The former Bolingbrook police officer is accused of killing his third wife, Kathleen Savio. Peterson is also a person of interest in the disappearance of his fourth wife, Stacey.
The judge will also meet with Illinois State Police to discuss what recently led them to search for Stacey's body in Peoria. He must decide if it is relevant to this case.
"If he finds it's relevant the state's going to be put to a position of one of two things. Either they can allow it to be released to us. Or if it's not released to us then they may have some trouble getting in evidence, certain evidence that may be relevant," said Joel Brodsky, Peterson's attorney.
Peterson's trial is scheduled to begin July 8th.
