Tatum O’Neal has blamed (https://www.datalounge.com/thread/36490325-tatum-o-neal-blames-dead-father-for-half-brother-s-troubled-life) half-brother Redmond’s shocking descent into a devil-horned suspected stabber on years of “horrifying and cruel” abuse by their late dad, Hollywood legend Ryan O’Neill.

The former child star gave her damning indictment after Redmond made a terrifying vision with horns tattooed on his head as he appeared in a California court charged with attempted murder.

“He’s doing very poorly, honey, very poorly,” Tatum, 62, told the Daily Mail of her troubled half-brother, the only child of Ryan O’Neal and Farrah Fawcett. “I love Red dearly, but he’s gotten heavy. He never even began a real life,” she said.
