Mike Tyson's four-year-old daughter died May 26 of injuries sustained in a freak home accident. The champion boxer immediately flew to Arizona.

Exodus Tyson was found Monday morning hanged from a cord that was connected to a treadmill in the family’s activity room in their Phoenix, Arizona home. She was discovered when her mother, who was cleaning in another room, sent the girl’s seven-year-old brother in to check on her.

Police say Exodus was playing on the exercise machine at the time of the mishap. Her 7-year-old brother discovered her and called for his mother, who was cleaning in a separate room at the moment of the accident. She called 911, and the child was taken to St. Joseph's Hospital. (Police have not released the mother's name.)

Tyson, 42, was in Las Vegas at the time, but has since arrived in Phoenix to be by his daughter's side.

“Mike was very dedicated to that baby,'' said Sig Rogish, a longtime friend of Tyson and his former agent. “I think every parent's greatest fear is that they live beyond their children. I know Mike has had his troubles in his life, but he's always been a good father.”
