PHOENIX -- The 4-year-old daughter of boxer Mike Tyson died at a hospital Tuesday, a day her neck apparently got caught in a treadmill cord at her Phoenix home.

Exodus Tyson was pronounced dead just before noon, police spokesman Andy Hill said. She had been on life support since the accident Monday.

Police said Exodus either slipped or put her head in the loop of a cord hanging under the console. Her 7-year-old brother found her and told their mother. She took Exodus off the cord, called 911 and tried to revive her.

Responding officers and firefighters performed CPR as they took the girl to the hospital.

Former heavyweight champion Tyson was in Las Vegas at the time of the accident and flew Monday to Phoenix, where he was seen entering the hospital.

Tyson spokeswoman Cynthia Schwartz said the family had not arranged a funeral yet and would release a statement later.
