Exodus Tyson was pronounced dead just before noon, police Sgt. Andy Hill said. She had been on life support and police have said their investigation showed her injury on Monday was a "tragic accident."
"There are no words to describe the tragic loss of our beloved Exodus," the family said in a statement. "We ask you now to please respect our need at this very difficult time for privacy to grieve and try to help each other heal."
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.
The family's home is in a modest, quiet neighborhood. Neighbors say they saw Tyson there from time to time and the children played outside regularly.
Dinka Radic, who lives across the street, says the little girl would ask her if she had any chocolate in the house. When Radic would get some and give it to her, Exodus would hug the woman's knees and "kiss, kiss, kiss."
The neighborhood contrasts starkly with the lavish lifestyle Tyson had through his tumultuous years of boxing, when he spent tens of millions of dollars and says he had millions more stolen from him by unscrupulous associates. During two years at the height of his career, he earned $140 million.
The death of his child in such an unusual accident adds an awful chapter to the boxer's troubled life.
