One day after she was found hanging on a treadmill cord, Exodus Tyson was pronounced dead.

The 4-year-old daughter of boxer Mike Tyson was discovered by her 7-year-old brother Monday morning. According to police, the little girl either slipped or placed her head in a loop that was hanging under the equipment’s console.

Mike, who had been in Vegas at the time of the accident, immediately flew to Phoenix to be with Exodus. Unfortunately, the child had been listed in critical condition since her arrival at St. Joe’s Hospital. Approximately 24 hours later, Exodus officially passed away.

“There are no words to describe the tragic loss of our beloved Exodus. 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,” the girl’s family said in a statement.
