Drew Peterson offers $25,000 reward

Stacy Peterson disappeared in October 2007. She is Drew Peterson's fourth wife.

Drew Peterson insists Stacy told him she was planning to run off with another man. Her family believes she would never leave her children.

Investigators are treating the case as a possible homicide with Drew Peterson as a suspect. A grand jury is looking into Stacy's disappearance, as well as the death of Drew Peterson's ex-wife, Kathleen Savio.

Peterson denies wrongdoing in both cases.

Drew Peterson's $25,00 reward is for information that leads to the safe return of Stacy, according to attorney Joel Brodsky.
