In an emotional interview on The Oprah Winfrey Show Monday, former heavyweight boxing champion Mike Tyson tells Oprah that he was enraged over the death of his 4-year-old daughter Exodus last May. The little girl choked in a fatal treadmill accident in her mother’s Arizona mansion, but Tyson says he doesn’t want to know what went wrong.

“You don’t want to know?” Oprah asked

“If I know, then there might be a blame for it,” Iron Mike replied. “And if there’s somebody to blame for it, there will be a problem.”

He added: “My first instinct was a lot of rage, you know, and I was so happy that I had the tools in life, you know, to not go in that direction because I’ve been that direction. I know where that’s gonna lead me. I know I’m not gonna win.”
