SEATTLE (AP) — A woman who spent more than a week trapped in the wreckage of her vehicle has been upgraded to serious condition, a hospital spokeswoman said Sunday.

Tanya Rider, 33, was admitted in critical condition Thursday with kidney failure and other injuries after her mangled SUV was found in a ravine off a highway suburban Seattle.

She remained in the intensive care unit Sunday, said Susan Gregg-Hanson, spokeswoman for Harborview Medical Center.

Rider's kidneys failed because of toxins from a muscle injury and dehydration. Doctors say her brain function is normal. She also broke her collar bone and dislocated her shoulder and has pressure sores from being held by the seat belt, probably upside down.
