Mike Tyson

Mike Tyson's 4-year-old daughter, Exodus Tyson, has died after accidentally hanging herself on a piece of exercise equipment at home.

Phoenix Police Department Officer James Holmes told TVGuide.com that Exodus Tyson died at 11:45 a.m. (MST) in what he called a "tragic accident." An autopsy is expected to be performed. Holmes said the family is asking for privacy in the matter.

Tyson's daughter was put on life support after she was discovered Monday with her neck caught in a treadmill cord that hangs from the machine's console. Her mother had removed the cord and tried to revive her before she was rushed to a Phoenix hospital.

The former heavyweight boxing champ was in Las Vegas, but flew to Phoenix immediately after the accident.
