Casey Anthony’s father maintained a stony silence Wednesday after his daughter claimed in a new documentary that he is to blame for her daughter’s death — and that he had sexually abused her.

George Anthony bore a grave look as he walked across an Orlando, Florida, parking lot. He also looked away and refused to answer repeated questions about the bombshell allegations as he closed the trunk of his car.

His wife, Cindy, threatened to call the cops, but also wouldn’t speak on the shocking claims.

Casey Anthony, who shot to notoriety over the 2008 death of her 2-year-old daughter, Caylee, made the bombshell allegation in Peacock’s new docuseries about her. It is the first time she has spoken on camera in 11 years.

“It all comes back to my dad,” she said of the 71-year-old ex-cop.

Her father was the key witness in the prosecution’s attempt to convict her of first-degree murder in Caylee’s death — but the jury found her not guilty. 

Anthony said her father repeatedly raped her, and she fears he abused Caylee and then killed her to cover it up.

“He’d put a pillow over my face and smother me to knock me out … I’m sure there were times where I was incapacitated as a child where my body was limp and lifeless,” she said.

“I know what he did to me — and that was my fear. I had one job — to keep her safe,” she said of her daughter. “I failed her again and again and again, because I still protected the person who hurt me,” Anthony said of her dad.

“I did protect my abuser — and protected her abuser. And that crushes me.”

George Anthony did not respond to questions from the documentary producers, the show said, but he has repeatedly denied abusing Casey. He also denies having any role in the death of his granddaughter.

“Casey Anthony: Where The Truth Lies” streams on Peacock from Nov. 29.
