Former heavyweight champ Mike Tyson said he doesn't want to know why his 4-year-old daughter died suddenly at her mother's Phoenix home last Spring.

In a candid interview with Oprah Winfrey set to air dtoday, the heartbroken boxing star said he had no interest in learning what led to the death of little Exodus a day after her neck was caught in the cord of a treadmill last May.

"If I know, then there might be a blame for it," Tyson said. "And if there's somebody to blame for it, there will be a problem." 

Exodus was on life support in critical condition at an Arizona hospital after she was found by her 7-year-old brother in the exercise room of her mother's home with her neck wrapped in the electrical cord of a treadmill.

"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," Tyson told the talk show queen, "because I've been that direction. I know where that's gonna lead me. I know I'm not gonna win." 

Tyson, 42, has had a career and personal life riddled with turmoil including a messy public divorce, a rape conviction and being disqualified from the sport for biting Evander Holyfield's ear during a 1997 fight.

Tyson told Oprah his family is his "biggest asset" and after a career or ups and downs his kids are "the only thing that matters to me now."
