Former heavyweight champion Mike Tyson says he doesn't want to know what led to his 4-year-old daughter's death. During an interview on “The Oprah Winfrey Show” that aired Monday, Tyson called his daughter Exodus “my angel.” Tyson told Winfrey that he didn't want to know details of her death because “if somebody's to blame for it there will be a problem.” The former boxer says his first instinct was rage but now he has no animosity or anger toward anyone.
