Vital Statistics at Time of Disappearance
Details of Disappearance
Trenny was last seen on October 8, 1976. Gibson seemingly vanished into thin air while on a hiking trip with her Bearden High School class. The students were hiking from the parking area just below Clingmans Dome to Andrews Bald when Gibson was last seen hiking toward the parking lot. Although Trenny was walking alone, there were groups reportedly behind and in front of her but no one claimed to have seen anything. During the search for Trenny, scent dogs followed her trail to the highway before it was lost. The search for Gibson lasted several months before it was officially called off.
