28-year-old William LaFever has been found after spending three weeks lost in the Utah desert. "Good Morning America" reports autistic LaFever survived by eating frogs and drinking river water. KUTV reports the man was found sitting in the Escalade River, too weak to stand and with only the clothes on his back. LaFever had a dog with him at the start of his hike, but it was not there when a UHB helicopter spotted him. LaFever is now in the hospital with no word on his condition.
