(AP Photo/M. Spencer Green, File) (Newser) – After five years of headlines, the Drew Peterson murder case has come to a verdict: The former Chicago-area police officer is guilty of killing Kathleen Savio, his third wife, the jury says. His maximum sentence would be 60 years. It's a victory for a prosecution that based its arguments on hearsay and circumstantial evidence, the AP notes. Peterson also remains a suspect in the disappearance of his fourth wife, Stacy Peterson. "I knew it," Savio's brother-in-law told the Chicago Tribune. "Now I can go out there and say he's a murdering bastard. You can print that. You can put it in a headline." Earlier today, the jury asked the judge what "unanimous" meant, which one lawyer thought pointed to a "not guilty" verdict, NBC Chicago reports.
