Exodus Tyson's 7-year-old brother found her Monday with her neck in a cord dangling from the exercise machine, police Sgt. Andy Hill said.

"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."

"Our sympathies go out to the family," Hill said Tuesday.

"Somehow she was playing on this treadmill, and there's a cord that hangs under the console — it's kind of a loop," Hill said. "Either she slipped or put her head in the loop, but it acted like a noose, and she was obviously unable to get herself off of it."

Exodus's mother took her daughter out of the cable, called 911 and attempted to revive her.

Responding officers and firefighters performed CPR on the little girl. She was rushed to nearby St. Joe's Hospital after she was found around 10:30 a.m. local time, MyFOXPhoenix.com reported.

Hill said former heavyweight champion Tyson, 42, had been in Las Vegas but flew to Phoenix immediately after learning of the accident.

"The Tyson family would like to extend our deepest and most heartfelt thanks for all your prayers and support, and we ask that we be allowed our privacy at this difficult time," the boxer said in a statement.

Brief footage from local TV station KTVK showed Tyson arriving at the hospital in a white button-up and black pants, and looking around with a frown before going inside.

Hill said everything in the investigation pointed to a "tragic accident."

"There's nothing in the investigation that revealed anything suspicious," he said.

We send our deepest sympathies to the Tyson family. No parent should ever have to bury a child.
