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

National Park After Dark
Hosted by two friends who share a passion for the wilderness and a fascination with what can go wrong there, each week hosts Danielle and Cassie explore the darker side of our National Parks and explore these treasured places in a whole new way - because behind the iconic arches and towering trees lie layered histories, grisly encounters, extraordinary stories of survival, tragic ends and so much more. But it isn’t always chills and thrills. By sharing inspiring tales and their desire for protecting our planet’s wild places, they hope the show will inspire listeners to lace up their own hiking boots and take a walk into the wild to create meaningful adventures of their own.
