JOLIET, Ill. (WLS) -- Drew Peterson, former Bolingbrook police sergeant and convicted killer, is expected in court Tuesday.
He is accused of trying to hire someone to kill Will County State's Attorney James Glasgow.
Peterson is already serving a 38-year sentence for the 2004 murder of his wife Kathleen Savio. Glasgow prosecuted the 2012 case.
The Savio case was reopened after Peterson's fourth wife, Stacy Peterson, disappeared in 2007.
Peterson is challenging wiretap evidence he said was improperly obtained. A pre-trial hearing for the murder-for-hire case was canceled last month due to flooding at the courthouse.
A decision on future court dates is expected during Tuesday's hearing.
