The disappearance of the winter's ice afforded volunteers another opportunity to search a suburban pond on Wednesday for any clues that might help find Stacy Peterson.
Nothing was found.
Peterson's sister, Cassandra Cales, organized Wednesday's effort. Stacy Peterson disappeared in October 2007.
Authorities say her husband, former Bolingbrook police Sgt. Drew Peterson, is the prime suspect in her disappearance.
He's currently being help on $20 million bond in the death of his third wife, Kathleen Savio. A trial in that case will begin in two months.
