Griffin has been charged with first-degree murder after an arrest warrant was first issued in April. Griffin was found after "America's Most Wanted" posted the story and got a tip on its Web site. Griffin was arrested in Oakland at a relative's house August 25. He was extradited to Illinois and charged over the weekend.
