(CNN)For two years, the whereabouts of Geraldine "Gerry" Largay had confounded authorities in Maine. Largay, a 66-year-old experienced hiker from Brentwood, Tennessee, disappeared while trekking the Appalachian Trail in July 2013. Hundreds of people searched for her. There wasn't a single clue. On Wednesday, a single person, a surveyor, came across bones, clothing and gear just over a half mile from the trail.
