Ill. law allowing hearsay to shape Peterson case

Ill. law allowing hearsay to shape Peterson case: "Drew Peterson's third wife will have a chance to 'testify from the grave' under an Illinois law passed amid the media frenzy over his missing fourth wife, but some say prosecutors could be on shaky legal ground if they plan to build their murder case around that testimony. Peterson appeared in court Friday, the day after he was charged with killing Kathleen Savio, his third wife who was found dead in a dry bathtub in 2004 with a gash on the back of her head."
