Teen Vanishes During School Field Trip
Trenny Gibson was last seen in the Great Smoky Mountains 45 years ago.
Trenny Lynn Gibson was a 16-year-old who lived with her parents and three siblings in Knoxville, Tennesse. Her brother Robert Otis Gibson Jr., who was a couple of years older, had recently returned home from Navy boot camp in Florida. The two were very close and Trenny was excited to spend time with him.
