June 16, 2008: the last day 2-year-old Caylee Anthony is seen alive.
One month later, her grandmother Cindy Anthony franticly calls 911 to report her granddaughter is missing. Casey Anthony claims that a babysitter kidnapped her daughter. By October, when nothing Casey tells police turns out to be true, she is arrested and charged with Caylee's death, even though Caylee is still missing.
On December 11, Caylee's remains are found in a garbage bag, dumped in a wooded area near the Anthony home. Eight days later, Caylee's death is ruled a homicide. Prosecutors announce they will seek the death penalty against her.
At Casey Anthony's trial, her lawyer first made claims that George Anthony was molesting his daughter and that he staged Caylee's death to look like a drowning to cover up that he may have been abusing his granddaughter as well.
Those claims, made again after Casey Anthony is acquitted of the death, have haunted the Anthonys for years.
Now, George and Cindy Anthony agree to take a lie detector test in front of cameras for the A&E network special "Casey Anthony's Parents: The Lie Detector Test."
What happened when he is asked if he had anything to do with Caylee's death?
