Watch Casey Anthony's Parents Explain Her Seizures To Dr. Phil

As we previously reported, George and Cindy Anthony have come up with a new theory to explain their granddaughter’s death — Casey Anthony suffered seizures.

In this clip from the interview, Dr. Phil interrogates them on this new information that “America has never heard before.”

He really doesn’t let them through any cracks! He knows what he’s talking about!

We can’t really believe they didn’t bring this up before, either. More lies???
