JOLIET, Ill. (AP) - A judge says Drew Peterson's lawyers can hit at the credibility of Drew Peterson's vanished fourth wife as they defend the former Illinois police officer against charges he killed his third wife.
Judge Edward Burmila gave defense attorneys permission Wednesday to ask a witness if Stacy Peterson sought to extort her husband by threatening to tell police he killed Kathleen Savio.
Peterson has pleaded not guilty to murdering Savio in 2004. He was charged after Stacy Peterson disappeared in 2007.
Prosecutors presented hearsay evidence that Stacy Peterson implicated her husband in Savio's murder before she disappeared.
Stacy Peterson is presumed dead. And prosecutor Colleen Griffin argued the defense shouldn't be able to attack the credibility of someone who, in her words, Drew Peterson "made unavailable." He's denied any wrongdoing.
