261: The Disappearance of Trenny Gibson. Great Smoky Mountains National Park.

National Park After Dark

What began as an afternoon high school field trip to observe plants became one of the Great Smoky Mountains National Park’s most enduring and puzzling missing persons cases when 16-year-old Trenny Gibson vanished from a trail amongst 40 other students. Her story has stumped investigators and broken hearts for decades, but there is still hope that someone, somewhere knows something that can bring answers and peace.
