Drew Peterson, 62, an Illinois ex-cop convicted of murdering his third wife after his fourth wife went missing, plotted to kill a prosecutor because Peterson was motivated by 'anger, hatred, revenge'. Peterson, allegedly told a fellow inmate he was willing to pay $10,000 for the killing of Will County State's Attorney James Glasgow. Peterson was convicted in 2012 of first-degree murder in the 2004 death of his ex-wife, Kathleen Savio. His fourth wife, Stacy Peterson, disappeared in 2007, prompting officials to reopen their investigation into Savio's death. Savio's body turned up in a dry bathtub in her home outside Chicago, but investigators determined she had drowned. At first, they said her death was an accident. Prosecutors said after Peterson was locked up, he recruited a prison informant known as 'Beast,' with whom he'd bonded over basketball and prison recipes. Peterson faces a sentence of up to 60 years if convicted of both solicitation of murder for hire along with solicitation of murder. He is serving 38 years for Savio's death.
