Garfield County sheriff's officials say Oaklee Sidwell was playing with friends on the trampoline in her backyard Tuesday in small town of Panguitch. She was the last one sitting on the large trampoline, putting on her shoes, when the sudden gust lifted it and sent it airborne.
The girl fell off the trampoline at some point before it came to rest half a football field away.
She was taken to a local hospital and later flown to a Salt Lake City hospital, where she died Wednesday from multiple injuries.
Sheriff's spokeswoman Cheryl Church says the trampoline was properly assembled, was anchored to the ground and had a safety net. She says it was a tragic, freak accident that has affected the entire county.
