William Balfour, the suspect in the Hudson family members, is refusing a polygraph test that the police wish to offer him.
A source close to the investigation said when detectives tried to issue it to Balfour, he immediately stopped cooperating and declined. If he's so innocent as he and his mother claim, then he has nothing to hide!
Balfour claims he's innocent, but officials still have not named anyone else in the case. So this guy is pretty much screwed. It's time to hang it up, Balfour.
