Will County State's Attorney Jim Glasgow says he'll go to trial against Drew Peterson even if his office loses an appeal to the Illinois Supreme Court.
Will County prosecutors want jurors to hear several hearsay statements they say link the former Bolingbrook police officer to the 2004 drowning of his third wife. A state appellate court ruled the statements were not admissible, and Glasgow's office announced an appeal on Friday.
The appeal was widely expected because the hearsay evidence is considered crucial in a case in which prosecutors have not revealed physical evidence linking Peterson to ex-wife Kathleen Savio's death.
Peterson is suspected in the 2007 disappearance of his fourth wife, Stacy Peterson, but he hasn't been charged.
Glasgow says a trial won't happen until sometime next year.
