Gary Coleman's ex-wife Shannon Price took a lie detector test about the events of the "Diff’rent Strokes" actor’s death — and she admitted she wasn’t surprised to learn she’d failed.

Polygraph examiner George Olivo states that Gary Coleman's ex-wife Shannon Price knows why she did poorly on "Lie Detector: Truth or Deception" when asked about the late star's 2010 fall.

Shannon Price was home when Coleman suffered a bad fall in 2010. She then made the decision to take the former child star off of life support at the hospital.
