Casey Anthony's parents are opening up about their daughter's life and the events surrounding the death of their granddaughter Caylee.
"I think Casey is mentally ill. I really do," Cindy said. "She's never had her seizures worked up."
Cindy then speculated that it was a "a possibility" Caylee's death happened while Casey was having a seizure.
"She doesn't remember when she's had a seizure, unless she's bitten her tongue or something," she said.
This lines up with a previous claim from one of Casey's trial attorneys, Cheney Mason, who said Casey "blacked out" during the time of Caylee's death.
"I believe that Casey's mind, in some dimension, I guess the common word would say 'snapped,'" Mason said. "She didn't go crazy by any means — but blackout — completely a blackout — of what went on and what happened."
Casey was tried for the 2008 death of Caylee but was found not guilty on murder, manslaughter and child abuse charges.
