Stacy Peterson Missing: Illinois Cops, FBI Renew Search For Drew Peterson's 4th Wife (VIDEO)

Illinois State Police and FBI officials with search dogs, a helicopter and boat, combed through a wooded preserve Monday in hope of finding Stacy Peterson, the missing fourth wife of convicted murderer Drew Peterson.

Stacy Peterson, 23, disappeared in October, 2007, and her 58-year-old husband has been the sole suspect since then, according to Shorewood-il.patch.com.

Although Drew Peterson, a retired police sergeant, has never been charged with harming Stacy, he was convicted in September of murdering his previous wife, Kathleen Savio.

Monday's search is not believed to be linked to new information or specific tips and, according to WLS-TV, an Illinois State Police source said that they did not find a body.

In previous stories, Huffington Post reported that prosecutors suspect Peterson killed his pretty, sandy-haired fourth wife because she could finger him for Savio's death, Her body has never been found and no charges have ever been filed.

Jurors in Peterson's murder trial weren't supposed to link her disappearance to Savio's death, and prosecutors were prohibited from mentioning the subject during his trial.

Still, Stacy Peterson's family hoped a conviction in Savio's murder could lead to charges against Peterson in her disappearance.

Peterson, who is currently being held at the Will County Adult Detention Center in Joliet, Illinois, has said that his fourth wife ran off with another man and is still alive.
