A possible key witness in the Drew Peterson investigation has reportedly been given immunity. Will County State's Attorney James Glasgow approved the immunity for Peterson's stepbrother, Thomas Morphey, shortly after Stacy Peterson, Drew Peterson's fourth wife, disappeared in October of 2007.

But the Herald News reports Morphey has not gone before the grand jury. The paper reports that Morphey may have unwittingly acted as Peterson's accomplice when he helped haul away a blue barrel out of Peterson's home.

The paper says Morphey overdosed on sleeping pills after learning Stacy vanished and fears he had something to do with it.

Drew Peterson is a suspect in Stacy's disappearance but has not been charged with any wrongdoing. He contends that Stacy simply left him.
