Representatives for Drew Peterson - whose wife Stacey has been missing and presumed dead since October (and whose previous missus died under mysterious circumstances) - have reached out to the producers of Fox's Moment of Truth, asking that the suspected wife-killer be hooked up to a lie detector in front of a national audience, TMZ reports. Peterson all along has denied having any involvement in Stacey's disappearance, yet to date has refused requests from his in-laws to brave a polygraph. A Fox rep had no comment on TMZ's story.
