The two-hour special,Casey Anthony’s Parents: The Lie Detector Test, airing on Jan. 4 at 9 p.m. ET/PT on both A&E and Lifetime, delves into the 2008 case that made international headlines. Caylee’s death caused a bitter divide between the grandparents and the girl’s mother, Casey Anthony, who was charged and later acquitted of her killing in 2011. (A trailer for the special is shown below.)

Over the years, each has given different versions of what happened on June 16, 2008, when Caylee was last seen.

George and Cindy agreed to take the polygraph examination after Casey alleged last year in a three-part series,Casey Anthony: Where The Truth Lies, on Peacock, that her father molested her and her daughter and that he was responsible for the child’s death.
