Canal, but would not say why.

"We did some searches," he said. "We're not commenting on what we're searching for."

But a source said she learned from an employee at a nearby business that state police said they were searching the canal as part of the Peterson probe.

Peterson vanished from her Bolingbrook home in October 2007. The state police consider her the victim of a "potential homicide" and have named her husband, Drew Peterson, their sole suspect in the case.

The state police have searched the canal before, beginning soon after Stacy's disappearance.

A police source said cell phone records placed Peterson near the canal only hours before Stacy was reported missing by her sister.
