Attorneys for Peterson asked the judge to bar mention of Stacy Peterson's disappearance during the upcoming trial for the 2004 murder of Kathleen Savio.
It was Stacy Peterson's disappearance that prompted investigators to exhume Savio's body. Her death was originally ruled an accident after Savio was found dead in a dry bathtub. Her death was later ruled a homicide.
Stacy Peterson reportedly made some of the disputed hearsay statements allowed into the trial by an Illinois appellate court.
