Comedian Sarah Silverman is making no joke about how her brother died when he was a baby … claiming in a new interview he was killed by their grandfather in a rage.
The “Don’t Look Up” actress shared the head-turning story in her new interview with Rolling Stone, revealing she learned the truth behind how her brother died at just 3 months old … after being lied to her entire life.
She tells RS her father, Donald Silverman, finally came clean after watching a Manhattan production of her memoir-turned-musical five nights in a row in 2022. Notably … there’s a joke in the musical about her brother Jeffrey’s death.
After the fifth night, she claims Donald made his way backstage and told her … “‘I always felt that he was crying or something, and my dad shook him. He shook him in a rage and killed him.'”
Sarah recalls the room going quiet and her manager gasping in disbelief — but it wasn’t too much of a shocker for her.
She explains … “As soon as he said it, it was like, ‘Of course, that’s what happened.’ His mother always stood by her husband. She watched him beat the s*** out of her son.”

She also says something always seemed off about the story of Jeffrey’s death, noting … “The story was that something happened with the crib, and Jeffrey’s little body slid and he got suffocated. But if you look back, there was never a lawsuit with the crib company or anything.”
Sarah says her dad dropping such a huge piece of information so casually was the norm — adding that he once claimed a school priest fondled him while they were playing a game of poker.
Donald died a year after sharing the truth about Sarah’s brother — who died before she was born.
Sarah said in a May 2023 Instagram post Donald passed with family by his side, who “surrounded him with love and singing and very dark f***ed up jokes this final week.”
