A well-placed source at FOX tells TMZ that reps for suspected wife killer Drew Peterson have contacted the producers of the new show "Moment of Truth," asking to hookup their client to a lie detector test on national television.

Peterson's wife Stacey has been missing and presumed dead since last October. Peterson's third wife, Kathleen Savio, was found dead in a bathtub in March 2004. At the time, her death was ruled accidental, but since Stacey's disappearance, Savio's body was exhumed for forensic examination and officials determined her death to be a "homicide staged to look like an accident." Stacey's family has continually asked Drew to submit to a lie detector test -- which he has repeatedly refused to do, until now.

Peterson denies any involvement in Stacey's disappearance, insisting she left him for another man.
