Reddington Township, ME (NEWS CENTER) -- Geraldine Largay was a thru-hiker on the Appalachian Trail. On July 22, 2013, she stepped off the trail to go to the bathroom. She was never seen alive again.

She reported in her diary that she walked three to four miles looking for the trail. She would set up her final camp about a mile away after having climbed three ridges and crossed two streams.

She repeatedly tried to text her husband who awaited at the next trail head.

Her story and the ensuing search are intriguing and prompt many questions. Dee Dauphinee, a veteran search and rescue worker and an author, is writing a book about Ms. Largay's final days. The book will be called "When You Find My Body," which are words written in her diary.
