(CBS/WKMG/AP) ORLANDO, Fla. - In the second part of Casey Anthony's parents' interview with Dr. Phil McGraw, the two discussed their differing opinions of how their 2-year-old granddaughter Caylee died in 2008.
George Anthony told McGraw on the "Dr. Phil Show," that he does not believe that Caylee died by accidental drowning, reports CBS affiliate WKMG.
"If Caylee drowned, why the elaborate coverup?" George Anthony asked, reports the station.
Instead, George Anthony said he more than likely believes that his daughter, possibly along with friends, had given Caylee too much of a chemical, possibly Zanex or chloroform, to sedate Caylee because their daughter Casey wanted more freedom.
Cindy Anthony disagreed with her husband, saying she had never heard her husband discuss that theory until right then. She does not believe the drug theories because there was no evidence that Casey ever did drugs, nor did toxicology results show that Caylee had been drugged. Cindy Anthony believes Caylee's death was an accident based on the not guilty verdict in the trial.
Both of the Anthonys expressed anger over the way Caylee's remains were disposed of. Her body was found in plastic bags in a swampy wooded area near their Orange County home.
"How could they do that to her?" Why didn't she (Casey) tell us?" George Anthony said.
Cindy Anthony said she would never dispose of the body of someone she loved like that. But she defended her daughter saying that Casey Anthony believes that someone's soul leaves their body as soon as they die, so the body was no longer Caylee.
Caylee Anthony was the focus of a wide-ranging search after her disappearance in June 2008. Casey Anthony told police that a fictitious babysitter had kidnapped the child. The 25-year-old maintained the same story to her family until the child's skeletal remains were found in a wooded area in December 2008 not far from the Anthony family home.
Casey Anthony was found not guilty of murder in Caylee's death on July 5. She is currently serving one year of probation for an unrelated check fraud conviction.
Cindy Anthony told McGraw that she prayed nightly during the past three years that if Casey was somehow responsible for Caylee's death that she'd go to jail.
"When that verdict came in and Casey was found not guilty, I got my answer," Cindy Anthony said. "...I'm not gonna be her judge and jury. God is her judge and he set her free."
